New York was once home to abundant marine life. When Henry Hudson sailed into the harbor in 1609, it contained an estimated 350 square miles of oyster reefs, which served as a natural water filter, storm barrier and commercial resource.
The U.S. Fish and Wildlife Service says Pacific walruses have begun coming ashore along Alaska’s northwest coast, and it’s likely because sea ice in the Arctic Ocean already has receded beyond the outer continental shelf.
While millions of people will be looking up to witness the solar eclipse this Monday, some will be monitoring the ocean for its effects on what an Oregon researcher calls the “largest mass migration on the planet”, among other things. KLCC’s Brian Bull reports.
Shy of 3 inches with skin in muddy shades of red, green or brown, the foothill yellow-legged frog is unremarkable at first glance. Flipping it over, however, reveals the signature gold shading of its legs and lower abdomen that leads some to exclaim its beauty.
A study published Wednesday by researchers at UC Davis may have major conservation implications for salmon in California and the Pacific Northwest. The study provides new evidence that “springers” and other salmon that migrate upstream from the ocean to spawn early in the year are genetically different than later migrating populations.
A dismal salmon run in the Klamath River has forced the Yurok Tribe — which normally catches its salmon from the Klamath River — to purchase the fish from an outside source for its annual Salmon Festival on Saturday.
President Donald Trump said Tuesday he has signed a new executive order intended to make more efficient the federal permitting process for construction of transportation, water and other infrastructure projects without harming the environment.

The Associated Press was joining international researchers on a month-long, 10,000 kilometer (6,200-mile) journey to document the impact of climate change on the forbidding ice and frigid waters of the Far North.
The state Department of Water Resources is beginning to lay the gravel foundation for spawning salmon. This comes as much of the gravel was washed away with high flows from the Oroville Dam spillway this winter.
A $914 million plan to expand the Los Vaqueros Reservoir as drought insurance for millions of Bay Area residents picked up endorsements Monday from six conservation groups in a rare display of environmental support for new water development.
The [Santa Ana] river bottom area — considered a wildlife preserve — is owned by the California Department of Fish and Wildlife, though the Riverside County Parks Department manages its water quality and habitat.
Given the long-term trajectory of the population and climate predictions for California, maintaining Delta smelt in the Delta for the next 20-30 years is not likely to happen without significant improvements to the habitat. So, what happens to the remaining smelt when they encounter California WaterFix?
Four environmental groups have faulted proposed state rules for commercial cannabis cultivation for failing to protect imperiled species, including the reclusive Pacific fisher, from rodent poison frequently used at unregulated grow sites.
Scores of convulsing sea lions are washing up on Central California beaches after eating fish poisoned by a plume of toxic algae that could spread north toward the Bay Area and cause widespread problems, marine biologists said.
Tuna caught in industrialized areas of the Pacific and Atlantic oceans have 36 times more pollutants than those fished in remote parts of the West Pacific, scientists from Scripps Oceanography have found.
The fate of the Northwest salmon may be decided by the way you use your heater and your air conditioner. In the near future, the U.S. electric grid will be able to digitally manage the vast Northwest hydroelectric network in a way unimaginable just a few years ago.
Rejecting a petition from environmental groups, the Trump administration announced Monday that it will not list Pacific bluefin tuna — a torpedo-shaped fish that can grow to 1,000 pounds and which sells for $100,000 or more per fish in Japanese sushi markets — as endangered, despite that fact that the animal’s population has fallen 97 percent.
The Interior Department has unveiled a plan to protect the threatened sage grouse that gives Western states greater flexibility to allow mining, logging and other economic development where it now is prohibited.
