The University of Wisconsin Antarctic Soils Database contains data collected by Dr. James G. Bockheim and his colleagues from 1975 through 1987. Data include site information, air and soil temperature measurements, soil profile features, and surface boulder weathering features for 482 sites in the McMurdo Sound area of Antarctica. Soil profile descriptions are provided for soils inside the McMurdo Dry Valleys from 23 December 1975 to 22 December 1987, and outside the Dry Valleys from 13 November 1978 to 04 January 1986. Chemical and physical properties of soils at 214 sites are also provided. The study area is confined to 77 deg 7.5 min S to 78 deg S, 160 deg E to 164 deg E. Data are in tab-delimited ASCII text format, and are available via ftp.
