The percent of anhydrobiotic (coiled) nematodes with relation to soil moisture, temperature, and salinity was determined. The study began at 1030 on 10 December 1997 and ended on 11 December 1997. The samples were taken at 0, 6, 12, 18, and 24 hrs. Samples were collected in the south side of Lake Hoare 1997-12-10 1997-12-11 ground condition In 2016, metadata was completed (Inigo San Gil)  This file was created by Pilar Tillberg on 10 May 2001, using raw data from the Excel workbook '9712swso.raw'.

Virginia Role: associated researcher Name: Inigo San Gil Role: data manager Not Applicable Not Applicable Field and/or Lab Methods  Soil was collected five times over a 24-hour period from six adjacent 1m2 plots on the south side of Lake Hoare, beginning at 1030 on 10 December 1997. Plots 1, 4, and 5 were amended with 5\3726 liters nanopure water applied to a 0.5m2 surface area of the soil at the beginning of the experiment.   Soil samples were taken for moisture content analysis as follows: Sampling bags were prepared with one sterile 'Whirlpak' bag and clean plastic scoop per sample. Very large rocks (&gt;20 mm diameter) were excluded from the sample. The soil was shoveled into the 'Whirlpak' bag until three quarters full (about 1.5 kg soil). The soil was mixed well in the bag, then the bag was closed tightly, expelling as much air as possible. The soil samples were stored in a cooler for transportation. On return to the laboratory (within 8 hours of sampling), the soils were stored at 4C until further processing.   In the laboratory, soil samples were handled in a laminar flow hood to prevent contamination. The Whirlpak bags of soil were mixed thoroughly prior to opening. A sub-sample of approximately 50g was removed and placed in a pre-weighed aluminum soil can, and weighed on a balance accurate to 0.01g. This sample was dried at 105C for 24 hours. The sample was removed, placed in a desiccator to cool down, and re-weighed. These data were used to calculate water content of the soil.    Soil was collected five times over a 24-hour period from six adjacent 1m2 plots on the south side of Lake Hoare, beginning at 1030 on 10 December 1997.
