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.  1995-11-18 1995-11-28 ground condition As needed Green Creek at F9Description: USGS site 8; coordinates taken from 1996-97 GPS measurements at center of weirID: green_f9 Provenance File Name :GPS96-97.DOC 163.059753417969 163.059753417969 -77.624099731445 -77.624099731445 25m 25m meter LTER Core Areas inorganic nutrients None <cntorg>McMurdo Dry Valleys LTER</cntorg> <onlink>http://mcmlter.org/</onlink> <span property="dc:title" content="McMurdo Dry Valleys LTER" class="rdf-meta element-hidden"></span> Name: Kathleen A.
