Samples were taken on:          * December 31, 1993     * January 3, 8, 10 and 13, 1994,     * December 12 and 22, 1994,     * January 6 and 9, 1995,     * November 27, 1995,     * December 5, 7 and 10, 1995, and     * January 12, 1998.    Name: Ross A. Virginia Role: associated researcher Name: Andy Parsons Role: field crew Name: Denise Steigerwald Role: data manager Name: Inigo San Gil Role: data manager completed McMurdo Dry Valleys LTER http://mcmlter.org/ unknown This file was created by Mark St. John at Colorado State University in Oct-1998, using raw data from the Excel workbooks '9312gswo.raw', '9412gswo.raw', '9511gswo.raw', and '9801gswo.raw'. The file format was suggested by the LTER data manager, to conform with the relational database structure. On 30-Oct-1998, the file was submitted to Denise Steigerwald, the MCM LTER data manager, located at INSTAAR, University of Colorado.                          Upon arrival at INSTAAR, the data manager combined the 4 data files, removed columns for latitude and longitude, and updated the location names to match those provided in the "soil measurement locations" file (from which latitude and longitude can be found). The resulting file was reformatted to present in ascii, comma delimited text and MS-DOS text (table layout) on the MCM LTER web site. Both of these files are linked to this web page above.                           On 28-Oct-1998, Andy Parsons discovered an error in the documentation of the storage temperature used for the soil samples collected. He informed the data manager of this error, resulting in an update from -8C to +5C in the methods portion of the page above.                           On 10-Nov-1998 Denise Steigerwald discovered a typo in the date shown for Cape Royds records represented in the 9312gswo file. Information colleced on 31-Dec-1993 showed a date of 31-Dec-1994. Denise revised these records in the Access database as well as the comma delimited text and MS-DOS text files on the web.  population dynamics theme LTER Core Areas English Located in middle of Beacon Valley.

Wharton, House and McKay streams flow into Lake Chad from the Suess Glacier. The overflow from Lake Chad then flows into the west end of Lake Hoare. There are many microbial mats in this area between the Hoare and Chad moats and around the spillway.

It is isolated under year-round ice cover, and is considerably more saline than seawater. Lake Vida is one of the largest lakes in the McMurdo Dry Valley region and is a closed-basin endorheic lake. The permanent surface ice on the lake is the thickest non-glacial ice on earth, reaching a depth of at least 21 metres or 69 ft. The ice at depth is saturated with brine that is seven times as saline as seawater. The high salinity allows the brine to remain liquid at an average yearly water temperature of 13 degrees Celsius or 9 farenheit. Hydrology: Lake Vida has at least three named inflows: Victoria River, Kite Stream, and Dune Creek. Victoria River passes through the Vida Basin into Victoria Valley, Victoria Land as ephemeral glacial meltwater from the Upper Victoria Glacier, draining from Victoria Upper Lake. Geology: In the vicinity of Lake Vida, a variety of geological features are noted, the most significant being glaciers, lakes, valleys, ridges, and summits. There are approximately 25 named glaciers within a 25 kilometres radius with the nearest being Upper Victoria Glacier, Packard Glacier, Clark Glacier, and Clio Glacier.
