Ross Reynolds talks to writer Simon Winchester about his book "Pacific: Silicon Chips and Surfboards, Coral Reefs and Atom Bombs, Brutal Dictators and Fading Empires and the Coming Collision of the World's Superpowers." 

Would you be able to tell if the wild Alaskan sockeye salmon you ordered for dinner was swapped out for a less expensive piece of farm-raised salmon?

For the observant, the color difference between the two would likely be the first giveaway. (Sockeye has a deeper red-orange hue.) Or maybe you'd notice the disparity in the thickness of fillet. (Sockeye is flatter and less steaky in appearance.)

Killer whale biologists used a hexacopter drone last month to capture stunning, overhead photos of every single member of the endangered Puget Sound orca population.

David Hyde sits down with John Delaney, professor of oceanography at the University of Washington, to discuss what scientists are learning from a recent underwater volcano that erupted off the coast of Washington and Canada.

Christopher Clark, who directs the bioacoustics research program at Cornell University, is among the world's best scientific listeners. His work has revealed how human-made noise is filling the ocean, making it harder for marine animals to hear their own world. But Clark didn't start out with much interest in whales at all.

Call it “The Blob.”

It’s an unusually warm patch of water off the West Coast that has flummoxed climatologists.

“It’s still rearing its ugly head,” said Nick Bond, Washington state climatologist and regular contributor to KUOW. He first detected The Blob in 2013. 

This photo, taken last fall, is an indicator of things to come, according to scientists. The warm blob of water off the coast has conspired with low precipitation to amplify problems in Puget Sound. The result: more jellyfish.

Puget Sound is going through a lot of changes. And a trend we reported on earlier this year has accelerated: Salmon are losing while jellyfish are winning.

Little fish are disappearing from much of Puget Sound, according to a new study.

These are the fish that orcas and salmon depend on, and they’re being replaced by ballooning populations of jellyfish, which most fish and seabirds don't eat.

Oregon Scientists Lead Underwater Research

May 5, 2015

Last month Ed Dever helped to put four special, giant buoys off the coast of Oregon.

“I like to think of them as floating laboratories,” said Dever, who is an Oceanography professor at Oregon State University.

Each bouy is tethered to the ocean floor, weighs over 10,000 pounds, and is loaded with scientific instruments which will soon be measuring oxygen levels, acidity, and other biological and chemical data.

A ship full of marine scientists is floating over the deepest part of the world: the Pacific Ocean's Mariana Trench. They're sending down probes to study life in one of the most hostile environments on the planet.

This week the researchers are targeting the two deepest spots in the trench — the Sirena Deep and the Challenger Deep — which each extend down about 7 miles beneath the ocean's surface.

SEATTLE -- As the waters of the Pacific warm, methane that was trapped in crystalline form beneath the seabed is being released. And fast.

New modeling suggests that 4 million tons of this potent greenhouse gas have escaped since 1970 from the ocean depths off Washington's coast.

How Ocean Chemistry Threatens The NW Oyster Industry

Aug 12, 2014

NETARTS BAY, Ore. -- Mark Wiegardt steps slowly through knee-high water, pausing over some jagged lumps of brown-gray shells with a bent flat-head screwdriver.

He picks up a clumps of oysters and rests it on his thigh, stabbing and wrenching until the shellfish crack apart.

The creatures inside are more valuable than ever, so Wiegardt tries his best to make them look nice by bashing off the sharp edges.

What's Killing Clams? Solve This Low Tide Mystery

One of the lowest tides of the year this weekend revealed a "crime scene" at the beach at Golden Gardens Park in Seattle.

Combating Algae One Dollar At A Time

Jun 23, 2014

Millions of dollars in new funding to help combat harmful algae in Oregon and throughout the country are just a presidential pen stroke away.

Toxic algae blooms contributed to closing some of Oregon’s lake, ponds and reservoirs for a combined total of more than 700 days in 2013 alone.

A large swath of the Atlantic Ocean could soon be used to generate electricity, as a U.S. agency proposes opening more than 1,000 square miles of ocean to wind energy projects. The area is off the coast of Massachusetts, which has been working on the proposal with federal officials.
