Active and passive organic carbon fluxes during a bloom in the Southern Ocean (South Georgia).

The Controls Over Mesopelagic Interior Carbon Storage (COMICS) cruise DY086 took place aboard the RRS Discovery in the South Atlantic during November and December, 2017. Physical, chemical, biogeochemical and biological data were collected during three visits to ocean observatory station P3, off the coast of South Georgia, during an austral spring bloom. A diverse range of equipment including CTD-rosette, Acoustic Doppler Current Profiler (ADCP), net deployments, marine snow catchers (MSCs), Stand Alone Pump System (SAPS) and PELAGRA Sediment Traps were used to produce a comprehensive, high-quality dataset. The data can provide excellent insight into regional biological carbon pump (BCP) processes; it is recommended for use by observational scientists and modellers to enhance understanding of ecosystem interactions relating to mesopelagic carbon storage.
Competing Interests: Competing interests: The COMICS project (NERC NE/M020835/2) funded the data collection effort and data synthesis and submission was funded by the Sustainable Management of Mesopelagic Resources (SUMMER) project under grant agreement No 817806. The simultaenous glider mission was supported by a European Research Council Consolidator grant (GOCART, agreement number 724416) to S. Henson, as well as South Africa’s Department of Science and Innovation (DST/CON0182/2017) and the National Research Foundation (SANAP: SNA170522231782) grants; as such, these data are published separately. There is no conflict of interest in submitting this paper for consideration.
