Abstract:Particulate organic matter (POM) is considered the primary source of N and C in the ocean. In pelagic marine environments, POM consists of algae and detrital nitrogen, with amino acids representing the largest chemical fraction. Currently, measurements of the isotopic distributions of N atoms in amino acids are considered powerful tools for exploring and determining the metabolic sources involved in the synthesis and degradation of organic matter. In this study, we measured the δ15N of amino acid signatures (δ… Show more
