Water samples were collected for chlorophyll and nutrient concentrations, biogenic and lithogenic silica concentrations, particulate organic carbon and nitrogen (POC/PON) concentrations, phytoplankton identification, Si, C, N, and Ge isotopes, particulate Ba, and other trace elements associated with suspended particles. Some samples were collected by small boat launched from Rothera research station and other seawater samples were collected from under the ice by divers. Water was also collected from RaTs (Rothera Oceanographic and Biological Time Series) CTD sites 1 and 2, and from Honeybucket (off Rothera Point). Brine was collected by drilling a hole, washing out and waiting for the hole to fill (sack-hole drilling). Blocks of ice were also collected and stored at -80 degrees C before being thawed for analysis. The sea-ice and brine was analysed for trace metals (Al, Zn, Cd and Co) for 5 different collection dates in 2004/2005.

|Data Collection:||Sea-ice blocks, brine, and underlying water samples were successfully collected throughout the austral winter of 2005. The sea-ice blocks were collected and stored at -80C, thawed during the summer and then filtered. They were analysed along with the brine samples in the UK.|
