Amino acids (AA) and carbohydrates (CHO) are produced by phytoplankton as part of the particulate organic carbon (POC) fraction, and are subsequently consumed by smaller heterotrophs. We investigated changes in quantity and quality of individual AA and CHO in three size-fractions of POC (< 10 um, 0.7 - 10 um, 0.2 - 0.7 um) at three stations in the Fram Strait during annual Hausgarten sampling cruise PS107.
