Algae Primary Productivity in Reactivated Channel

Summary

Abstract: 

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 data set includes results from light and dark incubations of algae to calculate net and gross primary productivity of algal communities from the Relict Channel in the Fryxell basin.
