Scientist Rod Towell has been part of the fur seal counts since 1992. He said the difference at the rookeries is striking. Northern fur seal pup production has hit its lowest level since 1915.

Heavy snows over the weekend are likely to have saved up to half of the rare, endangered Saimaa seal pups being born this winter season from death by exposure or from predators.

The notoriously difficult-to-study Pacific walrus population decreased by about half between 1981 and 1999, likely due to hunting and changes to sea-ice habitat, according to a new USGS study that is considered the most up-to-date and comprehensive so far. The Pacific walrus is being considered for Endangered Species Act protections.

Over the past few months, a massive toxic bloom of the marine diatom Pseudo-nitzschia, stretching from central California to the Alaska Peninsula, has resulted in significant impacts to coastal resources and marine life. NOAA has been working closely with federal, state, tribal, academic, and other partners to respond to this unprecedented harmful algal bloom (HAB).

In January, 29 sperm whales were found stranded on shores around the North Sea, an area that is too shallow for the marine wildlife. Only recently were details of the animals’ necropsy released. However, scientists were deeply disturbed by what they found in the animals’ stomachs.
