Geochemical and Isotopic Tracing of Salt Loads into the Ramsar Listed Verlorenvlei Estuarine Lake, South Africa

δ2H and δ18O ratios, major ions, tritium and EC was used to constrain the sources of salt into the Verlorenvlei River and the Verlorenvlei Ramsar listed estuarine lake and wetlands. Each tributary contributes different quantities of salt into the Verlorenvlei River. The Krom Antonies River is charac...

Description
Summary:δ2H and δ18O ratios, major ions, tritium and EC was used to constrain the sources of salt into the Verlorenvlei River and the Verlorenvlei Ramsar listed estuarine lake and wetlands. Each tributary contributes different quantities of salt into the Verlorenvlei River. The Krom Antonies River is characterised by low EC, >300mS/m, in contrast to the Kruismans and Hol Rivers that have high EC,
