Analysis of sediment traps and Conductivity-Temperature-Depth (CTD) casts in Ryder and Marguerite Bay, Antarctica


Sediment traps were deployed and recovered and CTD/rosette casts were taken at two sites, one in Ryder Bay and one in Marguerite Bay. Biogeochemical proxy signals of nutrients and organic matter were assessed in sea ice compared to the open water column. The flux of this material in time series sediment traps located to two depths below the sampling site was also followed. Past changes in these proxy signals in Ryder Bay were also investigated from box core material taken from the study site.
