| Summary: | The ICES Working Group on integrated assessments for the Norwegian Sea (WGINOR) synthe-sizes and evaluates information on physical, chemical, ecological, human, and environmental processes affecting the Norwegian Sea ecosystem. For this purpose, it gathers information, per-forms 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 2022, WGINOR reports that 1) while the extent of Arctic Water is increasing, the temperature of the Atlantic inflow has been close to the long-term mean, 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, measured since 1995, declined in the mid-2000s and has since remained relatively stable, 4) Norwegian spring-spawning herring and mackerel mature bio-masses declined slightly in 2022. After a few years of decline, ... |
