        <para>
          <literalLayout>As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys 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 chlorophyll, carbon, nitrogen, and hydrogen concentrations of algal communities and some mosses from the relict channel. The data constitutes the reactivated channel's algal and moss biomass data, along with measurements of the amount of carbon and nitrogen associated with algal mats for construction of nutrient budgets.</literalLayout>

        <para>
          <literalLayout>Data and metadata were migrated to the DEIMS system in 2015. Along, a new revision was entered to properly reflect date-ranges of the study and the egneral improvement of data related services. Data from this table was initially included in the raw data files specified under the variable for 'file name'. These are Microsoft Excel version 6.0 files and can be found in the McMurdo LTER data manager's home directory on INSTAAR's Unix system. Once submitted to INSTAAR, the data manager combined all of the stream biology files that included information for chlorophyll/biomass for the Relict Channel and removed any variables that had no direct influence. The resulting file is represented in the "relcbims.dat" file used on the web page.</literalLayout>

              <literalLayout>Within each transect, algal mats were visually identified as either orange, red, black, or green. Algal and moss samples were collected using a cork borer or a known area of substrate was scraped. Samples were stored in bottles until taken back to the lab for processing. Samples were filtered onto GF/C glass fiber filters. They were then extracted in buffered acetone and analyzed spectrophotometrically using the trichromatic method. Concentrations are reported in units of ug/cm2 for each pigment quantified (chlorophylls a, b, c, carotenoids, and phaeophyton). Carbon, hydrogen and nitrogen samples were air-dried (approximately 60 degrees C), then a weighed amount of algae was taken from the filter and analyzed on a Carlo Erba NA1500NCS element analyzer.</literalLayout>
