Hydrogen/deuterium isotope ratios are given for all samples, and for a subset, there are oxygen isotope ratios, and a deuterium-excess. Values are reported relative to VSMOW, +/- 1.0 per mil for hydrogen, and +/- 0.1 for oxygen. 1993-09-15 1995-04-01 ground condition As needed USGS site 9; coordinates taken from 1996-97 GPS measurements at center of weir Parent Stream: Andersen Creek Provenance : GPS96-97.DOC ID: andrsn_h1 162.906356800000 162.906356800000 -77.622772000000 -77.622772000000 78m 78m meter House Stream at H2Description: USGS site 10; coordinates taken from 1996-97 GPS measurements at center of weirID: house_h2Provenance File Name :GPS96-97.DOC 162.741317749023 162.741317749023 -77.642982482910 -77.642982482910 81m 81m meter Santa Fe Stream at B2 ID: santafe_b2 USGS site 12; formerly N Taylor & Hendy Stream 162.266662597656 162.266662597656 -77.723052978516 -77.723052978516 0m 0m meter USGS site 1; coordinates taken from 1996-97 GPS measurements at center of weir Parent Stream: Canada Stream Provenance : GPS96-97.DOC ID: canada_f1 163.054733300000 163.054733300000 -77.613655000000 -77.613655000000 50m 50m meter USGS site 4;coordinates taken from 1996-97GPS measurements at center of weirParent Stream: Aiken CreekProvenance : GPS96-97.DOCID: aiken_f5 163.271942100000 163.271942100000 -77.602516000000 -77.602516000000 20m 20m meter Lyons Creek at B4 ID: lyons_b4 USGS site 19 162.274993900000 162.274993900000 -77.727776000000 -77.727776000000 Andrews Creek at mouth ID: andrws_mouth 163.044448852539 163.044448852539 -77.620834350586 -77.620834350586 Bartlette Creek at mouth ID: bartlt_mouth 162.416671752930 162.416671752930 -77.720832824707 -77.720832824707 Red River art Blood Falls ID: red_bfalls 162.268051147461 162.268051147461 -77.723335266113 -77.723335266113 Bowles Creek at mouth ID: bowles_mouth 163.050003051758 163.050003051758 -77.622222900391 -77.622222900391 USGS site 6; coordinates taken from 1996-97 GPS measurements at center of weir Parent Stream: Crescent Stream Provenance : GPS96-97.DOC ID: crescent_f8 163.184463500000 163.184463500000 -77.619064000000 -77.619064000000 23m 23m meter USGS site 7; coordinates taken from 1996-97 GPS measurements at center of weir Parent Stream: Delta Stream Provenance : GPS96-97.DOC ID: delta_f10 163.108444200000 163.108444200000 -77.624619000000 -77.624619000000 23m 23m meter 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 USGS site 2; coordinates taken from 1996-97 GPS measurements at center of weir Parent Stream: Huey Creek Provenance : GPS96-97.DOC ID: huey_f2 163.127410900000 163.127410900000 -77.604897000000 -77.604897000000 19m 19m meter Harnish Creek at F7ID: harnish_f7USGS site 17 163.232772827148 163.232772827148 -77.608329772949 -77.608329772949 USGS site 16 Parent Stream: Lawson Creek id: lawson_b3 162.269910000000 162.269910000000 -77.721248000000 -77.721248000000 Lizotte Creek at mouth ID: lizotte_mouth 162.483337402344 162.483337402344 -77.704170227051 -77.704170227051 USGS site 3; coordinates taken from 1996-97 GPS measurements at center of weir Parent Stream: Lost Seal Stream Provenance : GPS96-97.DOC ID: lostseal_f3 163.244400000000 163.244400000000 -77.595268000000 -77.595268000000 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> Not Applicable Not Applicable Field and/or Lab Methods The samples were obtained in 3 field seasons: 1993-94, 1994-95, and 1996-97. Water samples were taken from stream channels or other proglacial sources. Many are grab samples, taken for characterizing the general signal of a particular stream. Some are samples taken as a suite of samples along a stream path, with times noted, and distance along the stream noted. The samples were analyzed by Bruce Vaughn at the Stable Isotope Lab at INSTAAR (Institute of Arctic and Alpine Research), University of Colorado. For the samples obtained during the 1993-94 year, a duplicate set was analyzed by Tyler Coplen at the US Geological Survey, in Reston, Virginia. For the analysis of hydrogen isotopes, the uranium reduction method was used at INSTAAR, and the platinum-catalyst equilibration method was used at the USGS. For oxygen isotopes, the standard CO2/H2O equilibration method was used at both labs. There was agreement between the analyses done at the two labs.  The samples were obtained in 3 field seasons: 1993-94, 1994-95, and 1996-97. Water samples were taken from stream channels or other proglacial sources.
