[MIS34-P10] Paleolimnological changes of Lake Maruwanminami-ike and Maruwan-Oike in Soya Coast, East Antarctica during the Holocene
Keywords:Antarctic coastal lakes, Paleoenvironment, Paleolimnology, Diatom analysis, the Holocene
In this study, we estimate the Holocene environmental change of Soya Kaigan inferred from the analyses of a lake sediment core of Lake Maruwan-Oike (Mw4C-01) and Maruwanminami-ike (MwS4C-01) in Rundvagshetta ice-free area. We conducted Radiocarbon dating and Elemental Analyses by Matsumoto et al. (in prep) to carry out Total Carbon, Total Organic carbon, Total Nitrogen and Total Sulfur. In addition to these results, I clarify assemblage changes of fossil diatoms in the sediment core Mw4C-1 using a characteristic of diatoms living apart by water conditions such as salinity. From the results of diatom analyses and previous analyses, we will report about the Holocene hydrological and environmental changes in detail.
