Late Quaternary glacial-marine sedimentation in the Bransfield Strait off northeast Antarctic Peninsula
Systematical analyses of lithology, grain size, mineral composition, micro-biological thanatocoenoses and other geological proxies from the sediments of piston core Pc10, drilled in the central part of the Bransfield Strait, have been carried out. Based on the above data, together with the shipboard...
