Mendenhall and others (1916) assessed groundwater resources in California's San Joaquin Valley in 1910 to estimate the availability of groundwater of suitable quality for agricultural, industrial, and drinking water supplies. They inventoried nearly all existing wells, compiled depth-to-water at 4,002 wells, and collected water-quality data at 485 wells. Samples were collected from 114 wells for laboratory analysis of total dissolved solids (TDS), chloride, sulfate, bicarbonate, carbonate, calcium, magnesium, sodium+potassium, and silica (Mendenhall and others. 1916; Dole, 1909). Field assays were used to measure TDS, chloride, sulfate, bicarbonate, carbonate, and total hardness in samples from 371 wells (Mendenhall...

This set of 4 rasters shows mean temperature of the warmest month (deg C * 10) for Western North America under the B1 Emissions Scenario from the Intergovernmental Panel on Climate Change (IPCC). One layer shows the historic period (1961 to 1990), and there are three layers of future climate projections representing the 2020s, the 2050s, and the 2080s. These future layers are ensemble averages across all 23 CMIP3 AOGCMs (Coupled Model Intercomparison Project 3 Atmosphere-Ocean General Circulation Models). All layers have a resolution of 1 km, and are designed to capture climate gradients, temperature inversions, and rain shadows in the mountainous landscape of western North America. These data, originally published...

This metadata references the polygonal ARC/INFO GIS cover showing the current and historic distribution of potential habitat, or range, of the Greater Sage-grouse (Centrocercus urophasianus) and Gunnison Sage-grouse (Centrocercus minimus) in Western North America. This data was initially researched and compiled by Dr. Michael A. Schroeder, research biologist for the Washington State Department of Fish and Wildlife. The initial draft of current and historic range data was mapped and submitted to state, federal, or provincial natural resource agencies and other experts for review, comment, and editing. The final product represents the best available science and expert review available at the time of compilation.Definition...

Climate projection data were downloaded from the Climatewizard application for the coastal region for the Gulf of Mexico. Climate projection data represent the monthly, seasonal, and yearly mean for the time period of 2000-2050 for the following variables: AET:PET ratio, Moisture deficit, Moisture surplus, PET, Precipitation, Temperature, Rainfall Anomaly, and Standard Precipitation Index. In addition, models representing change in the average mean from period of (1961-1990) isavailable for each of the variables. Each projected variable is modeled using three different emission scenarios High (A1), Medium (A1B) and Low (B1).

This database for the Oregon, California, Mormon Pioneer, and Pony Express National Historic Trails is comprised of digital topographic data and reference line established using point data gathered with Global Positioning System (GPS) technology which represents only an approximation of the centerline of the trails system. This database, which is to be used in conjunction with ArcView software, is provided to assist the user in analyzing the visibility of any proposed location within 5 miles of the GPS reference line of the trails in order to evaluate effects to the landscape and setting of National Historic Trails in accordance with the National Historic Preservation Act and its implementing regulations at 36CFR...

This polygon feature class represents the final spatial extent and boundaries of the BLM Fire History Perimeter: Final Perimeters. The data is used for vegetation analysis such as habitat suitability, vegetation types and succession. Fire History can be used for current strategy and tactics on fires, fuels management, making forecasts for fire planning, analysis of vegetation and for stabilization and rehabilitation activities after fire. There are internal and external reporting requirements on burned acreage on a daily and annual basis. This will also provide timely updates for public web-services. These data are provided by Bureau of Land Management (BLM) “as is” and might contain errors or omissions. The User...

The Interior Department’s Climate Science Centers, managed by USGS, are helping the National Park Service pinpoint the specific impacts of climate change on parks and their cultural and natural resources. Doing so will help managers answer a critical question: which resources will require human intervention to ensure their continued existence?
