For another, food is harder to come by. The central Arctic Ocean is largely covered with ice and – unlike the Antarctic’s Southern Ocean – surrounded by landmasses. Exchanges with the Atlantic [...] place via two comparatively narrow passages. As a result, the Arctic Ocean is an extremely nutrient-poor one, where less algae grows than in the waters of the temperate latitudes – which also means

Head of Group Dr. Doreen Kohlbach Further members of [...] Previous research suggests that pelagic food webs in the Central Arctic Ocean (CAO) are highly dependent on ice-associated food sources (Fig. 1), but how prevailing trophic structures will change with [...] traffic will bring more anthropogenic pollutants, even to remote Arctic regions, where they are entrained in water and sea ice, and transferred along the marine food chain.
