Summary
Abstract:
Investigation of the effect of short-term variation in soil moisture and soil temperature on nematode anhydrobiosis as part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project. The percent of anhydrobiotic nematodes with relation to soil moisture and temperature was determined.
The study began at 0930 on 22 December 1997 and ended on 23 December 1997. The samples were taken at 0, 6, 12, 18, and 24 hrs.
Date Range:
December 22, 1997

Description:
Here are the details of the actual data columns, including labels, definitions, codes and scientific units used. The actual ancillary diurnal effects on soil biota data (and spreadsheet) is not large, and quite manageable.
