NERC EDS UK Polar Data Centre. https://doi.org/10.5285/6a5a80f9-4c30-4ad6-a5be-ccba53f8a464 Results of sediment trap analysis conducted by British Antarctic Survey, University of Edinburgh and University of Bristol. Abundances and biovolume of intact phytoplankton and microzooplankton cells observed in sediment trap samples are presented. Data from two sediment traps deployed in the Scotia Sea, Southern Ocean, are presented (shallow=400 m, and deep = 2000 m). 4 samples were analysed from each, two in January/February 2018, and two in December 2018. Each sediment trap sample was split into multiple fractions to facilitate this and other analyses. Data facilitate the understanding of the magnitude and drivers of particulate fluxes in the Scotia Sea, Southern Ocean.

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 analysis of the phytoplankton and microzooplankton community composition from 8 samples, 4 from each sediment trap. Phytoplankton and microzooplankton enumeration was carried out under the light microscope, and the size of 10 random individuals for each species measured for biovolume calculations of phytoplankton only. Cells were determined as "full" or alive at time of collection if they possessed chloroplasts/plastids, pigment, a nucleus or, in the case of Pronoctiluca, a distinct accumulation body; cells lacking these internal features were deemed as "empty", or dead at time of collection. For full details of laboratory analyses of these splits, see Belcher et al. in review. Data collection: Sample collection: McLane PARFLUX Sediment Trap Sample splitting: McLane Sample Splitter Sample analysis: Light Microscope Data quality: 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. Only complete cells were enumerated to avoid over counting of fragmented specimens. For the larger, easily identifiable cells, the whole chamber was observed; for smaller cells a proportion of the chamber was examined depending upon cell abundance (at least 500 cells were counted). Biovolume calculations were made based on the metrics of 10 randomly selected specimens. Biovolumes of microzooplankton were not measured. asNeeded completed
