This dataset represents the soil texture from SSURGO and STATSGO soil descriptions for soil map units in the state of western Oregon that lie within the North Pacific Landscape Conservation Cooperative. Soil texture is the mineral particle size distribution of soil particles within a soil horizon. This dataset also documents rock fragments and organic matter that may contribute to water infiltration, storage and relocation within the surface horizons of the soil profile. For reference, see NRCS soil texture triangle: http://soils.usda.gov/technical/aids/investigations/texture/

To determine habitat attributes and processes suitable for the growth of Coccidioides, soils were collected from sites in Arizona, California, and Utah where Coccidioides is known to have been present. Humans or animals or both have been infected by Coccidioides at all of the sites. Soil variables considered in the upper 20 cm of the soil profile included pH, electrical conductivity, salinity, selected anions, texture, mineralogy, vegetation types and density, and the overall geomorphologic and ecological settings. Thermometers were buried to determine the temperature range in the upper part of the soil where Coccidioides is often found. With the exception of temperature regimes and soil textures, it is striking...

All sediment samples from auger holes, outcrops, and cores are processed to determine texture. The 1-2 mm coarse sand fraction is packaged separately, and about half of these fractions are categorized lithologically by a glacial geologist. The data are recorded on paper data sheets and in a database.

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Subcropping geology for the Mid-Atlantic Coastal Plain was compiled and interpreted from available published sources. Formation contacts were interpolated across unmapped areas. Inconsistencies in nomenclature, interpretation, and scale were resolved to the extent possible, although some remain because of differences in mapping resolution among different areas. For more information, see U. S. Geological Survey Professional Paper...
The U.S. Geological Survey (USGS) has generated a new classification and map of the lithology of surficial materials for the contiguous United States. This was developed as part of an effort to map standardized, terrestrial ecosystem distributions for the nation using a classification developed by NatureServe (Comer and others, 2003). This ecosystem mapping methodology, which delineates ecosystems by mapping and integrating their major structural components, was first developed for South America (Sayre and others, 2008) and is now being implemented globally (Sayre and others, 2007). Surficial lithology strongly influences the differentiation and distribution of terrestrial ecosystems, and is one of the key input...
