flux in polar oceans In both Polar Regions, areas covered by sea ice are shrinking due to climate warming. What are the consequences of sea ice decline in the Arctic and the Antarctic Ocean? Answering this [...] and nature conservation in the Arctic and Antarctic Oceans under environmental change. The research project investigates ice-covered deep-sea ecosystems in the Arctic and Antarctic sea ice zones. Iceflux

Plastic particles are broken down in the ocean by sunlight [...] Climate change is especially putting the polar regions under pressure. Environmental changes in the Arctic result primarily from the decline in the area of sea ice and the decrease in its thickness, since
