Nansen Legacy scientists were strongly represented at the 18th Russian-Norwegian Symposium in Murmansk 5-7 June 2018. The topic of the symposium was highly relevant for the Nansen Legacy project, by addressing the influence of ecosystem changes on harvestable resources in high latitudes. The symposium is an important forum for Norwegian and Russian scientists working on the same topics to meet, exchange ideas and learn from each other. As one of the Norwegian contributions, Leif Chr. Stige presented preliminary findings from the Nansen Legacy project, on how climate affects zooplankton species composition in the northern Barents Sea according to the time series available to date.
