Expeditionary studies in the western basin of the Aral Sea in September 2006

In September 2006, field studies were performed in the course of the seventh regular expedition of the Shirshov Institute of Oceanology of the Russian Academy of Sciences within the frameworks of the program for multidisciplinary studies and monitoring of the condition of the hydrophysical, hydrochemical, and hydrobiological systems of the Aral Sea under the anthropogenic crisis. This program has been implemented together with a series of scientific institutions of Uzbekistan and Kazakhstan starting in 2002. The results of the previous expeditions have been presented earlier in a series of publications (for example, [3–6, 12, 13]).
