          <literalLayout>As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys&#160;of Antarctica, water was diverted to a relict stream channel in order to reactivate the streamflow. The purpose of this experiment was to quantify the time scales of response to the arrival of water after many years of dessication. This table contains data showing the measurement locations&#160;(latitude, longitude and elevation) for the Relict Channel in the Fryxell basin.&#160;</literalLayout>

        <para>
          <literalLayout>&#160;Records generated from monitoring the Relict Channel had been submitted to&#160;Denise Steigerwald (the MCM LTER data manager) in the same files as core LTER data sets.&#160; &#160; &#160; &#160;Denise therefore went through these files, separated out any records dealing with the Relict&#160;Channel, and created new files with a similar layout as the core datasets. Coordinates&#160; (latitude, longitude and elevation) were then tracked down for each of the records, and&#160;synonymous location names were updated. The resulting 'relict_locs.dat' and 'relict_locs.txt'&#160;files were posted on the web in July, 2000. Fields for dataset code and location code were&#160;included in order to simplify generating links between different data and metadata fields,&#160;and assist in making the data more relational / useful in Oracle and ArcInfo.</literalLayout>

              <literalLayout>&#160;In October 1998, the MCM LTER data manager asked the team making stream&#160;measurements to track down coordinates for the Relict Channel measurement sites. Mike Gooseff&#160; provided the resulting information. It is unknown what was initially used to measure these&#160; latitudes, longitudes and elevations.</literalLayout>
