Vertical distributions of macromolecular composition of particulate organic matter in the water column of the Amundsen Sea Polynya during the summer in 2014

Macromolecular compositions (carbohydrates, proteins, and lipids) of particulate organic matter (POM) are crucial as a basic marine food quality. To date, however, one investigation (Kim et al., 2016) has been carried out in the Amundsen Sea which is one of the fastest warming locations in the Southern Ocean. Water samples for macromolecular compositions were obtained at selected 7 stations in the Amundsen Sea Polynya (AP) during the austral summer in 2014 to investigate vertical characteristics of POM.
(1) to investigate the macromolecular compositions (proteins, lipids, and carbohydrates) and the fate of POM between in the photic and aphotic layers and (2) estimate physiological status and nutritional condition of phytoplankton as a major source of POM in the AP.
