During the JR19002 Icebergs 3 cruise, samples from the surface seawater were collected from Zodiacs. Samples were collected with the motivation of determining the impact of retreating glaciers upon the surface ocean, such as the hydrography and biogeochemical composition of the surface ocean. 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. Small boat traversed each bay, collecting particulate and dissolved seawater samples. Parameters collected and determined include: stable oxygen isotopes, salinity, dissolved macronutrients, dissolved and particulate metals, radium and thorium activity.
