Hydrochemical composition of glacial lakes on inshore Russian Antarctic stations

Abstract This paper reviews the chemical composition of 12 Antarctic lakes at offshore Russian stations in the period of seasonal work 55 and 58 RAE (Russian Antarctic Expedition) in December-January 2009-2010 and 2013-2014. Results of hydrochemical analyses of lake water, as well as their classification by ion composition, organic matter content, and mineralization, are presented in this paper. Low-level content of microelements in lake waters are also presented. Enrichment factors of lake waters in relation to ocean water were calculated and direct stratification of water from the surface to the bottom of Lake Progress was identified.
