Stream Algal and Moss Biomass

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
production of algal mats in glacial meltwater streams of the region. This table contains data
showing the chlorophyll, carbon, nitrogen, and hydrogen concentrations of algal communities
and some mosses from selected streams from each of three Taylor Valley basins. The data set
constitutes the LTER algal and moss biomass data, along with measurements of the amount of
carbon and nitrogen associated with algal mats for construction of nutrient
budgets.
