Soft sediment ecosystem functioning under climate projections at the Cape Verde Basin (North-East Atlantic)
Environmental conditions at the deep seafloor are projected to change under future climate scenarios, which in some cases can already be observed. With climate change, soft-sediment ecosystems are predicted to experience multiple stressors including deoxygenation, acidification, warming, and reduced...
