Stream Algal Abundances

Summary

Abstract: 

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been undertaken to monitor the abundance and species distribution of algal mats in glacial meltwater streams of the region. This table contains data showing the percent of total biomass (abundance) represented by algal type (brown, red, orange or green), phylum, species and morphotype for multiple streams, dates, and replications.
