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.

|Data Collection:||A set of moorings was deployed in Marguerite Bay in January 2005 from the British Antarctic Survey vessel RRS James Clark Ross. The bottles were pre-loaded with 2% buffered formalin to preserve organic material. The sediment trap bottles were recovered the following year and stored at 4C.|
