Depth profiles of amino-acids in porewater of sediments from the Norwegian - Greenland sea

Dissolved free amino acids (DFAA) and dissolved combined amino acids (DCAA) were determined in the porewater of sediment cores from the Norwegian-Greenland Sea (water depth from 1000 to 3300 m). Concentrations in the sediment column were generally found to decrease with depth. The amino acid composi...
