A.M. Dieye, David P. Roy, N.P. Hanan, S. Liu, M. Hansen, A. Toure
2012, Biogeosciences (9) 631-648
Spatially explicit land cover land use (LCLU) change information is needed to drive biogeochemical models that simulate soil organic carbon (SOC) dynamics. Such information is increasingly being mapped using remotely sensed satellite data with classification schemes and uncertainties constrained by the sensing system, classification algorithms and land cover schemes. In...

Joseph S. Duval
2012, Open-File Report 2004-1344
Quantitative mineral resource assessment, as developed by the U.S. Geological Survey (USGS), consists of three parts: (1) development of grade and tonnage mineral deposit models; (2) delineation of tracts permissive for each deposit type; and (3) probabilistic estimation of the numbers of undiscovered deposits for each deposit type. The estimate...
Chapter A6. Section 6.6. Alkalinity and acid neutralizing capacity
Stewart A. Rounds, Franceska D. Wilde
2012, Techniques of Water-Resources Investigations 09-A6.6
Alkalinity (determined on a filtered sample) and Acid Neutralizing Capacity (ANC) (determined on a whole-water sample) are measures of the ability of a water sample to neutralize strong acid. Alkalinity and ANC provide information on the suitability of water for uses such as irrigation, determining the efficiency of wastewater processes,...
Notes on interpretation of geophysical data over areas of mineralization in Afghanistan
Benjamin J. Drenth
2011, Open-File Report 2011-1258
Afghanistan has the potential to contain substantial metallic mineral resources. Although valuable mineral deposits have been identified, much of the country’s potential remains unknown. Geophysical surveys, particularly those conducted from airborne platforms, are a well-accepted and cost-effective method for obtaining information on the geological setting of a given area. This...

2011, Frontiers in Ecology and the Environment (9) 261-262
Since the days of MacArthur, three-dimensional (3-D) structural information on the environment has fundamentally transformed scientific understanding of ecological phenomena (MacArthur and MacArthur 1961). Early data on ecosystem structure were painstakingly laborious to collect. However, as reviewed and reported in recent volumes of Frontiers(eg Vierling et al. 2008; Asner et...

Joseph D. Zydlewski, Stephen M. Coghlan Jr., C. Gardner, R. Saunders
2011, River Research and Applications (29) 65-78
Dams are ubiquitous in coastal regions and have altered stream habitats and the distribution and abundance of stream fishes in those habitats by disrupting hydrology, temperature regime and habitat connectivity. Dam removal is a common restoration tool, but often the response of the fish assemblage is not monitored rigorously. Sedgeunkedunk...

Gladys Amaya, Laura M. Norman, George Frisvold
2011, Conference Paper, Proceedings of Santa Cruz River Researchers' Day
Assessing the sustainability of International policy or urban development requires consideration of the impacts of these decisions on Ecosystem Services, or the values that humans receive from the ecosystem, including market-land price, environmental, and human well-being values. Hedonic modeling helps to identify the market land price, considering the price is...
