Analysis of sediment cores collected in Ryder Bay and Marguerite Bay, Antarctica, 2005-2006


Box core samples were analysed for carbon and nitrogen isotopes, barium, aluminium and uranium and other lithogenic dust. Core dating was calculated and population analyses were used to determine species composition. The box cores were collected on the James Clark Ross (cruise numbers: JR112/113, JR136/137 and JR155) in January 2005 and December 2006. Swath bathymetry was also taken to identify optimum coring sites.
