The geochemical response of sedimentary archives to rapid recent glacier retreat at the western Antarctic Peninsula (WAP): from source to sink

Off King George Island (western Antarctic Peninsula) major and trace elements were studied in porewaters and sedimentary archives. The results of provenance analyses conducted on marine sediments from Maxwell Bay suggest regional climate variability during the Late Holocene. Moreover, concurrent wit...
