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.

Concerns over environmental disturbance in the McMurdo Dry Valleys are increasing with increasing foot traffic from tourists and scientist. The effect of pedestrian disturbance were monitored by comparing the species composition, depth distribution and soil properties between adjacent high-, low- and no- traffic sites. This study began in the austral summer 1995/1996.

Investigation of the effect of penguins (high C and N inputs) on soil biota and soil properties was part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project. The moisture content of soil samples collected for organism extraction and identification was determined. Samples were gathered on December 5, 1997 from Cape Crozier.
