A long-term soil manipulation experiment has been conducted as part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project. The response of soil organisms (nematodes, rotifers and tardigrades) to the treatments is monitored by sampling soil on an annual basis.

A study was conducted to examine soil microbial communities and associated geochemical parameters at potential glacial refugia and glaciated control sites throughout the McMurdo Dry Valleys region of Antarctica. Soil samples were collected as part of ongoing long-term monitoring efforts by the McMurdo Dry Valleys Long Term Ecological Research program (MCM LTER). The oldest samples used in this study were collected during the 1993-1994 austral summer, and the newest from the 2018-2019 austral summer.

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. The proportion of soil nematodes found in an anhydrobiotic survival state was monitored at various soil depths in Taylor Valley to help accomplish this. Samples were taken on 21-Nov-1994 and 26-Dec-1994.

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.

In the Antarctic Dry Valleys, soil polygons are prominent features of the landscape and may be key units for scaling local ecological information to the greater region. We examined polygon soils in each of the 3 basins of Taylor Valley, Antarctica. Our objectives were to characterize variability in soil biogeochemistry and biodiversity at local to regional scales, and to test the influence of soil properties upon invertebrate communities.

Investigation of the variation in soil biota and soil properties across the McMurdo Dry Valleys 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 determined. Chlorophyll-a samples were gathered on the following dates:
* December 12 and 22, 1994,
* January 9, 1995,
* November 8, 1995,
* December 7, 1995, and
* January 12, 1998.
