Dissolved organic carbon data for surface seawater and the sediment-seawater interface collected from the West Antarctic Peninsula during the Icebergs 3 JR19002 expedition in January 2020

During the JR19002 Icebergs 3 cruise, dissolved organic carbon samples from the surface seawater were collected from Zodiacs, and samples from the sediment-seawater boundary were collected from the CTD rosette. Samples were collected with the motivation of sampling glacially-derived material and determining the biogeochemical composition and environmental significance with respect to iron and carbon cycling. Three main sites were visited during JR19002 from south to north: Marian Cove, Maxwell Bay, King George Island; Borgen Bay, Anvers Island; and Sheldon Cove, Ryder Bay, Adelaide Island. Funding: NERC grants, NE/P017630/1 (Dr Amber Annett) and NE/P003060/1 (Professor David Barnes).
