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 ash-free dry mass represented by algal type (brown-colored, red-colored, orange-colored, or green-colored algae, filamentous, sand, rock or moss) and incubation type (light, dark, or none) for multiple streams, dates, and replications.
