The ICES Working Group on integrated assessments for the Norwegian Sea (WGINOR) synthesizes and evaluates information on physical, chemical, ecological, human, and environmental processes affecting the Norwegian Sea ecosystem. For this purpose, it gathers information, performs data analyses, and interacts with stakeholders. Based on these, WGINOR develops and produces an annual ecosystem status summary and assembles a knowledge base that supports the Norwegian Sea Ecosystem Overview. In 2023, WGINOR updated the integrated ecosystem assessment of the Norwegian Sea and reports that 1) while the extent of Arctic Water is increasing, the heat content in the Norwegian Sea remains above the long-term average, 2) the annual primary production remains stable, but the seasonal timing of peak production is gradually shifting to a later date, 3) zooplankton spring biomass declined in the mid-2000s and since then there has been no clear trend but variations between years, 4) spawning-stock biomass of herring and ...
