原始语种摘要: Recent Arctic studies suggest that sea ice decline and permafrostthawing will affect phytoplankton dynamics and stimulate heterotrophiccommunities. However, in what way the plankton composition will change as thewarming proceeds remains elusive. Here we investigate the chemical signatureof the plankton-dominated fraction of particulate organic matter (POM) collected along the Siberian Shelf. POM(> 10 µm) samples were analysed using molecularbiomarkers (CuO oxidation and IP25) and dual-carbon isotopes( δ 13C and Δ14C). In addition, surface water chemicalproperties were integrated with the POM (> 10 µm)dataset to understand the link between plankton composition and environmentalconditions. δ 13C and Δ14C exhibited a large variability in...
