The Institute of Marine Research is hosting the conference «The Symposium on Decadal Variability of the North Atlantic and its Marine Ecosystems: 2010–2019». This is the 4th in a series of decadal symposia organized by ICES and NAFO.


Climate variability and change is impacting the distributions and productivity of marine species in the North Atlantic. The ocean is undergoing changes at multiple spatial and temporal scales, both naturally and because of anthropogenic pressure. However, detection of these changes often requires comprehensive analysis of ocean observations over long (e.g. decadal) time periods. Assessment of long-term patterns are critical for ocean resource management in order to predict the consequences of the changing ocean on the distribution of habitats and biodiversity.

Key challenge of the symposium

To summarize and explain the hydro-biological variability observed during the decade of 2010–2019 in relation to longer time variability or change, and to quantify the interactions between the variability and change in the ocean environment with variability in plankton, fish, mammals and seabirds in the north Atlantic marine ecosystems.

Scientific Programme

The symposium will provide new insight into the importance of climate in regulating marine ecosystems of the North Atlantic compared with other drivers of variability. The symposium will run as a single multidisciplinary session organized by four science areas; each session will include keynote presentations as well as contributed talks and posters. The science programme will offer opportunities for colleagues to share observations of variability at all trophic levels, ranging from physics to people, including ocean climate/physics, plankton, fish stocks, marine mammals, seabirds, and human impacts.

Programme 19–22 June 2022
