| Abstract: |
| |
As part of the 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
from the stream waters. This dataset shows concentrations of lithium, sodium, potassium,
magnesium, calcium, iron, chlorine, bromine, silicon, fluorine, sulfate, and hydrogen ions
found in various streams of the McMurdo Dry Valleys.

| Geographic Coverage: |
|
Geographic Description: | Study areas are located in the McMurdo Dry Valleys of southern Victoria
Land, Antarctica (on the western coast of the Ross Sea at 77oS). Although the majority of the
streams in the study are found in Taylor Valley, data has also been collected from streams in
the nearby Miers, Alph, Wright, Pearse, Garwood, and Victoria Valleys. An extensive network of
gauging stations was set up throughout these valleys to monitor the stream hydrology. While
collecting hydrology data, stream water samples to be used for chemical analysis are also
gathered. Sample locations for stream chemistry data thus coincides with those for hydrology
samples. Locations also remain consistent from season to season. Specific latitudes and
longitudes for each stream gauge can be found in this site. |

Description:

The original iterations of the 'strmchem' file (stream chemistry data) were
created by Kathy Welch, and submitted to Denise Steigerwald (the data manager) at the
Institute of Arctic and Alpine Research (INSTAAR). These files are currently located on the
PC in the data manager's office at INSTAAR. Following discussions between Kathy Welch and
Denise Steigerwald, it was decided to remove some fields (eg., dilution factor), and add
others (eg. strmgageid, collection date, comments for each type of measurement) to these
files in order to make them more consistent and relational for future references. Following
these revisions, they were imported into Microsoft Access and saved in a table named "Stream
Chemistry / Ion Concentrations". This table was exported as an ascii, text, comma delimited
file (strmchem.dat) and as an MS-DOS text, table layout file (strmchem.txt), to present on
the MCM LTER web site. Both of these files are linked to this web page above.
