The interannual and interseasonal variations in the trace element composition of annual layers in bottom sediments of Lake Shira (Khakassia) are studied by means of X-ray scanning microanalysis with synchrotron radiation on the VEPP-3 (Novosibirsk) and BESSY-II (Berlin) storage rings. The relationship between sediment composition and weather and climatic conditions is established. The possibility of paleoclimatic reconstructions with annual temporal resolution is demonstrated.
