δ37Cl of waters from the Akyatan lagoon, Turkey

Abstract


We report the first δ37Cl data for surface waters of the Akyatan lagoon, Turkey, from 12 stations sampled over the period 2005 to 2006. The recorded variation of δ37Cl values is fairly small, from -0.4 to +0.6 ‰ vs. SMOC, though the environmental conditions were highly variable seasonally. The salinity of the studied waters varied from 2.8 to 95 g/L and the δD vs. δ18O plot significantly departures from the World Meteoric Water Line (WMWL) with a slope of 5.43±0.19. Chlorine isotopes indicate a weak positive correlation between δ37Cl and δD of water and its salinity. This may be due to mixing between seawater and distinct sources of freshwater. The small spread of obtained δ37Cl results demands enhanced precision of analysis and careful sample preparation.
