Results of sediment trap analysis conducted by British Antarctic Survey, University of Edinburgh and University of Bristol. Particulate fluxes and isotopic compositions of particulate organic carbon, nitrogen and biogenic silica are presented. Data from two sediment traps deployed in the Scotia Sea, Southern Ocean, are presented (shallow=400m, and deep = 2000m), with 14 samples for each spread across the year 2018 to capture the seasonal cycle from January to December. Each sample was split into multiple fractions for these multiple analyses. Data facilitate the understanding of the magnitude and drivers of particulate fluxes in the Scotia Sea, Southern Ocean. Work funded by NC-ALI funding to the British Antarctic Survey Ecosystems programme.

Sediment traps were deployed in January 2018 aboard research cruise JR17002 and recovered in January 2019 aboard research cruise DY098. Each sediment trap collected 14 samples, open for periods of 7-31 days, which, on return to the laboratory were split into multiple aliquots for subsequent analysis. Splits were taken for particulate organic carbon (POC), particulate nitrogen (PN), biogenic silica (BSi, SiO2), as well as stable isotopes delta13CPOC, delta15NPN and delta 30SiBSi. For full details of laboratory analyses of these splits, see Belcher et al. in review. ...
