A study @commsearth.nature.com report on trawling and fisheries echosounder surveys in the central #Arctic Ocean. Very little pelagic fish observed and none caught between 82N and the #NorthPole. In contrast to catches in the warmer Atlantic waters near #Svalbard. See: www.nature.com/articles/s43...

New study in @commsearth.nature.com highlights how #Arctic sea-ice ridges are biological hotspots in summer. Nearly 80% of ice algae biomass could then be in ridges. They've largely gone undetected because ridges are very seldom studied. Data was collected during the @awi.de MOSAiC expedition.
