Plankton in the new millennium: keynote lecture at the 2022 ICES Decadal Symposium
Recent changes in oceanic plankton are being reported at unprecedented rates. Most changes are related to environmental factors and many were identified as driven by climate, either through natural cycles or by anthropogenic effects. However, the separation of both effects is difficult because of the small size of most observational series. Moreover, some changes are related to trends and cycles while others were perceived as abrupt ecosystem shifts, often synchronized over large spatial scales.
As part of the activities of The Fourth Symposium on Decadal Variability of the North Atlantic and
its Marine Ecosystems: 2010–2019 (https://decadal2022.imr.no/), from
20–22 June 2022 in Bergen, Norway,
opened Theme Session 2 (Decadal change and trends in North Atlantic/sub‐Arctic plankton and their ecosystems) with a keynote lecture entitled "Plankton in the new millennium: synchronic multidecadal trends and regime shifts".
