| Abstract: |
| |
As a part of the McMurdo Dry Valleys LTER program, isotope
ratios have been determined from 295 ice/snow samples in Taylor Valley,
Antarctica. 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.

Description:

Data from this table was submitted to Denise Steigerwald (MCM LTER data manager) by Bruce
Vaughn on a floppy disk. The file was in ascii text, tab delimited format, and can be found in the
data manager's home directory on INSTAAR's Unix system. Once submitted, the data manager
used Microsoft Excel and Access to fine-tune the file and get it in more of a relational mode.
Changes made include the following:
* The 'YR/ID' field was renamed to 'sample#', and had the year portion removed. Information for sample year is represented in the date field.
* The 'Type' field was renamed to 'sample type', and written out as "snowpit" rather the abbreviation "P".
Once the above changes were made, the file was exported into comma delimited ascii format and MS-DOS
text format for presentation on the web page. The resulting files (snptistp.dat and snptistp.txt) contain a link to this page.

Description:
|
|
The samples were obtained in 3 field seasons: 1993-94,
1994-95, and 1996-97. 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.
