Even brief exposures of the eggs of Atlantic haddock to low concentrations of dispersed crude oil can cause severe and usually deadly deformities in developing fish, an international research team has found.
In August 2016, NOAA and partners broke ground on the second-largest dam removal in California. The Benbow Dam, on the South Fork of the Eel River, is a safety hazard. It also limited salmon and steelhead from reaching their upstream habitat.
An international team of scientists who searched out specimens from museums and remote Arctic islands has identified genetic evidence of a rare new species of beaked whale ranging from northern Japan across the Pacific Ocean to Alaska’s Aleutian Islands.
An ecological experiment that employed beavers to restore streams in Central Oregon found that the streams produced nearly twice as many juvenile steelhead within a few years after the beavers went to work.
The new research found that the known climate patterns linked the tropical and temperate latitudes of the North Pacific Ocean, helping to fuel an extreme marine heatwave.
