US: Ecosystem reports show continuing effects of warming in Alaska’s marine waters

Published 2023년 12월 27일

Tridge summary

Alaska's Aleutian Islands experienced the warmest winter temperatures in over a century, while other areas like the Bering Sea and Gulf of Alaska are recovering from extreme marine heatwaves and temperatures have returned to more normal levels. The record-high temperatures in the Aleutians persisted for the rest of the year, impacting marine ecosystems and vulnerable species like Pacific cod and Atka mackerel. Warming temperatures are causing shifts in phytoplankton blooms that favor pelagic species, and the warming climate and ecosystem conditions in Alaska are impacting commercial fishing and seafood harvests.

The waters off Alaska’s Aleutian Islands registered the warmest winter temperatures in over a century, part of a decade-long period of warming, according to a report issued by the National Oceanic and Atmospheric Administration. The record-high temperatures in the western and central Aleutians moderated later in the year but warmer-than-normal conditions persisted for the rest of the year throughout the waters around the 1,100-mile chain extending from southwestern Alaska, according to the 2023 NOAA Fisheries Ecosystem Status report for the region. The Aleutians report is one of three annual ecosystem status reports issued by NOAA Fisheries for marine areas of Alaska. The reports, compiled by large teams of scientists, were released earlier this month and presented to the North Pacific Fishery Management Council, the panel that sets regulated commercial fishing in federal waters off Alaska. The annual reports provide snapshots of current conditions and clues about future ...
