Method Primary source [16] abstract: "Here [investigator] use[s] an analysis of depth-integrated measures of production and respiration from five open-ocean regions to show that, in the upper 100 m of the water column, biological production generally exceeds consumption."
Comments P.379 right column top paragraph: "Rates of respiration in the surface layer of the ocean are typically high, with average values of about 1.2 g C/m^2/day (primary sources), which, if extrapolated over the 290×10^6 km^2 of the open ocean, represent a global respiration of about 143 Gt C/yr."
