Sediment trap fluxes and stable isotopes of particulate carbon, nitrogen and biogenic silica from the Scotia Sea in 2018
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=400 m, and deep = 2000 m), 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.

We note that the mooring itself experienced periods of higher flow in June 2018 and late August/September 2018 and thus particle collection may be biased at this time.
For each flux measurement, we present the maximum and minimum measurement resulting from analyses of 2 replicate splits (for a couple of samples, 3 replicates were measured, and again the maximum and minimum are given here).
Reproducibility of delta13Cpoc and delta15NPN is 0.2 per mille based on repeat measurements of analytical standards.
For delta 30Si, solutions were measured in replicate (n = 2-3) alongside continuous measurement of reference standards Diatomite and LMG-08 to ensure reproducibility and to monitor data quality. Measurements of Diatomite and LMG-08 yielded delta 30Si of +1.23 per mille (SD ± 0.03, n=18) and -3.40 per mille (SD ± 0.05, n=5) respectively, which agreed with published values. Typical reproducibility between the sample pseudo replicates was 0.04 per mille (1 x SD). Not all samples were able to be successfully analysed for delta 30SiBSi. and these are denoted by ND (=No Data).
