Active mesopelagic prokaryotes support high respiration in the subtropical northeast Atlantic Ocean
Here we provide evidence, based on prokaryote metabolic proxies and direct estimates of oxygen consumption, that the mesopelagic prokaryote assemblage in the subtropical Northeast Atlantic is an active one. It supports a high respiration (0.22 ± 0.05 μmol O2 1-1 d-1, corresponding to 68 ± 8 mmol CO2...
