WASHINGTON: Seattle Harbor Expansion Would Push Out Endangered Whales, Conservation Group Says

March 5, 2021 — The Trump administration rushed through a project to expand Seattle Harbor for ultra-large container ships that would further threaten endangered Southern Resident killer whales, according to a lawsuit filed Thursday.

Only 75 Southern Resident killer whales swim the Salish Sea — a number that has increased since three baby whales were born in the relatively quiet waters of the pandemic. Noise from whale watching boats and ships headed to and from ports across the Pacific will increase when pandemic restrictions are lifted.

Added to that is a new worry: the underwater cacophony of ultra-large container ships that would visit Seattle Harbor, in the heart of the whales’ home waters, and the release of hundreds of thousands of cubic yards of toxic material dredged during the harbor project.

The three pods, or family lines, of Southern Residents took a major hit in the late 1960s when aquariums stole 45 Southern Residents from their families, and killed another 14 in the process. Only one of the whales taken during that time survives today: a 53-year-old whale who lives at the Miami Seaquarium. The Seaquarium calls her Lolita, while supporters who want her returned to a protected cove of the Salish Sea call her Tokitae.

CALIFORNIA: The San Francisco Bay Once Teemed With Oysters. What Happened?

March 5, 2021 — Oysters are a controversial food.

Some people slurp them down by the dozen, while others would rather go hungry for days than be forced to eat a single slimy specimen.

As one KQED staffer put it: “No matter how fresh they are, no matter where they come from, no matter what is put on them, it reminds me of being congested and having snot just slide down my throat.”

Bay Curious listener Joseph Fletcher falls into the first category: The San Francisco resident loves oysters and has been wondering if he’ll ever get the chance to eat one grown in San Francisco Bay.

“Will oysters ever make a comeback in the bay and return to the numbers they had back in the days before the Gold Rush?” Fletcher wanted to know.

There’s one type of oyster that’s indigenous to the San Francisco Bay, and that’s the Olympia oyster (Ostrea lurida). It’s named after Olympia, Washington, though these small, tangy oysters can be found up and down the west coast from Alaska all the way down into central Mexico.

Study: Chinook salmon are key to Northwest orcas all year

March 4, 2021 — For more than a decade, Brad Hanson and other researchers have tailed the Pacific Northwest’s endangered killer whales in a hard-sided inflatable boat, leaning over the edge with a standard pool skimmer to collect clues to their diet: bits of orca poop floating on the water, or fish scales sparkling just below the surface.

Their work established years ago that the whales depend heavily on depleted runs of Chinook, the largest and fattiest of Pacific salmon species, when they forage in the summer in the inland waters between Washington state and British Columbia.

But a new paper from Hanson and others at the NOAA Fisheries Northwest Fisheries Science Center provides the first real look at what the whales eat the rest of the year, when they cruise the outer Pacific Coast — data that reaffirms the central importance of Chinook to the whales and the importance of recovering Chinook populations to save the beloved mammals.

By analyzing the DNA of orca feces as well as salmon scales and other remains after the whales have devoured the fish, the researchers demonstrated that the while the whales sometimes eat other species, including halibut, lingcod and steelhead, they depend most on Chinook. And they consumed the big salmon from a wide range of sources — from those that spawn in California’s Sacramento River all the way to the Taku River in northern British Columbia.

Salmon Conservation Key to Saving Killer Whales

March 4, 2021 — The endangered Southern Resident killer whales in the waters near Washington and British Columbia have stalled in their population recovery, and, according to new research, a major factor limiting their growth is their preference for preying on Chinook salmon.

In a study published Wednesday in the journal PLOS One, researchers present new data on environmental stressors facing the orcas and propose investment in the conservation of Chinook salmon to aid in the recovery of the population.

Killer whales are some of the most recognizable mammals in our seas with their distinct black and white markings. While they can be found in every ocean, they have broken off into small populations, creating different sub-species known as transient, offshore, and resident. The three groups are unique to one another, with different physical attributes as well as social structures and behavioral habits.

There are multiple populations of resident killer whales, but the authors of this study looked specifically at Southern Resident killer whales. These orcas mostly inhabit the waters around Oregon, Washington and British Columbia, and make up the smallest of the resident populations.

OSU researcher leads NOAA-funded project to study West Coast response to ocean acidification

March 4, 2021 — The following was released by Oregon State University:

An Oregon State University researcher is part of a new federally supported project investigating how communities along the West Coast are adapting to ocean acidification, with the goal of determining what they need to be more resilient.

Ana K. Spalding, an assistant professor of marine and coastal policy in OSU’s College of Liberal Arts, is leading a team looking into how shellfish industry participants in several towns along the Oregon and California coasts are responding to ocean acidification and where gaps in policy or resources have left them vulnerable.

The $1 million, three-year interdisciplinary project is funded by the National Oceanic and Atmospheric Administration (NOAA) through its Ocean Acidification Program. At OSU, Spalding is working with Erika Wolters, assistant professor of public policy, and Master of Public Policy students Victoria Moreno, Emily Griffith and Ryan Hasert.

“The goal of this project is to better align policy responses with the immediate and very local needs of shellfish-reliant communities,” Spalding said. “This is both understanding that vulnerability and proactively thinking, ‘What can we do to respond to better support members of the shellfish industry and their needs?’”

Ocean acidification and its impact on shellfish first became a major concern for West Coast farmers after a 2007 mass oyster larvae die-off at the Whiskey Creek Shellfish Hatchery in Netarts Bay, Oregon. OSU scientists definitively linked that die-off to increased carbon dioxide in the water in a 2012 study.

WASHINGTON: NOAA’s Mukilteo waterfront fish lab won’t be rebuilt

February 25, 2021 — That waterfront is losing more than an important eyesore.

Plans were scrapped when bids came in too high for a new Mukilteo Research Station to replace the weathered two-story hovel where scientists studied climate change effects, ocean acidification and impacts on fish health.

“We sought contractor bids to rebuild the facility on-site. Unfortunately, the bids greatly exceeded the funds available for the project,” Michael Milstein, a spokesperson for the National Oceanic and Atmospheric Administration, said Wednesday. He would not give any bid figures.

The future of the 1.1-acre federal property on Front Street is uncertain. It could possibly end up in private hands and become condos or a parking lot.

Warming seas could wipe out Snake River chinook by 2060, scientists predict

February 19, 2021 — Snake River spring-summer chinook could be nearly extinct by 2060 and interventions are “desperately needed” to boost survival in every stage of their lives, scientists warn.

The findings, published Thursday in the journal Communications Biology, modeled survival of eight populations of wild Snake River Basin spring-summer chinook during the ocean phase of their life, under various climate-warming scenarios.

Salmon hatch in rivers, but mature for years at sea before they return to the waters of their birth. It is a perilous life cycle that could become all but impossible for some already fragile salmon populations that make one of the most arduous of all journeys, all the way to Idaho. They travel more than 1,800 miles round trip, climb more than a mile in elevation, and tackle eight dams, each way: four on the main stem Columbia, then four more on the Lower Snake River.

Add just a little ocean warming, and it’s curtains. Populations declined in all eight basin chinook populations for which the scientists ran predictions. Just a little more than 1 degree Celsius temperature increase in sea-surface temperature produced dire effects — with mortality as high as 90% in warmer seas.
