Assessment of goods and valuation of ecosystem services (AGAVES) San Pedro River Basin, United States and Mexico Assessment of goods and valuation of ecosystem services (AGAVES) San Pedro River Basin, United States and Mexico
A consortium of federal, academic, and nongovernment organization (NGO) partners have established a collaborative research enterprise in the San Pedro River Basin to develop methods, standards, and tools to assess and value ecosystem goods and services. The central premise of ecosystem services research is that human condition is intrinsically linked to the environment. Human health and...

Characterization of geologic deposits in the vicinity of US Ecology, Amargosa Basin, southern Nevada Characterization of geologic deposits in the vicinity of US Ecology, Amargosa Basin, southern Nevada
Multiple approaches have been applied to better understand the characteristics of geologic units exposed at the surface and buried at depth in the vicinity of US Ecology (USE), a low-level commercial waste site in the northern Amargosa Desert, Nevada. Techniques include surficial geologic mapping and interpretation of the subsurface using borehole data. Dated deposits at depth were used...

U.S. Geological Survey Science for the Wyoming Landscape Conservation Initiative-2009 Annual Report U.S. Geological Survey Science for the Wyoming Landscape Conservation Initiative-2009 Annual Report
This is the second report produced by the U.S. Geological Survey (USGS) for the Wyoming Landscape Conservation Initiative (WLCI) to detail annual work activities. The first report described work activities for 2007 and 2008; this report covers work activities conducted in 2009. Important differences between the two reports are that (1) this report does not lump all the Effectiveness...

Chemical and textural controls on phosphorus mobility in drylands of southeastern Utah Chemical and textural controls on phosphorus mobility in drylands of southeastern Utah
We investigated several forms of phosphorus (P) in dryland soils to examine the chemical and textural controls on P stabilization on a diverse set of substrates. We examined three P fractions including labile, moderately labile, and occluded as determined by a modified Hedley fractionation technique. The P fractions were compared to texture measurements and total elemental concentrations

Social values for ecosystem services (SolVES): A GIS application for assessing, mapping, and quantifying the social values of ecosystem services-Documentation and user manual, version 1.0 Social values for ecosystem services (SolVES): A GIS application for assessing, mapping, and quantifying the social values of ecosystem services-Documentation and user manual, version 1.0
In response to the need for incorporating quantified and spatially explicit measures of social values into ecosystem services assessments, the Rocky Mountain Geographic Science Center, in collaboration with Colorado State University, has developed a geographic information system application, Social Values for Ecosystem Services (SolVES). SolVES can be used to assess, map, and quantify...

Three-dimensional geologic model of the Arbuckle-Simpson aquifer, south-central Oklahoma Three-dimensional geologic model of the Arbuckle-Simpson aquifer, south-central Oklahoma
The Arbuckle-Simpson aquifer of south-central Oklahoma encompasses more than 850 square kilometers and is the principal water resource for south-central Oklahoma. Rock units comprising the aquifer are characterized by limestone, dolomite, and sandstones assigned to two lower Paleozoic units: the Arbuckle and Simpson Groups. Also considered to be part of the aquifer is the underlying...

Temperature and precipitation history of the Arctic Temperature and precipitation history of the Arctic
As the planet cooled from peak warmth in the early Cenozoic, extensive Northern Hemisphere ice sheets developed by 2.6 Ma ago, leading to changes in the circulation of both the atmosphere and oceans. From ∼2.6 to ∼1.0 Ma ago, ice sheets came and went about every 41 ka, in pace with cycles in the tilt of Earth’s axis, but for the past 700 ka, glacial cycles have been longer, lasting ∼100...

Three-dimensional geologic modeling of the Santa Rosa Plain, California Three-dimensional geologic modeling of the Santa Rosa Plain, California
New three-dimensional (3D) lithologic and stratigraphic models of the Santa Rosa Plain (California, USA) delineate the thickness, extent, and distribution of subsurface geologic units and allow integration of diverse data sets to produce a lithologic, stratigraphic, and structural architecture for the region. This framework can be used to predict pathways of groundwater flow beneath the...

Flood hazard awareness and hydrologic modelling at Ambos Nogales, United States–Mexico border Flood hazard awareness and hydrologic modelling at Ambos Nogales, United States–Mexico border
Appropriate land‐use, watershed‐management, and flood‐attenuation plans are critical in the cross‐border urban environment known collectively as Ambos Nogales. This paper summarizes methodologies for predicting the watershed response associated with land‐use change within a spatial and temporal context through the use of a hydrological model in a cross‐border setting. The KINEROS2 model...

Ecosystem development in the Girdwood area, south-central Alaska, following late Wisconsin glaciation Ecosystem development in the Girdwood area, south-central Alaska, following late Wisconsin glaciation
Pollen analysis of two cores with discontinuous records from a peat bog near Girdwood, in south-central Alaska, provides the basis for reconstructing the first radiocarbon-dated outline of postglacial history of vegetation in the upper Turnagain Arm area of Cook Inlet. Pollen data from clayey silt underlying peat at one site indicate that the earliest known vegetation in the Girdwood...

Holocene stratigraphy and chronology of the Casper Dune Field, Casper, Wyoming, USA Holocene stratigraphy and chronology of the Casper Dune Field, Casper, Wyoming, USA
Activation chronologies of dune fields within the North American Great Plains are significant sources of paleoclimate information. Although many regional chronologies exist, several dune fields have been understudied, including the Casper Dune Field of central Wyoming. This study investigated aeolian dune sediment and buried soils of the Casper Dune Field. Complex parabolic and hairpin...
