Environmental Science & Technology, 1988
Delineation and remediation of subsurface contamination have become a major focus of environmental science during the past five years. Conventional technologies available for subsurface investigations always will be required to confirm and monitor subsurface contamination; however, quicker and less expensive techniques are useful for preliminary site ...

A China dataset of soil properties for land surface modelling (version 2, CSDLv2)
Earth System Science Data. Accurate and high-resolution spatial soil information is crucial for efficient and sustainable land use, management, and conservation. Since the establishment of digital soil mapping (DSM) and the GlobalSoilMap working group, significant advances have ...

Soil genesis, soil classification and soil survey
Geoderma, 1970Abstract Mutual relationships exist between soil genesis, soil classification and soil survey. The first two subjects are dealt with separately. Some of the general lines in soil genetic investigation are traced. Next trends in soil classification are dealt with.

The aim of a soil survey is to predict soil conditions at unvisited sites. In traditional soil survey, the use of statistics is principally for post hoc evaluation of the quality of the choropleth map in terms of purity and within- and between-map unit variance of soil properties. Probability sampling designs have been proposed for this.

Soil Survey for Urban Development
Geoderma, 1973Abstract As an aid to urban planning, a detailed soil survey is underway in the new Mill Woods district, City of Edmonton. Five soil associations — Ellerslie, Mill Woods, Argyll, Hercules, and Beaumont — are being mapped in the area. These soils represent the Chernozemic, Solonetzic, and Gleysolic Orders in the Canadian System of Soil Classification.

Water and gas sampling of natural discharges are the most common types of survey over known geothermal areas. However, where discharge features are few and where the extent of the field is not known, soil and soil-gas surveys can prove helpful. These surveys can identify permeable regions in a field and possible upflow or boiling zones.

Each spring and fall a soil moisture survey is conducted to determine the amount of plant-available moisture in the top five feet of many of the major soils in Iowa. Several of the sites are located in the Wallace Foundation for Rural Research and Development (WFRRD) area.

AAPG Bulletin, 1939
Attention was called to the important role that visual oil and gas seeps and mineralization phenomena have played in the location of oil and gas fields throughout the world. A. Beeby Thompson was quoted in part from his End_Page 1874------------------------------ paper entitled "The Economic Value of Surface Petroleum Manifestations," which appeared in
