Observations of Sediment–laden Icebergs in Antarctic Waters: Implications to Glacial Erosion and Transport
Abstract Sediment-laden icebergs are rarely sighted in Antarctic waters. However, during the recent Deep Freeze 79-USCGC Glacier expedition to the George V Coast and the south-western Ross Sea, nine sediment-laden icebergs and several pieces of pack ice with surficial sediment layers were observed....
