The Working Group on Integrated Assessment of the North Sea (WGINOSE) aims to provide a holistic analysis of the present and future status of the North Sea Ecosystem and human activities therein. Analyses are split among 14 strata since the North Sea is a diverse ecosystem spanning the shallows of the Southern North Sea banks to the deeps of the Norwegian Trench. State-ofthe-art statistical methods for trend analysis were performed on time-series data spanning 35 years (1984-2019) which show a flat (constant) or downward (declining) trend in all strata for cod, herring and haddock abundance, a consistent upward (rising) trend for temperature and dissolved oxygen, while other fish species and oceanographic variables show both upward, downward or flat trends.
