Arctic basal resources and organisms measured with d13C values in essential amino acids ...

This data consists of compound specific isotope analysis of d13C values in essential amino acids measured in several Arctic basal resources collected in the field; ice algal filters, pelagic phytoplankton filters, kelp Laminaria digitata, red algae Coccotylus truncatus and Melosira arctica strands,...

Description
Summary:This data consists of compound specific isotope analysis of d13C values in essential amino acids measured in several Arctic basal resources collected in the field; ice algal filters, pelagic phytoplankton filters, kelp Laminaria digitata, red algae Coccotylus truncatus and Melosira arctica strands, and in cultures of fungi, bacteria, 2 pelagic phytoplankton, and 3 sea-ice algae species. See document for the different gears used, which include Surface Underwater Ice Trawl, Bottom trawl, Ice corer, and Niskin bottles. Field samples were collected on the Polarstern PS106.2 expedition from 23 June to July 2017 on the Barents Shelf and Nansen Basin. Cultured ice algae, pelagic phytoplankton, bacteria and fungi were almost all extracted from the Arctic region (see document). Isotopic measurements were done with a gas chromatograph isotope ratio mass spectrometer with methoxycarbonyl esterification of the amino acids in 2019. The aim of the measurements was to trace the d13C-EAA values of the Arctic basal resources ...
