Global patterns in oceanic planktonic metabolism
Rates of gross primary production (GPP) and respiration (CR) of plankton communities in the upper ocean were evaluated on the basis of a data set comprising 3149 paired light and dark bottle measurements of volumetric GPP‐CR of euphotic zone plankton communities. The data were from 72 published and...
