Mass deaths of sea life in the N Pacific

I think that hypothermia is the LEAST likely cause of this phenomenon. Try a perfect storm of radiation, warm waters and acidification.

• A deadly patch of warm water along the American West Coast called the ‘Pacific blob’, stretching all the way from California up to the Gulf of Alaska, has killed literally billions of marine species and birds since around 2011.
• 300 tons of radioactive water leaking daily into the Pacific daily and no known technology to fix it.
• More signs indicate the Northwestern coast of Canada and the US is dying.
• Two thirds of animals expected to be extinct by 2020! 60 %

Hundreds of dead seabirds have been found washed ashore on sites from islands in the Bering Sea to villages north of the Bering Strait, signs of another large die-off in the warmed-up waters of the North Pacific Ocean. (The actual numbers will be in the thousands as most will die at sea.)

The dead birds are mostly northern fulmars and short-tailed shearwaters, species that migrate long distances to spend summers in waters off Alaska and other northern regions, the U.S. Fish and Wildlife Service reported.

Also in the mix are some kittiwakes, murres and auklets, the federal agency said.
The cause is being investigated.

Necropsies so far show that the birds are emaciated - with no food in their stomachs or intestines and little or no fat on their bodies.

"Right now, we know that they are starving to death and can't hold their heads above water, and they're drowning," said Ken Stenek, a teacher in Shishmaref and volunteer in a program that monitors seabirds.

The precise toll is unclear.

Fish and Wildlife said in its bulletin about 800 dead birds had been found since early August, but surveys are continuing and the known toll appears to be mounting - and experts caution that birds washing ashore represent only a small fraction of the dead.

Of this latest wave, the first was found on the Pribilof Islands in the Bering, the Fish and Wildlife Service said.

Since then, dead birds have washed ashore on Bering beaches and as far north as the Inupiat villages Shishmaref and Deering on the Chukchi Sea mainland coastline.

The new die-off follows a massive loss of common murres in 2015 and 2016, the biggest murre die-off on record in Alaska, and a precursor to near-total reproductive failures for murres in the Gulf of Alaska and Bering.

It also follows the deaths of hundred of puffins found last fall on St. Paul Island in the Pribilofs and, prior to that, mass deaths of murres and auklets along the U.S. West Coast.

In each death wave, starving birds have left emaciated carcasses, and each wave has been associated with unusually warm marine waters.

The Bering event is the latest in an "unprecedented series of marine bird die-offs" over the last four years in waters from California to the Arctic, said Julia Parrish, executive director of the Coastal Observation and Seabird Survey Team, or COASST, managed by the University of Washington.

It indicates that the pattern is moving north, said Parrish, a professor at the UW's School of Aquatic and Fishery Sciences.

"This just seems like the next chapter in the story," she said.

This is the fourth consecutive year when the Bering has been "exceedingly warm," said Rick Thoman, climate science and services manager for the National Weather Service in Alaska.

This year, early spring ice melt allowed open waters to begin absorbing heat early, Thoman said. "You had much longer for the water to get warmer this year," he said.

Stenek, who volunteers for COASST, said he and two other teachers found about 100 dead birds around Shishmaref.

The carcasses appear to be more plentiful on St. Lawrence Island in the Strait.
Surveyors have found about 500 dead birds near the St. Lawrence village of Gambell, Stenek said. He and his colleagues have found some birds alive but in very bad shape, he said.

That is similar to reports from elsewhere, Parrish said.

Birds found alive are "moribund" and being tossed around by the waves rolling ashore, she said. "They're kind of past the point of recovery," she said.

"They're so weak they can't hold their heads up."

Some carcasses have been examined at the U.S. Geological Survey's National Wildlife Health Center in Wisconsin, but results are inconclusive.

"We know that they're starving.

Their bodies are emaciated," said Robb Kaler, a biologist with Fish and Wildlife's migratory bird program.

What is causing the starvation is unknown, he said.

He had just packed up four additional fulmar carcasses Monday for express delivery to the Wisconsin centre.

"There's no sign of diseчase.

We will continue to test for that," Kaler said.

And investigations are continuing into possible links to toxins produced by harmful algal blooms, he said.

Parrish said the latest die-off has a few special chюracteristics.

The affected birds, northern fulmars and short-tailed shearwaters, "are different kinds of species than all the other die-offs that we have seen," she said.

They are long-distance migratory fliers, with the shearwaters coming from as far away as Australia, unlike murres, puffins and auklets, which winter in North Pacific waters.

Mass Death of Seabirds in Western U.S. 'Unprecedented' as tens of thousands dead due to deadly patch of warm water along the American West

2015 and 2016 were the two hottest years ever recorded; we should not be surprised therefore to find our oceans to be showing signs of stress as the delicately balanced eco system is also being stretched to its limit.

A deadly patch of warm water along the American West Coast called the ‘Pacific blob’, stretching all the way from California up to the Gulf of Alaska, Has killed thousands of California sea lions in 2015. Many starved as they struggled to find food in an unusually warm eastern Pacific. Strange exotic tropical fish have been reported off the coast of Alaska. In the winter of 2015 blue-footed diving seabirds called Cassin’s auklets, have been washing up dead by the thousands on beaches from San Francisco to Alaska, it is thought more than 250,000 died from lack of food. An unprecedented die off  which began in 2011 along the West coast of North America when billions of sea urchins and sea stars died suddenly in what was 'one of the most unusual and dramatic die-offs marine biologists have ever recorded.'

The Culprit: Warm Water?

Bill Sydeman, a senior scientist at California's Farallon Institute, said he believes the most likely scenario is that the deaths are related to a massive blob of warm water that heated the North Pacific last year and contributed to California's drought and to 2016 being the hottest year on record.

That water was hotter and stayed warm longer than at any time since record-keeping began. It stretched across the Gulf of Alaska, where a high-pressure system blocked storms, preventing the water from churning to the surface and mixing with air. More warm water eventually moved inward along the coast as far south as California, altering how favourable the environment was for the zooplankton that many fish and birds, including Cassin's auklets, feed on.

Last year tens of thousands of common murres were the victims, an abundant North Pacific seabird, starved and washed ashore on beaches from California to Alaska, researchers have pinned the cause to unusually warm ocean temperatures that affected the tiny fish they eat.

A year after tens of thousands of the common murres died, John Piatt, a research wildlife biologist for the U.S. Geological Survey claims the deaths of the common murres is an indicator of the regions' health.

Elevated temperatures in seawater affected wildlife in a pair of major marine ecosystems along the West Coast and Canada, said

"If tens of thousands of them are dying, it's because there's no fish out there, anywhere, over a very large area," Piatt said.

It is thought 500,000 of the common murres, who look like thin penguins, died last year all though this could be just a conservative guess because only a fraction of the dead birds likely reached the shore.
