BC orders Prince Rupert air shed study with wider scope than the Kitimat report

The province of British Columbia has posted a request for bids for an extensive air shed study for Prince Rupert, a study that has much wider scope that the controversial Kitimat air shed study. The maximum cost for the study is set at $500,000. The BC Bid site is asking for  a study of potential impacts to the environment and human health of air emissions from a range of existing and proposed industrial facilities in the Prince Rupert airshed, further referred to as Prince Rupert…

Ocean acidification growing risk to west coast fishery, including crab and salmon, US studies show

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…

Fossil hedgehog, tapir lived in ancient rain forest at threatened Driftwood Canyon Park near Smithers

About 52 million years ago what is now the Bulkley Valley was home to a tiny hedgehog  and an ancient ancestor of tapirs, who lived on the shores of a placid lake surrounded by  a lush upland forest. The newly discovered fossils at Driftwood Canyon near Smithers are significant advance in the study of the ancient history of the region. That’s because while the Driftwood Canyon Provincial Park is known for beautifully preserved fossils of leaves, fishes and insects, these are the first mammalian remains…

Rebar in hatcheries could distort navigation sense in young salmon and trout

Iron and steel in hatcheries, including rebar supporting concrete structural elements, could be distorting the ability of salmon and trout to navigate using the earth’s magnetic fields according to a study released today by Oregon State University. The exposure to iron and steel distorts the magnetic field around the young fish, affecting the fish’s “map sense” and their ability to navigate, said Nathan Putman, who led the study while working as a postdoctoral researcher in the Oregon Department of Fisheries and Wildlife, part of OSU’s…

US study finds shale development generally helps local government coffers with revenue gains offsetting costs

A study by Duke University of the US shale gas boom has found that oil and gas development from shale fields has generally helped the public finances of local communities, providing new revenues and resources that usually — but not always — outweigh the increased demand for public services and other costs. It found that many local governments in western North Dakota and eastern Montana, near the Bakken shale formation, have thus far experienced net negative fiscal effects. Also, some municipalities in rural parts of…

Harper’s Northern Gateway strategy and why it will end up in a muddy mess

It appears that the Stephen Harper’s strategy for approving Northern Gateway has been revealed on background to The Globe and Mail’s Gary Mason. (Either it’s a revelation or a trial balloon). 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…

Genetics show stronger pine beetle evolving; stream flow increases in infected forests: studies

A new study, based at the University of Alberta, released this week, indicates that natural selection may be making the mountain pine beetle more tolerant of colder temperatures and that the beetle may be evolving the ability to fly longer distances. A second study, from the Colorado School of Mines, also released this week, is tracking how the extent of pine beetle infected or killed trees in forests is changing ground water and stream flows. The mountain pine beetle infestation has wreaked havoc in North…

Using more wood for construction can slash global reliance on fossil fuels, Yale study says

Using more wood for construction of both buildings and bridges thus reducing the amount of steel and concrete would substantially reduce global carbon dioxide emissions and fossil fuel consumption, according to a Yale University study. The idea is that using wood would reduces the amount of energy required for steel and concrete and therefore greenhouse gases. The study says that sustainable management of wood resources would both allow proper management of forsests while also reducing fossil fuel burning. The results were published in the Journal of…

First Nations historical herring harvest offers “deep time perspective” to modern managers, SFU study says

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…

How oil spills kill fish: new study points to cardiac arrest; possible implications for humans

Oil spills kill fish. That’s well known. Now scientists say they have found out why oil spills kill adult fish. The chemicals in the oil often trigger an irregular heartbeat and cardiac arrest. A joint study by Stanford University and the US National Atmospheric and Oceanic Administration have discovered that crude oil interferes with fish heart cells. The toxic consequence is a slowed heart rate, reduced cardiac contractility and irregular heartbeats that can lead to cardiac arrest and sudden cardiac death. The study was published…
