Description
Summary:"A high-resolution study of the early- to late-summer progression in primary production and carbon export potential in the Atlantic Southern Ocean" is the Honours thesis of Amelia Deary, focusing on the switch from new- to regenerated production in the framework of the new production paradigm as defined by Dugdale and Goering (1967). As a consequence of the paucity of seasonally-resolved NPP and N uptake data for the Southern Ocean, many dynamics of biological C and N cycling are difficult to disentangle. Sampling at the beginning and end of a single growing season thus makes this study unique. Rates (bulk and size-fractionated) of net primary production (NPP) and N uptake (as NO 3 - and NH 4 + ) were measured across the Atlantic Southern Ocean in early- (December) and late-summer (March) of the same year to investigate the evolution and drivers of phytoplankton N uptake dynamics and C export potential over the growing season.
