dc.description.abstract | Holocene paleoenvironmental history in the western South Orkney Islands was reconstructedthrough the paleoecological analysis on the diatom taxa from sediment core GC02-SOI03. Thre diatom zones are identified on the basis of frequency of the critical taxa throughout the section: diatom assemblage zone I (533 cm∼360 cm), diatom assemblage zone II (352 cm∼240 cm), and diatom assemblage zone III (232 cm∼0 cm). High concentration of open water species and Eucampia antarctica var. antarctica in the diatom assemblage zone I indicates open water environment with little sea-ice during the early Holocene. Sea-ice species and Eucampia antarctica var. recta increase in abundance in the diatom assemblage zone II, suggesting increased sea-ice cover in the study area since 5 ka. Even more extensive sea-ice coverage during the late Holocene is implied by abundant sea-ice species and decreased Corethron criophilum in the diatom assemblage zone III. | - |
