Lake Khubusgul, Mongolia, is one of the largest lakes of East Asia and located at a high elevation (1645m above sea level). This geographical characteristic makes Lake Khubusgul a unique place for paleoclimate studies using a continuous core sediment. A drilling core (HDP04) and gravity core (GC-4) were taken from the basin floor of Lake Khubusgul (50\u00b057\u002719\"N, 100\u00b021\u002732\"E; water depth, 250m) in 2004. The lengths of the HDP04 and GC-4 sediment cores were ca. 81m and 0.6m, respectively. AMS ^\u003c14\u003eC age dating for the latest Quaternary was performed for the 18 samples from the upper part of the HDP04 sediment cores (\u301c350cm depth) and the gravity core by an accelerator mass spectrometer (Model-4130 AMS, HVEE). AMS ^\u003c14\u003eC ages of total organic materials in the HDP04 sediment core do not become progressively older with depth, which suggest that sedimentary layers were disturbed by piston coring. The linear sedimentation rates are estimated to be 1.0 cm/kyr for 0-10 cm and 3.0 cm/kyr for 10-20 cm of the gravity core from Lake Khubusgul (GC-4), based on the conventional ^\u003c14\u003eC ages. Several radiocarbon age studies on other sediment cores from Lake Khubusgul show a rate of sediment accumulation ca. 1.3-5.7 cm/kyr [Fedotov et al., 2003; Nara et al., 2004]. The average linear sedimentation rates of GC-4 sediment core (0-20cm depth) are comparable with those from other cores from the Lake Khubusgul.", "subitem_description_type": "Abstract"}]},
