Tracer Experiment Stream Chemistry

Title: Tracer Experiment Stream Chemistry
Abstract:
As part of the new Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic aqueous geochemical sampling program has been undertaken. A series of terrestrial water samples have been collected and analyzed for major ion chemistry by ion chromatography. The concentrations of ions cover a wide range of total dissolved solids (TDS) from relatively pristine glacier ice to hypersaline lake waters. Some of the challenges which are encountered while trying to collect and analyze samples covering a wide range of concentrations in such a hostile environment are discussed.
