AMT19 (JC039) Primary Production (Size-fractionated) incubations using 14C uptake from CTD bottle samples.

Integrated size-fractionated primary production was measured throughout the photic zone (6 depths) at 38 stations across the North and South Atlantic (49 34.0N 08 38.01W; 39 18.9S 43 23.5W) between the 14th October and 25th November, 2009. These core measurements contribute to the unique time series of spatially extensive and internally consistent observations on the structure and biogeochemical properties of planktonic ecosystems in the Atlantic Ocean and the methods used are synonymous to those used on previous AMT cruises.
