Temperature dependence of planktonic metabolism in the subtropical North Atlantic Ocean
The temperature dependence of planktonic metabolism in the subtropical North Atlantic Ocean was assessed on the basis of measurements of gross primary production (GPP), community respiration (CR) and net community production (NCP), as well as experimental assessments of the response of CR to tempera...
