Amino acid and carbohydrate patterns across Fram Strait during POLARSTERN cruise PS107
Amino acids (AA) and carbohydrates (CHO) are produced by phytoplankton as part of the particulate organic carbon (POC) fraction, and can subsequently be released into the dissolved organic carbon (DOC) pool serving as food for heterotrophs. We investigated changes in quantity and quality of POC and...
