With climate change, the oceans are becoming more acid and that is a threat to the dungeness crab, according to a study by the US National Oceanic and Atmospheric Administration.
The study says ocean acidification expected to accompany climate change may slow development and reduce survival of the larval stages of Dungeness crab.
The dungeness crab is a key component of the Northwest marine ecosystem and vital to fishery revenue from Oregon to Alaska.
The research by NOAA Fisheries’ Northwest Fisheries Science Center in Seattle indicates that the declining pH anticipated in Puget Sound could jeopardize populations of Dungeness crab and put the fishery at risk. The study was recently published in the journal Marine Biology.
Ocean acidification occurs as the ocean absorbs carbon dioxide from the combustion of fossil fuels. Average ocean surface pH is expected to drop to about 7.8 off the West Coast by 2050, and could drop further during coastal upwelling periods.

Dungeness crab is the highest revenue fishery in Washington and Oregon, and the second most valuable in California, although the fishery was recently closed in some areas because of a harmful algal bloom. The Dungeness crab harvest in 2014 was worth more than $80 million in Washington, $48 million in Oregon and nearly $67 million in California
“I have great faith in the resiliency of nature, but I am concerned,” said Jason Miller, lead author of the research, which was part of his dissertation. “Crab larvae in our research were three times more likely to die when exposed to a pH that can already be found in Puget Sound, our own back yard, today.”
Scientists collected eggs from Dungeness crabs in Puget Sound and placed them in tanks at the NWFSC’s Montlake Research Laboratory. The tanks held seawater with a range of pH levels reflecting current conditions as well as the lower pH occasionally encountered in Puget Sound when deep water wells up near the surface. Larvae also went into tanks with the even lower-pH conditions expected with ocean acidification.
“The question was whether the lower pH we can expect to see in Puget Sound interferes with development of the next generation of Dungeness crab,” said Paul McElhany, a NOAA Fisheries research scientist and senior author of the paper. “Clearly the answer is yes. Now the question is, how does that play out in terms of affecting their life cycle and populations overall?”
Larvae hatched at the same rate regardless of pH, but those at lower pH took longer to hatch and progressed through their larval stages more slowly. Scientists suggested that the lower pH may reduce the metabolic rate of embryos. That could extend their vulnerable larval period, or could jeopardize the timing of their development in relation to key food sources, researchers suggested.
Larval survival also dropped by more than half at lower pH. At pH 8.0, roughly equivalent to seawater today, 58 percent of the crab larvae – called zoeae – survived for 45 days. At pH 7.5, which sometimes occurs in Puget Sound now, survival was 14 percent. At pH 7.1, which is expected to roughly approximate the pH of water upwelling on the West Coast with ocean acidification, zoeae survival remained low at 21 percent.
“Areas of greatest vulnerability will likely be where deep waters, naturally low in pH, meet acidified surface waters,” such as areas of coastal upwelling along the West Coast and in estuary environments such Hood Canal, the new study predicts.
The United States says acidification of the oceans means there is an already growing risk to the northwest coast fishery, including crab and salmon, according to studies released by the National Oceanic and Atmospheric Administration.
As more carbon dioxide is released into the atmosphere and absorbed by the oceans, the water is becoming more acidic and that affects many species, especially shellfish, dissolving the shells.
A NOAA study released today of environmental and economic risks to the Alaska fishery says:
Many of Alaska’s nutritionally and economically valuable marine fisheries are located in waters that are already experiencing ocean acidification, and will see more in the near future…. Communities in southeast and southwest Alaska face the highest risk from ocean acidification because they rely heavily on fisheries that are expected to be most affected by ocean acidification…
An earlier NOAA study, released in April, identified a long term threat to the salmon fishery as small ocean snails called pteropods which are a prime food source for pink salmon are already being affected by the acidification of the ocean.

NOAA says:
The term “ocean acidification” describes the process of ocean water becoming more acidic as a result of absorbing nearly a third of the carbon dioxide released into the atmosphere from human sources. This change in ocean chemistry is affecting marine life, particularly the ability of shellfish, corals and small creatures in the early stages of the food chain to build skeletons or shells.
Today’s NOAA study is the first published research by the Synthesis of Arctic Research (SOAR) program, which is supported by an US inter-agency agreement between NOAA’s Office of Oceanic and Atmospheric Research and the Bureau of Ocean Energy Management (BOEM) Alaska Region.
Des Nobles, President of Local #37 Fish [UFAWU-UNIFOR] told Northwest Coast Energy News that the fisheries union and other fisheries groups in Prince Rupert have asked both the Canadian federal and the BC provincial governments for action on ocean acidification. Nobles says so far those requests have been ignored,
Threat to crabs
The studies show that red king crab and tanner crab grow more slowly and don’t survive as well in more acidic waters. Alaska’s coastal waters are particularly vulnerable to ocean acidification because of cold water that can absorb more carbon dioxide and unique ocean circulation patterns which bring naturally acidic deep ocean waters to the surface.
“We went beyond the traditional approach of looking at dollars lost or species impacted; we know these fisheries are lifelines for native communities and what we’ve learned will help them adapt to a changing ocean environment,” said Jeremy Mathis, Ph.D., co-lead author of the study, an oceanographer at NOAA’s Pacific Marine Environmental Laboratory in Seattle, and the director of the University of Alaska Fairbanks School of Fisheries and Ocean Sciences Ocean Acidification Research Center.
As for Dungeness crab, Sarah Cooley, a co-author of the Alaska study, who was with the Woods Hole Oceanographic Institution at the time, told Northwest Coast Energy News, “The studies have not been done for Dungeness crab that have been done for king and tanner crab, that’s something we’re keenly aware of. There’s a big knowledge gap at this point.” She says NOAA may soon be looking at pilot study on Dungeness crab.

Risk to Salmon, Mackerel and Herring
In a 2011-2013 survey, a NOAA-led research team found the first evidence: “that acidity of continental shelf waters off the West Coast is dissolving the shells of tiny free-swimming marine snails, called pteropods, which provide food for pink salmon, mackerel and herring.”
The survey estimated that the percentage of pteropods along the west coast with dissolving shells due to ocean acidification had “doubled in the near shore habitat since the pre-industrial era and is on track to triple by 2050 when coastal waters become 70 percent more corrosive than in the pre-industrial era due to human-caused ocean acidification.”
That study documented the movement of corrosive waters onto the continental shelf from April to September during the upwelling season, when winds bring water rich in carbon dioxide up from depths of about 120 to 180 metres to the surface and onto the continental shelf.
“We haven’t done the extensive amount of studies yet on the young salmon fry,” Cooley said. “I would love to see those studies done. I think there is a real need for that information. Salmon are just so so important for the entire Pacific Northwest and up to Alaska.”
In Prince Rupert, Barb Faggetter, an independent oceanographer whose company Ocean Ecology has consulted for the fisherman’s union and NGOs, who was not part of the study, spoke generally about the threat of acidification to the region.
She is currently studying the impact of the proposed Liquified Natural Gas terminals that could be built at Prince Rupert near the Skeena River estuary. Faggetter said that acidification could affect the species eaten by juvenile salmon. “As young juveniles they eat a lot of zooplankton including crustaceans and shell fish larvae.”
She added, “Any of the shell fish in the fishery, including probably things like sea urchins are all organisms that are susceptible to ocean acidification because of the loss of their capacity to actually incorporate calcium carbonate into their shells.”
Faggetter said her studies have concentrated on potential habitat loss near Prince Rupert as a result of dredging and other activities for liquified natural gas development, She adds that ocean acidification “has been a consideration that climate change will further worsen any potential damage that we’re currently looking at.”
Her studies of the Skeena estuary are concentrating on “rating” areas based on the food supply available to juvenile salmon, as well as predation and what habitat is available and the quality of that habitat to identify areas that “are most important for the juvenile salmon coming out of the Skeena River estuary and which are less important.”
She said that climate change and ocean acidification could impact the Skeena estuary and “probably reduce some of the environments that are currently good because they have a good food supply. If ocean acidification reduces that food supply that will no longer be good habitat for them” [juvenile salmon].
Bongo nets are deployed up to 200 meters deep to catch marine snails (pteropods), which are indicators of the progress of ocean acidification. The pteropod samples were collected during the U.S. West Coast survey cruises in 2011 and 2013. Unlike the US, Canada’s DFO is using models to track what’s happening to pteropods. (NOAA)
The August 2011 NOAA survey of the pteropods was done at sea using “bongo nets” to retrieve the small snails at depths up to 200 metres. The research drew upon a West Coast survey by the NOAA Ocean Acidification Program in that was conducted on board the R/V Wecoma, owned by the National Science Foundation and operated by Oregon State University.
Nina Bednarsek, Ph.D., of NOAA’s Pacific Marine Environmental Laboratory in Seattle, the lead author of the April pteropod paper said, “Our findings are the first evidence that a large fraction of the West Coast pteropod population is being affected by ocean acidification.
“Dissolving coastal pteropod shells point to the need to study how acidification may be affecting the larger marine ecosystem. These near shore waters provide essential habitat to a great diversity of marine species, including many economically important fish that support coastal economies and provide us with food.”
Ecology and economy
Today’s study on the effects of acidification on the Alaska fishery study examined the potential effects on a state where the fishing industry supports over 100,000 jobs and generates more than $5 billion in annual revenue. Fishery-related tourism also brings in $300 million annually to the state.
A map of Alaska shows the economic and ecological risks to parts of the state from ocean acidification. (NOAA)
The study also shows that approximately 120,000 people or roughly 17 percent of Alaskans rely on subsistence fisheries for most, if not all of their dietary protein. The Alaska subsistence fishery is open to all residents of the state who need it, although a majority of those who participate in the subsistence fishery are Alaska’s First Nations. In that way it is somewhat parallel to Canada’s Food, Ceremonial and Social program for First Nations.
“Ocean acidification is not just an ecological problem—it’s an economic problem,” said Steve Colt, Ph.D., co-author of the study and an economist at the University of Alaska Anchorage. “The people of coastal Alaska, who have always looked to the sea for sustenance and prosperity, will be most affected. But all Alaskans need to understand how and where ocean acidification threatens our marine resources so that we can work together to address the challenges and maintain healthy and productive coastal communities.”
The Alaska study recommends that residents and stakeholders in vulnerable regions prepare for environmental challenge and develop response strategies that incorporate community values and needs.
“This research allows planners to think creatively about ways to help coastal communities withstand environmental change,” said Cooley, who is now science outreach manager at Ocean Conservancy, in Washington, D.C. “Adaptations can be tailored to address specific social and environmental weak points that exist in a community.
“This is really the first time that we’ve been able to go under the hood and really look at the factors that make a particular community in a borough or census are less or more vulnerable from changing conditions resulting from acidification. It gives us a lot of power so that we don’t just look at environmental issues but also look at the social story behind that risk.”
As for the southern part of the Alaska panhandle nearest British Columbia, Cooley said, “What we found is that there is a high relative risk compared to some of the other areas of Alaska and that is because the communities there undertake a lot of subsistence fishing, There tend not be a whole lot of commercial harvests in the fisheries there but they are very very important from a subsistence stand point… And they’re tied to species that we expect to be on the front line of acidification, many of the clam species that are harvested in that area and some of the crab species.”
Long term effects
Libby Jewett, Director of the NOAA Ocean Acidification Program and author of the pteropod study said, “Acidification of our oceans may impact marine ecosystems in a way that threatens the sustainability of the marine resources we depend on.
“Research on the progression and impacts of ocean acidification is vital to understanding the consequences of our burning of fossil fuels.”
“Acidification is happening now,” Cooley said. “We have not yet observed major declines in Alaskan harvested species. In Washington and Oregon they have seen widespread oyster mortality from acidification.
“We don’t have the documentation for what’s happening in Alaska right now but there are a lot of studies staring up right now that will just keep an eye out for that sort of thing, Acidification is going to be continuing progressively over the next decades into the future indefinitely until we really curb carbon dioxide emissions. There’s enough momentum in the system that is going to keep acidification advancing for quite some time.
“What we need to be doing as we cut the carbon dioxide, we need to find ways to strength communities that depend on resources and this study allows us to think differently about that and too really look at how we can strengthen those communities.
Faggetter said. “It’s one more blow to an already complex situation here, My study has been working particularly on eel grass on Flora Bank (pdf) which is a very critical habitat, which is going to be impacted by these potential industrial developments and that impact will affect our juvenile salmon and our salmon fishery very dramatically, that could be further worsened by ocean acidification.”
She said that acidification could also be a long term threat to plans in Prince Rupert to establish a geoduck fishery (pronounced gooey-duck).
The popular large 15 to 20 centimetre clam is harvested in Washington State and southern BC, but so far hasn’t been subject to commercial fishing in the north.
NOAA said today’s study shows that by examining all the factors that contribute to risk, more opportunities can be found to prevent harm to human communities at a local level. Decision-makers can address socioeconomic factors that lower the ability of people and communities to adapt to environmental change, such as low incomes, poor nutrition, lack of educational attainment and lack of diverse employment opportunities.
NOAA’s Ocean Acidification Program and the state of Alaska are also developing tools to help industry adapt to increasing acidity.
The new NOAA study is the first published research by the Synthesis of Arctic Research (SOAR) program. which is supported by an inter-agency agreement between NOAA’s Office of Oceanic and Atmospheric Research and the Bureau of Ocean Energy Management (BOEM) Alaska Region.
It comes down to the idea that Harper will approve Gateway “in the national interest,” count on a vote split between the NDP and Liberals in British Columbia to avoid any consequences to the Conservative majority and then leave it up to Enbridge to actually get the job of building the pipeline and terminal project done.
Mason quotes “ a senior member of Mr. Harper’s government,” and while Mason doesn’t say what part of Canada the source is from, (unlikely in my view the source is from BC) what the member told Mason reveals that the Harper government is still mired in it the Matrix-world that has always governed its policy on Northern Gateway.
The first step, apparently coming in the next few days, is that the Harper government “rigorous” new tanker protocols for traffic along the west coast.
Even if the protocols are new, just who is going to enforce those policies?
Mason says:
Even if Gateway and the Kinder Morgan expansion went ahead, he argued, B.C. would still only see about 60 per cent of the annual oil tanker traffic the neighbouring state of Washington deals with. And yet Washington has an exceptionally clean record when it comes to the safe transport of oil in and out of its harbours – this, he noted, while operating under marine safety regulations that are not as rigorous as the ones Ottawa intends to put in place for the shipment of oil along the West Coast.
There are a lot big problems with that statement.
First, there’s an organization that the Mason’s source may have heard of known as the United States Coast Guard. The United States rigorously enforces its “weak” regulations, while Canada’s Coast Guard is plagued by staff shortages and budget cuts.
Second, the State of Washington also rigorously enforces its environmental regulations, not only on the coast but across the state. I have been told by retired British Columbia forestry and environmental officials (not to mention Fisheries and Oceans) that there are often more state environmental watch dogs in most Washington State counties than in all of northern British Columbia where the Northern Gateway is supposed to be going.
The September 2013, report by the US National Oceanographic and Atmospheric Administration on the export of Canadian bitumen sands through the US shows that the Washington Department of Ecology is working on strengthening regulations for both pipelines and (where it’s in state jurisdiction) tanker traffic. The same report says the state of Alaska Department of Environmental Conservation is updating its plans and possible regulations in anticipation that bitumen filled tanker traffic from Kitimat would come close to the coast en route to Asia.
Third, the coast of northern British Columbia is more rugged and stormy than the waters off Washington.
Who pays?
The one factor that the urban media seems to ignore, is the big question.
Who pays?
Who pays to enforce the 209 conditions that the Joint Review Panel imposed on the Northern Gateway project?
If the Harper government announces new tanker regulations in the coming days, who pays to enforce those regulations?
There were no provisions in the February budget for enforcing the 209 conditions. Rather there were continuing budget cuts to the very departments that the JRP ruled must be involved in the studying, planning, implementation and enforcement of the 209 conditions, Environment Canada, Fisheries and Oceans and Transport Canada.
So while Mason says “The federal government will play its part in meeting the five conditions laid out by the B.C. government for support of the project,” the response must be “Show me the money!”
During the recent plebiscite campaign, Northern Gateway finally revealed its plans for the “super tugs” that will escort tankers along the coast and up Douglas Channel. Owen McHugh, a Northern Gateway emergency manager said, “Adding these four or five tugs to the north coast provides a rescue capability that doesn’t exist in this format. So for any large commercial vessel that is traveling on our coast, this capacity to protect the waters of the north coast.” Those tugs and Northern Gateway’s plans to station teams at small bases along the coast means that the company is, in effect, creating a parallel, private, coast guard on the BC Coast.
What about the Coast Guard itself? The Harper government has been gutting Coast Guard resources along the coast even before it had its majority. It closed and dismantled the Kitsilano Coast Guard station in Vancouver. There is more dependence on the Royal Canadian Marine Search and Rescue volunteers, who have to raise money locally for modern rescue boats which cost up to $750,000. The money that government was “generously” giving to RCMSAR had to be split up to 70 stations in 42 communities along the coast as well as its administrative and training staff.
And speaking of boats, what about Coast Guard vessels on the coast? As the Globe and Mail has reported, the government’s shipbuilding program is already over budget and behind schedule. The aim is Arctic/Offshore Patrol Ships and new destroyers. With the crippling of HMCS Protecteur that has raised the concerns about the already troubled supply ship program.
Does anyone notice what is missing from that list? What’s missing are better Coast Guard vessels just to police all the expected tanker traffic on the west coast (whether LNG or bitumen) and no mention of dedicated spill response vessels, which under the “polluter pay” policy will likely be left to private contractors (and hope that the ships are available at the time of a spill)
How will we know?
Then there is the question of how will people even know if the 209 conditions are being enforced; whether or not the reports demanded by the Joint Review Panel are going be sitting on the National Energy Board server and ignored.
There is every indication, given the government’s obsession with secrecy that until there is a disaster the Canadian public will never know what’s going on. Harper’s muzzling doesn’t just cover government scientists, it covers the lowest level of bureaucrats, as District of Kitimat Council found out when low level DFO bureaucrats refused to appear publicly before council to discuss the risk to the Kitimat River.
So the scenario is, according to Mason’s source
“I think once this decision is made, Enbridge could have shovels in the ground the next day,” the member said. “They are ready to go. This means the First Nations could start realizing profits from this right away, as opposed to the promised profits from LNG, which may never materialize. I think they need to think about that.”
First, as part of the blunders is that the Conservatives have always made is the assumption that eventually the First Nations of British Columbia can be paid off, ignoring the commitment of the First Nations, especially on the coast, to protect the environment that sustained them for thousands of years.
While the LNG market is volatile, the “member” forgets that most of the First Nations of British Columbia have opposed the Northern Gateway since Enbridge first floated the idea in 2001. The current LNG rush didn’t start until after Japan shut down its nuclear power plants after the March 2011 earthquake, The first major anti-Enbridge rally, “The Solidarity Gathering of Nations” was held at Kitamaat Village in May 2010.
Writing off BC
It appears that Conservatives, in their election strategy have already written off Gateway opponents:
Still, there is a raw political calculus that needs to be taken into account. Polls measuring support for the pr.oject in B.C. vary, but generally have shown that anywhere from 55 to 60 per cent of the province opposes Gateway and 40 to 45 per cent support it. Isn’t that enough to scare off a government that needs critical votes in B.C. to win another majority?
“Let’s say 60 per cent are against it,” he said. “And that vote splits between the Liberals and the NDP come the next election. Who are the 40 per cent going to vote for?”
Mason also speculates that Harper will approve Gateway to stick it to Barack Obama and the delays on Keystone XL. As he points out that’s a political, not an economic decision.
There are civil disobedience classes being held across northwestern BC this month. Access to Information requests by the Vancouver Observer revealed increased RCMP surveillance of the anti-Gateway movement. There has always been talk of a “war in the woods” if the pipeline project is forced on an unwilling population.
So it comes down to a question that Mason and the Conservatives are avoiding. Mason’s source says Northern Gateway is crucial to the national interest:
“At the end of the day, you have to do what’s right, not what’s politically expedient,” he said. “You have to ask: What’s in the best interests of all Canadians?”
So given all that will the Harper government leave Enbridge to tough it out on its own?
Highly unlikely.
But will the Harper government, with its bean counting obsession on balancing the budget be willing to pay for all that is needed?
Highly likely.
There’s lots of marine clay along the pipeline route, laid down by ancient oceans. That brings to mind just one word. Quagmire, not just the wet, sticky BC mud but a political quagmire.
Iain McKechnie and Dana Lepofsky examine ancient herring fish bones that tell the story about how gigantic herring fisheries were for thousands of years in the Pacific Northwest. (SFU)
The herring, now dwindling on on the Pacific Coast, was once “superabundant” from Washington State through British Columbia to Alaska and that is a warning for the future, a new study says.
A team of scientists lead by Simon Fraser University argue that the archaeological record on the Pacific Coast offers a “deep time perspective” going back ten thousand years that can be a guide for future management of the herring and other fish species.
An archaeological study looked at 171 First Nations’ sites from Washington to Alaska and recovered and analyzed 435,777 fish bones from various species.
Herring bones were the most abundant and dating shows that herring abundance can be traced from about 10,700 years ago to about the mid-nineteenth century with the arrival of Europeans and the adoption of industrial harvesting methods by both settlers and some First Nations.
That means herring were perhaps the greatest food source for First Nations for ten thousand years surpassing the “iconic salmon.” Herring bones were the most frequent at 56 per cent of the sites surveyed and made up for 49 per cent of the bones at sites overall.
The study is one of many initiatives of the SFU-based Herring School, a group of researchers that investigates the cultural and ecological importance of herring.
“By compiling the largest data set of archaeological fish bones in the Pacific Northwest Coast, we demonstrate the value of using such data to establish an ecological baseline for modern fisheries,” says Iain McKechnie. The SFU archaeology postdoctoral fellow is the study’s lead author and a recent University of British Columbia graduate.
Co-author and SFU archaeology professor Dana Lepofsky states: “Our archaeological findings fit well with what First Nations have been telling us. Herring have always played a central role in the social and economic lives of coastal communities. Archaeology, combined with oral traditions, is a powerful tool for understanding coastal ecology prior to industrial development.”
The researchers drew from their ancient data-catch concrete evidence that long-ago herring populations were consistently abundant and widespread for thousands of years. This contrasts dramatically with today’s dwindling and erratic herring numbers.
“This kind of ecological baseline extends into the past well beyond the era of industrial fisheries. It is critical for understanding the ecological and cultural basis of coastal fisheries and designing sustainable management systems today,” says Ken Lertzman, another SFU co-author. The SFU School of Resource and Environmental Management professor directs the Hakai Network for Coastal People, Ecosystems and Management.

Heiltsuk tradition
The paper says that the abundance of herring is additionally mirrored in First Nations’ place
names and origin narratives. They give the example of the 2,400-y-old site at Nulu where herring
made up about 85 per cent of the fish found in local middens. In Heiltsuk oral tradition, it is Nulu where Raven first found herring. Another site, 25 kilometres away at the Koeye River, has only has about 10 per cent herring remains and is not associated with herring in Heiltsuk tradition.
(In an e-mail to Northwest Coast Energy News, McKechnie said “there is a paucity of archaeological data from Kitimat and Douglas Channel. There is considerable data from around Prince Rupert, the Dundas Islands and on the central coast Namu/Bella Bella/ Rivers Inlet area and in southern Haida Gwaii.”)
The study says that the archaeological record indicates that places with abundant herring were consistently harvested over time, and suggests that the areas where herring massed or spawned were more extensive and less variable in the past than today. It says that even if there were natural variations in the herring population, the First Nations harvest did not affect the species overall.
It notes:
Many coastal groups maintained family-owned locations for harvesting herring and herring roe from anchored kelp fronds, eel grass, or boughs of hemlock or cedar trees. Herring was harvested at other times of the year than the spawning period when massing in local waters but most ethnohistorical observations identify late winter and springtime spawning as a key period of harvest for both roe and fish.
The herring and herring roe were either consumed or traded among the First Nations.
Sustainable harvests encouraged by building kelp gardens,wherein some roe covered fronds were not collected, by minimizing noise and movement during spawning events, and by elaborate systems of kin-based rights and responsibilities that regulated herring use and distribution.
Industrial harvesting
Industrial harvesting and widespread consumption changed all that. Large numbers of herring were harvested to for rendering to oil or meal. By 1910, the problem was already becoming clear. In that year British Columbia prohibited the reduction of herring for oil and fertilizer. There were reports at that time that larger bays on the Lower Mainland were “being gradually deserted by the larger schools where they were formerly easily obtained.”
But harvesting continued, in 1927 the fishery on eastern Vancouver Island, Columbia, processed
31,103 tons of herring. The SFU study notes that that is roughly twice the harvest rate for 2012 and would also be about 38 per cent of the current herring biomass in the Strait of Georgia.
In Alaska, reduction of herring began in 1882 and reached a peak of 75,000 tons in 1929.
As the coastal populations dwindled, as with other fisheries, the emphasis moved to deeper water. By the 1960s, the herring populations of British Columbia and Washington had collapsed. Canada banned herring reduction entirely in 1968, Washington followed in the early 1980s.
In the 1970s, the herring population off Japan collapsed, which opened up the demand for North American roe, which targeted female herring as they were ready to spawn. That further reduced the herring population so that the roe fishery is now limited to just a few areas including parts of the Salish Sea and off Sitka and Togiak, Alaska.
The First Nations food, social and ceremonial herring fishery continues.
Government fishery managers, scientists, and local and indigenous peoples lack consensus on the cumulative consequences of ongoing commercial fisheries on herring populations. Many First Nations, Native Americans, Alaska Natives, and other local fishers, based on personal observations and traditional knowledge, hypothesize that local herring stocks, on which they consistently relied for generations, have been dramatically reduced and made more difficult to access following 20th century industrial fishing
Deep time perspective
The SFU study says that some fisheries managers are suggesting that the herring population has just shifted to other locations and other causes may be climate change and the redounding of predator populations.
But the study concludes, that:
Our data support the idea that if past populations of Pacific herring exhibited substantial variability, then this variability was expressed around a high enough mean abundance such that there was adequate herring available for indigenous fishers to sustain their harvests but avoid the extirpation of local populations.
These records thus demonstrate a fishery that was sustainable at local and regional scales over millennia, and a resilient relationship between harvesters, herring, and environmental change that has been absent in the modern era.
Archaeological data have the potential to provide a deep time perspective on the interaction between humans and the resources on which they depend.
Furthermore, the data can contribute significantly toward developing temporally meaningful ecological baselines that avoid the biases of shorter-term records.
Other universities participating in the study were the University of British Columbia, University of Oregon, Portland State University, Lakehead University, University of Toronto, Rutgers University and the University of Alberta.
The list of participants in the oil spill preparedness and response study released last week by the federal government shows two glaring no shows, the District of Kitimat and Rio Tinto Alcan.
The Haisla Nation and the Gitga’at Nation did provide written submissions to the panel.
The expert panel was set up by the federal government to review “oil handling facilities and ship-source oil spill preparedness and response.” The expert panel was to review the “structure, functionality and the overall efficiency and effectiveness of the system, as well as analyzing the requirements for hazardous and noxious substances, including liquefied natural gas.”
The panel also invited any interested groups to submit documents or their own views to be taken into consideration.
Among the stakeholders interviewed by the panel were companies and organizations very familiar to Kitimat; Chevron and Shell, main partners in two of the LNG projects; Enbridge, which has proposed the Northern Gateway Pipeline and Kinder Morgan which has proposed expanding the dilbit pipeline on the Lower Mainland. Other stakeholders included Coastal First Nations, the Prince Rupert Port Authority, SMIT Marine and the Vancouver Port Authority.
As well as the Haisla and the Gitga’at, five west coast municipalities submitted their own reports to the tanker panel, both the city and districts of North Vancouver, the city of Richmond, the District of Ucluelet and the District of West Vancouver. San Juan County in Washington State also made a submission to the panel. So did the Prince Rupert and Vancouver Port authorities.
Chevron, Enbridge, Imperial Oil, Kinder Morgan, Pacific Northwest LNG, Seaspan Marine, and the Union of BC Municipalities, among others also submitted their views to the panel.
So why didn’t the District of Kitimat participate? When it came to the Enbridge Northern Gateway Joint Review, the mayor and council always maintained their neutrality motion meant that the District would not be an active participant. That was always a short sighted viewpoint. The District should have participated actively in the JRP in such a way as to protect the region’s interests where necessary while remaining neutral. If the District of Kitimat sat out the tanker panel because of the Northern Gateway neutrality policy, that was no excuse, because the expert panel’s mandate specifically included LNG.
Tanker traffic is a potential threat to the San Juan Islands (the Gulf Islands on the American side of the border). It is astounding that San Juan County would think that the Canadian tanker panel was important enough to make a submission and the District of Kitimat did not.
What about Rio Tinto Alcan? Kitimat has been a private port for 60 years, run first by Alcan and then by Rio Tinto Alcan. Why wasn’t RTA asked to participate as a stakeholder? Why didn’t RTA make a submission? Those who are pushing the Northern Gateway terminal always like to say that tankers have been calling at Kitimat for those 60 years. That is true. Of course, none of those tankers have been the Very Large Crude Carriers proposed by Northern Gateway. However, those 60 years means that RTA has the expertise on the Port of Kitimat and Douglas Channel. RTA probably has important data that could have helped both the expert panel and Genivar (which pointed out the paucity of data on small and medium sized tankers). In not participating in the tanker panel submissions and possibly not providing valuable data on Douglas Channel, RTA neglected its social responsibility both to the community of Kitimat and the rest of the province of British Columbia.
Supporters of David Black’s Kitimat Clean project to build a refinery about 25 kilometres north of Kitimat have been met by skepticism by experts and economists from the Canadian oil patch who keep telling the people of northwestern British Columbia that to create jobs by adding value to Alberta crude is uneconomic.
The Americans, apparently, have a different view, with plans announced for shipping projects in Washington State that could handle not only oil shale crude from the Bakken Formation in the Dakotas but also Canadian “heavy crude” aimed at refineries in Californa, refineries that would require new or renovated facilities.
So let’s add another question to northwest BC’s skepticism about the Alberta oil patch. Why is uneconomic to refine in Alberta or BC, but apparently increasingly economic to refine in California given the cost of building or rebuilding facilites?
Opponents of the Northern Gateway pipeline have always speculated that any bitumen exported from Kitimat could end up in California rather than markets in Asia.
According to reports, the Vancouver, Washington, project plans to load the bitumen on barges for shipment to California, which is likely to cause a storm of controversy with environmental groups in both states, especially if a barge, which has almost no controls compared to a tanker, foundered and ended up on the coast.
The New York Times, on Oct. 31, looked at the issue in a report Looking for a Way Around Keystone XL, Canadian Oil Hits the Rails. The issue of moving crude by rail has been gaining traction in recent months, with growing opposition to pipeline projects. But where do those long trains of tank cars full of crude go?
Times reporter Clifford Kraus says:
The developing rail links for oil sands range across Canada and over the border from the Gulf Coast to Washington and California. Railways can potentially give Canadian producers a major outlet to oil-hungry China, including from refineries in Washington and California.
According to the Times, the plans call for two Canadian export terminals.
“We want to diversify our markets beyond just moving our product south,” said Peter Symons, a spokesman for Statoil, a Norwegian oil giant that has signed contracts to lease two Canadian oil loading terminals. “We can get that product on a ship and get it to premium markets in Asia.”
The Americans, on the other hand, are looking toward refineries.
Again the Times report says:
Several Washington and Oregon refiners and ports are planning or building rail projects for Canadian heavy crude as well as light oil from North Dakota. The Texas refinery giant Tesoro and the oil services company Savage have announced a joint venture to build a $100 million, 42-acre oil-handling plant in the Port of Vancouver on the Columbia River that could handle 380,000 barrels of oil each day if permits are granted.
Not that everything is clear sailing. The Times says there is resistance to a plan to refine heavy crude in California.
The city of Benicia, Calif., last month delayed the granting of a permit for Valero Energy’s planned rail terminal at its refinery by deciding to require an environmental impact report after residents expressed concerns that Valero would use the terminal to import Canadian oil sands crude.
With access to rail and existing marine infrastructure, the Port of Vancouver is uniquely positioned to serve as a hub for the distribution of North American crude oil to West Coast refining centers. Tesoro and Savage are ideal partners for this project, having already operated in close partnership for almost ten years on the West Coast. The Tesoro-Savage Joint Venture’s combined capabilities, experience and resources are expected to create substantial benefits for the Port and the Vancouver community in the form of sustainable revenue to the Port and local jobs associated with the facility’s construction and operation.
The Tesoro news release quotes Greg Goff, President and CEO of Tesoro.
Building upon the recent success of the rail unloading facility at our Anacortes, Wash., refinery, where we have been delivering Mid-Continent crude oil via unit train in an environmentally sound and cost-effective manner, this project is the ideal next step for Tesoro as we drive additional feedstock cost advantage to the remaining refineries in our West Coast system.
While the Tesoro April release doesn’t specifically mention heavy crude or bitumen from Alberta, in August, Reuters reporting on a Tesoro results conference call said, the project would “supply cheaper U.S. and Canadian crude to refineries all along the West Coast – both its own and those run by competitors.”
The project, which would initially have capacity of 120,000 barrels a day and could be expanded to 280,000 BPD, is the biggest so far proposed to help Pacific Coast refineries tap growing output of inland U.S. and Canadian heavy crudes.
The project, where North Dakota Bakken and Canadian crude would travel by rail to the marine facility in Vancouver, Washington and then barged to refining centers, is being planned with joint venture partner Savage Companies.
The Port of Vancouver facility will have “a lot of flexibility and capability to take different types of crudes, from heavy Canadian crudes to crudes from the Mid-Continent… So we will source crude from where the best place is,” Goff said on Aug. 2. “The facility also was designed to supply the entire West Coast… We can go from as far away as Alaska to Southern California, in those refineries, which we intend to do.”
Reuters also reported
Regulators also are considering Valero’s permit request for a 60,000 bpd rail facility at its 78,000 bpd Wilmington refinery near Los Angeles, but in June the area pollution regulator said it would take 18 months to finish an environmental review, permitting and construction.
Alon Energy USA also is seeking permits for a rail facility at its Southern California refining system, which shut down late last year as losses mounted on high imported crude costs and low asphalt demand. The company hopes to get those permits by year-end.
Valero spokesman Bill Day on Friday declined to say whether Valero would be interested in tapping inland and Canadian crude through the Tesoro project, but noted that the company values flexibility in getting cheaper crudes to its refineries.
Asked today about the New York Times report, (at the time of his regular news conference, he hadn’t read the story) Skeena Bulkley Valley MP Nathan Cullen said, “I mean there’s been so much uncertainty, in large part created by this government with respect to moving oil anywhere. This is another proposal, it seems every week you wake up, open the papers and there’s another proposal. Some of them are legitimate, some of them are snake oil.
“This one I’m not familiar with, so I can’t make specific comments on it, I will certainly look at it because I’m very interested in energy on the west coast. I’d have to see, given the government we have in Ottawa right now, they’re not friends to communities and First Nations and certainly not friends to the oil sector because they keep causing so much concern within the broader public and hurt the companies’ ability to gain social licence to get a project going.”
Tiny amounts of copper in a river affect a salmon’s sense of smell, making it harder to avoid predators, according to a study at Washington State University.
Jenifer McIntyre says the copper means that a salmon can’t detect another compound that ordinarily alerts them to be still and wary.
The minute amounts of copper can come from mines and even the brake linings of cars.
“A copper-exposed fish is not getting the information it needs to make good decisions,” says McIntyre, a postdoctoral research associate in WSU’s Puyallup Research and Extension Center, whose study built on earlier work that showed that copper can affect a salmon’s sense of smell and thus changing its behavour.
McIntyre put the two together, exposing juvenile coho salmon to varying amounts of copper and placing them in tanks with cutthroat trout, a common predator.
Healthy salmon can smell compounds in the water that are released when another fish is damaged. That substance, called Schreckstoff, German meaning “scary stuff,” alerts fish to nearby predators.
In her experiments, conducted in a four-foot-diameter tank, fish that weren’t exposed to copper would freeze in the presence of Schreckstoff, making it harder for motion-sensitive predators to detect them. On average, half a minute would go by before they were attacked.
But salmon in water with just five parts of copper per billion failed to detect the Schreckstoff and kept swimming. They were attacked in about five seconds.
“It’s very simply and obviously because predators can see them more easily,” says McIntyre. “They’re not in lockdown mode.”
The unwary exposed fish were also more likely to be killed in the attack, being captured 30 percent of the time on the first strike. Unexposed fish managed to escape the first strike nearly nine times out of ten, most likely because they were already wary and poised to take evasive action.
McIntyre also noticed that the behavior of predators was the same whether or not they had been exposed to copper.
Copper finds its way into streams and marine waters from a variety of sources, including motor vehicle brake linings, pesticides, building materials and protective boat coatings. Actual amounts will vary from undetectable in rural or forested areas to elevated in urban areas, especially when runoff from a storm washes roads of accumulated brake dust and other contaminants.
With testimony from McIntyre’s NOAA colleagues and others, the Washington State legislature in 2010 started phasing out copper brake pads and linings over the next 15 to 20 years. According to the state Department of Ecology, brake pads are the source of up to half the copper in the state’s urban waterways.
McIntyre used concentrations of between 5 and 20 parts per billion but has sampled highway runoff with 60 times as much copper. Copper’s effect is mediated by organic matter, which can make the metal unavailable to living things.
“My scenarios are potentially more like a hard-rock copper mining situation than storm water runoff, which typically carries dissolved organic matter along with the copper and other contaminants,” McIntyre says.
A number of large copper mining projects are proposed for the northwest region including, the controversial Taseko’s Prosperity copper mine near Williams Lake which was stopped after the local First Nations and environmental groups opposed the use of one lake for a tailings pond. Taseko is now trying to revive the project. There area also a number of copper mine proposals for the both the northwest BC coast and the Sacred Headwaters region, source of the major salmon rivers, the Skeena, Nass and Stikine. There is also a proposed copper mine Pebble Mine, at Bristol Bay, Alaska, another prime area for sockeye salmon.
Environmental impact of the Canadian copper mine projects are likely to be affected by the provisions of Bill C-38 which speed up environmental assessment and essentially gut habitat protection for fisheries.
Her research, conducted for a University of Washington doctorate with colleagues at UW and the National Oceanic and Atmospheric Administration, appears in the latest issue of the journal Ecological Applications.
Kinder Morgan, of Houston, Texas, said Thursday, April 12, 2012, it plans to proceed with expansion of the Trans Mountain pipeline system from Alberta to the BC Lower Mainland. The company made the announcement after what the energy industry calls an “open season,” a search for customers where it received “strong binding commitments” from existing and new shippers. They pledged commercial support to an additional 660,000 barrels per day of bitumen sands crude from the pipeline. Demand has been high and reports say Kinder Morgan has had to ration petroleum products for its existing customers.
The 20 year commitment from the customers means the pipeline capacity would increase to 850,000 barrels per day from 550,000 barrels. That would make the eventual capacity of the Kinder Morgan pipeline much larger than Enbridge Northern Gateway’s proposed 525,000 barrels per day.
In a release, Ian Anderson, president of Kinder Morgan Canada said, “We are extremely pleased with the strong commercial support that we received through the open season, which reinforces the appeal of our project and our approach. This strong commercial support shows the market’s enthusiasm for expanding market access for Canadian crude by expanding an existing system.”
Now Kinder Morgan has to get approval from the National Energy Board and acceptance from the local communities along the pipeline route from the Alberta bitumen sands to the terminals and refineries in Vancouver and in Washington state and for tanker export.
“This support from the market better defines the project and enables Kinder Morgan Canada to fully engage the local communities. We are still early in the engagement process of the project,” Anderson said in the release. “We share respectful, open relationships with many communities and organizations interested in our business. We are committed to an 18 to 24 month inclusive, extensive and thorough engagement on all aspects of the project with local communities along the proposed route and marine corridor, including First Nations and Aboriginal groups, environmental organizations and all other interested parties. We will also consider providing financial support to local communities for environmental initiatives. We have been planning for this day for many years and we are keen to start in depth engagement this summer.”
Kinder Morgan says the preliminary scope of the proposed project includes:
Projected capital cost of approximately $5 billion.
Twinning the existing pipeline within the existing right-of-way, where possible.
Adding new pump stations along the route.
Increasing the number of storage tanks at existing facilities.
Expanding the Westridge Marine Terminal.
Anderson added, “We anticipate filing a facilities application initiating a regulatory review with the National Energy Board in 2014. If our application is approved, construction is currently forecast to commence in 2016 with the proposed project operating by 2017.”
In addition to extensive engagement, the company will conduct traditional land use and environmental and socio-economic studies, and undertake detailed engineering and design studies, the release says.
The Trans Mountain proposal, like the Enbridge Northern Gateway pipeline is a “facilities application,” and one uncertainty facing the company will be the highly controversial decision by Stephen Harper’s Conservative government to speed up all future project applications of that type. Environmental groups have already expressed strong opposition to the speed up, while the energy industry has said faster application approval is long over due.
As well as the facilities application, Kinder Morgan says it will file “a commercial tolling application to review the company’s proposed commercial structure for the expansion. This filing, which is anticipated in summer 2012, will seek National Energy Board approval on how the company will charge its customers for transporting their product through the proposed expanded pipeline.”
Kinder Morgan says that for almost 60 years, the 1,150-km Trans Mountain pipeline system has been safely and efficiently providing the only west coast access for Canadian oil products, including about 90 percent of the gasoline supplied to the interior and south coast of British Columbia.
Last June, Kinder Morgan also proposed the building of second pipeline from the bitumen sands to the west coast, roughly following the route of the Northern Gateway pipeline to Kitimat. There was no mention of that project in today’s announcement.
