How salmon can transform a landscape

11/29/2019

BBC News

Protecting salmon in coastal Canada could have benefits that extend beyond the water they swim in and can have profound impacts on the surrounding landscape.

Skeins of wispy clouds obscure the tops of distant forested mountains, reflected in calm waters. On this midsummer morning at least, the Pacific is living up to its name on this stretch of Canada’s west coast. Backpacks and thermoses in hand, four researchers tread down a wooden strutted ramp to board a boat named the Keta. Scientist Allison Dennert starts the boat, steering away from the dock into the broad channel, glancing at the map on the video console. A brief stop at the Bella Bella dock, to pick up research technician Sarah Humchitt, completes our crew of five.

How the internet travels across oceans — a lot of cable laid very, very slowly

Like a freeway for all, companies typically pooled resources to lay the many thousands of miles of undersea cables that support global communications. Now, Google is going its own way to connect the United States to its data center in Chile.

Washington state to regulate federal dams on Columbia, Snake to cool hot water, aid salmon

1/31/2019

Seattle Times

Dams and climate change are the leading cause of high temperatures in the Columbia and Snake rivers that are killing salmon, according to an EPA draft analysis. Now the state wants to get involved.

Summer temperatures in portions of the Columbia and Snake rivers are up by 1.5 degrees Celsius since 1960 because of the combined effects of climate change and dams, according to a new draft analysis by the U.S. Environmental Protection Agency (EPA).

Underwater sensors for monitoring sea life (and where to find them)

Paul Gibbs, a mechanical engineer at the UW’s Applied Physics Laboratory, inspects the newest Adaptable Monitoring Package, or AMP, before a test in a saltwater pool. AMPs host a series of sensors that allow researchers to continuously monitor animals underwater.

Harvesting power from the ocean, through spinning underwater turbines or bobbing wave-energy converters, is an emerging frontier in renewable energy.

New tool lets citizens help reveal toxic cause of salmon death

Big ships asked to slow down to reduce noise for iconic whales

7/18/2017

Alaska Public Media-

If you think trying to carry on a conversation in a noisy restaurant or bar is difficult, imagine how whales in the noisy waters of the Salish Sea feel. Whale scientists think rising levels of underwater noise are having a harmful effect on the Northwest’s iconic killer whales. Now the Port of Vancouver, in British Columbia, is spearheading an experiment to temporarily slow down big ships to reduce noise.

Seattle seawall’s novel fish features are a potential model for the world

As tourists and residents visit Seattle’s downtown waterfront, it may not be immediately apparent they are walking on arguably the largest, most ambitious urban seawall project in the world that prioritizes habitat for young fish and the invertebrates they feed on.

Where are the kokanee? Only 60 to 70 fish counted in local creeks compared to nearly 6,000 a year ago

The Issaquah Press ~

Before emerging from the creek on a cold, sunny December morning, Dan Lantz pulled out a notebook to record a very familiar number this kokanee spawning season — zero.

Lantz, an environmental scientist for King County, and other fish ecologists were expecting a low return of kokanee this year. Spawning runs are typically cyclical, with boom and bust years. But nobody expected the numbers to be this bad.

Ruling forces discussions on breaching Snake River dams to save salmon

SPOKANE, Wash. — A federal judge is forcing discussion of a radical step to save endangered salmon: taking out four dams on the Lower Snake River.

The public will get a chance to weigh in at meetings throughout the Northwest starting next month.

"Scientists tell us that removing the four Lower Snake dams is the single most important action we could take to restore salmon in the entire Columbia-Snake river basin," said Sam Mace of Save Our Wild Salmon.
