Benthic silicon fluxes and sediment porewater chemistry in Sheldon Cove, Borgen Bay and Marian Cove, West Antarctic Peninsula, in January 2020

This data product comprises 5 documents outlining biogeochemical data from three fjords along the West Antarctic Peninsula: Sheldon Cove (Adelaide Island), Borgen Bay (Anvers Island), and Marian Cove (King George Island). Data was collected in January 2020 on cruise JR19002 on the RRS James Clarke Ross. The project aimed at understanding the benthic release of dissolved silicon, a vital nutrient for phytoplankton in the Southern Ocean, in Antarctic fjords exposed to various degrees of glacier retreat. Data include elemental chemistry of porewater from inner and outer fjord in each bay, silicon isotopic composition of the porewater, dissolved inorganic nutrient concentrations in porewaters and the overlying seawater, and the diffusive benthic silica flux from the sediments.
