Research goals and objectives

The main fundamental project objective is to get high-performance record of climate and environment changes of Eastern Siberia in late Holocene based on lake and sea sedimentary sections. Within the bounds of climate reconstruction and natural environment pleistocene and Asia Holocene research problem, the solution of which “Baikal-drilling” project aimed at, it is planned to conduct a study and correlation of paleoclimatic sediment records of Baikal and with the Lena River records, its delta front and Arctic seas shelf, also their comparison with high-performance records from Siberia (dendrochronologic record of Taimyr (Vaganov and others, 1996) and other regions of northern hemisphere (Ice records of Greenland and Antarctica). It intended to get high-performance multi-component records from both regions with authorization of 50 and less years for late Holocene and for authorization of several years for time interval corresponding industrial revolution period (150 years).

Expected research results

With the help of interdisciplinary research data (sedimentological-geochemical, paleomagnetic, biological indicators), it is planned to develop precision-built methods of environment changes and climate determination with variations of substance composition of continental water bottom. There will be made an isotope oxygen curve based on diatomic Baikal algae leaves for paleoclimate reconstruction in Central Asia that will give out data with sea isotope curve.  

This work is based on the original method of diatomic algae leave allocation, it was developed in Geochemistry of SB RAS. In order to find out demolition peculiarities and weathering conditions of the petrogenic, rare elements and variations of isotope compositionc Sr, Pb, Nd in sediments, uncovered by Baikal and Khubsugul cracks. This will help to find out number of geochemical indicators of Central Asia environment and climate. It is planned to develop dataware and software of spectral-time analysis of cyclic (periodic) and directed (evolution) Central Asia natural environment and climate changes in the late Age of Mammals.
