Algae Ash-Free Dry Mass 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 table contains data showing the ash-free dry mass represented by algal type (brown-colored, red-colored, orange-colored, or green-colored, filamentous, sand, rock or moss) and incubation type (light, dark, or none) for the Relict Channel in the Fryxell basin.
