Summary: A drifting sediment-trap array was deployed to investigate the flux of natural particulate materials from Weddell Sea summer surface waters. This array was launched, tracked, and recovered from the ice-escort vessel Maersk Master. This paper describes the field program and archives data on the geochemical and biochemical constituents of the material that was trapped. Mass fluxes out of the upper 100 m averaged 12 mg/sq m/hr, with the highest fluxes trapped near Site 695 (90 mg/sq m/hr). The trapped material was mostly flocculate in appearance, with microplankton assemblages dominated by diatoms of the genera Nitzschia and Thalassiosira and by the foraminifer Neogloboquadrina pachyderma. The material averaged 28% biogenic silica by weight; the organic portion was rich in amino acids, with average organic carbon/organic nitrogen ratio (by moles) of 7. Organic carbon isotopic fractionation (deltaC-13) ranged from -27 to -31; that of organic nitrogen (deltaN-15) ranged from -2 to +7. (Auth.)
