Soil Depth Effects on Chlorophyll-a Concentrations

Summary

Abstract: 

Investigation of the effect of soil depth on soil biota and properties was part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project. Chlorophyll-a concentrations from soil samples collected for organism extraction and identification was monitored at various soil depths in Taylor Valley in order to accomplish this. Samples were taken on 21-Nov-1994 and 26-Dec-1994.

Date Range: 

November 21, 1994 to December 26, 1994
