 note = {P(論文), Sediment core samples are described from the area adjacent to Anvers Island north of the Antarctic Peninsula. The sequence is divided into three lithologic units, siliceous mud, alternation sandy silt and siliceous mud, and sandy silt with gravel, in descending order. These units suggest sedimentary environmental changes from under the ice sheet, to marine with highly influenced by fluctuation of the ice sheet, and finally to open marine. These major environmental changes are dated to ca. 16 ka BP and ca. 11.5 ka BP, respectively, based on uncorrected radiocarbon ages of organic carbon.},
