“…3). Lake Khubsugul (Hovsgol), which occupies a depression in the Baikal Rift zone of northern Mongolia, has been studied extensively (Altunbaev and Samarina, 1977;Golubev, 1992;Dorofeyuk and Tarasov, 1998;Fedotov et al, 2000Fedotov et al, , 2001Fedotov et al, , 2004Prokopenko et al, 2005). Organic carbon in Holocene deposits of diatomaceous silt decreases abruptly during the mid-Holocene at ca.…”

Holocene environmental change in Mongolia is reconstructed on the basis of recently published paleoclimate records, including lake levels, pollen assemblages, and eolian sediment records. These data indicate that the early Holocene of Mongolia is characterized by increasing temperature and humidity. Paleosol development, high lake-stands, and a more southward distribution of forest-steppe environments suggest the early-mid Holocene was humid. The mid-Holocene however is characterized by enhanced aridity, even though the onset and termination of the dry interval differs from place to place. Finally, humidity increased again during the late Holocene, as evaporation decreased in concert with dropping temperatures in Mongolia.

“…If the flux of sulfate from the atmosphere during the LGM was the same as at present and accumulated in the no-outlet lake, the flux per 1 cm 2 of paleo-Khubsugul, which had an area of 900 km 2 [Fedotov et al, 2004], was equal to 340 ug/cm7yr. Since the lake had no outlet, after its water evaporated to a sufficient extent in the wake of an arid interval, it became satu rated with calcium sulfate which accumulated in the sediments at the same rate.…”

The ancient Lake Khubsugul in North Mongolia is situated at the far reach of moisture from the North Atlantic into continental Asia [Kuznetsova, 1978]. It is remote from the Pacific Ocean and shielded from the China Sea and the Indian Ocean by high mountains. Information on the paleoclimates in this territory is scarce and sometimes controversial. In winter of 2003, due to a joint project (Khubsugul Drilling Project or KDP) of the Siberian Branch of the Russian Academy of Sciences and the Academy of Sciences of Mongolia, a 53‐m drilling core (KDP‐1) of sediments of Lake Khubsugul was obtained. This article describes the first results of paleomagnetic and geochemical studies of this core, which was found to span the time interval of the last 1.05 Myr. The data suggest that global climate oscillations manifested themselves in repeated desiccation and filling of the lake due to changes in humidity.

“…Importantly, several studies over the last decade have made use of diatoms as paleo-ecological and paleoclimate studies (Tarasov et al, 2000;Peck et al, 2002;Fedotov et al, 2000Fedotov et al, , 2004Rudaya et al 2008;Shinneman et al, 2009a, b,c), highlighting the need for a continued dialog on the taxonomy and ecological distributions of the group. Sampling for the current VOGL survey was designed to develop a diatom calibration model that could be used to interpret historical ecological change in sediment records (Shinneman et al, 2009a).…”

“…Diatom studies by Russian, Mongolian and international scientists have proceeded through the last century (e.g., Skvortzow, 1937;Morales & Edlund, 2003;Metzeltin et al, 2009); however, work has been largely focused on occurrence and distribution with little ecological or applied focus. In recent decades, interest has been building in Mongolia and surrounding regions to use diatoms in paleoclimatological (Tarasov et al, 2000;Peck et al, 2002;Fedotov et al, 2000Fedotov et al, , 2004Rudaya et al, 2008;Shinneman et al, 2009b, c), paleo-ecological (Shinneman et al, 2009a, b;Mackay et al, in press), and ecosystem health assessments (Soninkhishig et al, 1999, Soninkhishig andEdlund, 2001); making an understanding of the distribution and taxonomy of diatoms in Mongolia an important line of study for applied research.…”

The Valley of the Great Lakes (VOGL) in western Mongolia is dominated by two main (Uvs, Khyargas) and many minor closed basin lake systems. In 2004 and 2005, we sampled diatom communities from the surfi cial sediment of 64 lakes in the western Mongolian provinces of Uvs, Khovd, Zavkhan, and Bayan-Ulgii. Lakes ranged in water chemistry from fresh to hypersaline, oligotrophic to hypertrophic, and from low elevation VOGL lakes to high elevation lakes in the Altai Mountains. Over 300 diatom species were identifi ed in the sediment samples including a diverse fl ora limited to saline lakes, many widespread taxa, many new reports for the Mongolian diatom fl ora, and several new and possibly endemic species. We also review recent diatom literature from Mongolia including fl oristic surveys, paleo-ecology, and water quality studies.
