Marine snow fuels life on the sea-floor

City-sized maps of terrain and life on the sea-floor have revealed that drifts of ‘marine snow’ on submarine hillsides act as a source of food to fuel a higher biomass of marine life on the hills than on the flatter plains surrounding hills This finding comes from research that may help improve understanding of how features, like hillside slopes and plateaus, add complexity to seafloor habitats and help drive the distribution of marine life.
