December 28, 2023 — 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.
