English: Phytoplankton form the base of both marine and freshwater ecosystems, including that of the Arctic Ocean, and their abundance is strongly tied to the presence or absence of nutrients. According to a study focussed on the Arctic Ocean published in the Nature Communications scientific journal, more nutrients than was previously thought originate from continental sources. In particular, these nutrients stem from coastal erosion and river discharge, and not from the diminishing amounts of sea ice and changes in ocean circulation. This discovery suggests that, despite the climatic changes that affect ecosystems at high latitudes, fisheries of the Arctic Ocean will not experience major disruptions. This image, acquired by one of the Copernicus Sentinel-2 satellites on 27 July 2020, shows the delta of the Pechora River in Russia, one of the six major rivers that flow into the Arctic Ocean, and which were studied to achieve this important result. Data retrieved by the Copernicus Marine Environment Monitoring Service can be used to plan sustainable fishery activities.
