الوصف: Data on radiocesium speciation measured seasonally in black silt surface sediments in the shallow terrace and in the deepest southern part of Lake Juodis (Lithuania) in 2004-2005 are presented. It is shown that seasonal variations of radiocesium exchangeable fractions in the sediments in the shallow terrace are mainly related to its redistribution due to the vital cycle of green algae covering bottom surfaces - processes of their growth and decomposition. A seasonal course of those fractions in surface sediments of the deepest bottom areas of the lake follows a distinct pattern and is annually recycling. It is maximum in winter and declines due to stagnant bottom water zone disruption in summer. It is shown that surface sediments in the deepest bottom areas of the lake are not a radiocesium source during the formation of the anaerobic zone in bottom water in winter, and act in that case as its acceptor. The radiocesium remobilization to the bottom water is seasonal and site-specific. It is suggested to be due to three main processes: its diffusion from deeper and more active sediments, its redistribution during decomposition of organics freshly accumulated in surface sediments and a radiocesium flux induced by the mechanism of the seasonal anaerobic zone formation in near-bottom water. 2007 Elsevier Ltd.
