By analyzing 42 years worth of canned salmon, University of Washington scientists show that levels a common marine parasite rose in two salmon species in the Gulf of Alaska from 1979 to 2021. The rise may be a sign of ecosystem recovery, possibly influenced by the 1972 Marine Mammal Protection Act.

Could Climate Change be Altering the Marine Food Web?
Research by scientists at Stony Brook University’s School of Marine and Atmospheric Sciences (SoMAS) reveals that climate velocity is affecting where large marine mammals are distributed relative to their prey species, which could have important implications for marine food web dynamics.
Nuclear War Could Trigger Big El Niño and Decrease Seafood
A nuclear war could trigger an unprecedented El Niño-like warming episode in the equatorial Pacific Ocean, slashing algal populations by 40 percent and likely lowering the fish catch, according to a Rutgers-led study. The research, published in the journal Communications Earth & Environment, shows that turning to the oceans for food if land-based farming fails after a nuclear war is unlikely to be a successful strategy – at least in the equatorial Pacific.
Atmospheric Rivers Help Create Massive Holes in Antarctic Sea Ice
Warm, moist rivers of air in Antarctica play a key role in creating massive holes in sea ice in the Weddell Sea and may influence ocean conditions around the vast continent as well as climate change, according to Rutgers co-authored research. Scientists studied the role of long, intense plumes of warm, moist air – known as atmospheric rivers – in creating enormous openings in sea ice. They focused on the Weddell Sea region of the Southern Ocean near Antarctica, where these sea ice holes (called polynyas) infrequently develop during the winter.
