U.S. Geological Survey - Gap Analysis Project Species Habitat Maps CONUS_2001

Alexa McKerrow
Gap Analysis Project (GAP) habitat maps are predictions of the spatial distribution of suitable environmental and land cover conditions within the United States for individual species. Mapped areas represent places where the environment is suitable for the species to occur (i.e. suitable to support one or more life history requirements for breeding, resting, or foraging), while areas not included in the map are those predicted to be unsuitable for the species. While the actual distributions...

Avian Habitat Data; Seward Peninsula, Alaska, 2012

Lance B. McNew & Colleen M. Handel
This data product contains avian habitat data collected on the Seward Peninsula, Alaska, USA, during 21 May ? 10 June 2012. We conducted replicated 10-min surveys at 111 points located along 9 transects occurring over gradients of physical and biotic habitat conditions and recorded observations of individual birds identified to species. Survey points, or sites, were located approximately 500 m apart and observations of birds were limited to a maximum distance of 250 m to...

High-resolution geophysical data collected along the Delmarva Peninsula 2014, USGS Field Activity 2014-002-FA

E. Pendleton
The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy. A USGS cruise was conducted in the summer of 2014 to map the inner-continental shelf of the Delmarva Peninsula using geophysical and sampling techniques to define the geologic framework that governs coastal system evolution at storm-event and longer timescales. Geophysical data collected during the 2014 cruise include swath bathymetric, sidescan sonar, chirp and boomer seismic reflection...

Historic groundwater quality of in situ recovery (ISR) uranium mines, Texas

Susan M Hall
In situ recovery (ISR) uranium mining is a technique in which uranium is extracted by a series of injection and recovery wells developed in a permeable sandstone host rock. Chemical constituents (lixiviants) are added to groundwater injection wells to mobilize uranium into groundwater. Before mining, baseline water quality is measured by sampling groundwater from the aquifer intended to be mined and over and underlying units over a geographic area that reflects the proposed mine location....

Carbon Exchange Data - Pine Upland Sampling Location (Greater Everglades)

Barclay Shoemaker
Carbon dioxide exchange with the atmosphere over forested subtropical wetlands, such as cypress strands and pine forests in the Greater Everglades, is largely unknown. Here we report a first step in characterizing this atmospheric-ecosystem carbon (C) exchange, as measured with eddy covariance methods at three locations (Cypress Swamp, Dwarf Cypress and Pine Upland) for one year. This file is an Excel file containing data for the Pine Upland sampling location. It includes the following data...

Near-Surface Water-Quality Surveys of the Caloosahatchee River and Downstream Estuaries, Florida, USA

Travis M. Knight By Amanda C. Booth
Moving-boat surveys are used to produce water-quality maps at least six times per year. The boat surveys typically began at the boat ramp near Punta Rassa, enters San Carlos Bay, travel around Pine Island and finally travel upstream along the Caloosahatchee River, ending at the W. P. Franklin Lock and Dam (S-79). Sensor and coordinate data are recorded as the boat travels throughout the study area making measurements using a flow-through onboard pump system. Salinity,...

Mapping Extent and Change in Surface Mines Within the United States for 2001 and 2006

William Acevedo Christopher E. Soulard
Researchers with the USGS Western Geographic Science Center and Eros Data Center have developed a semi-automated procedure to map the country's mining footprint and establish a baseline to monitor changes in mine extent over time. The process includes a tool that uses seed points sourced from the US Energy Information Administration (EIA), USGS Mineral Resources Data System (MRDS), and USGS National Land Cover Dataset (NLCD) and recodes patches of barren land that meet a 'distance...

Health-Based Screening Levels for evaluating water-quality data

Health-Based Screening Levels (HBSLs) are non-enforceable water-quality benchmarks that can be used to (1) supplement U.S. Environmental Protection Agency (USEPA) Maximum Contaminant Levels (MCLs) and Human Health Benchmarks for Pesticides (HHBPs), (2) determine whether contaminants found in surface-water or groundwater sources of drinking water may indicate a potential human-health concern, and (3) help prioritize monitoring efforts. HBSLs were developed by the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program for contaminants that do not...

Carbon Exchange Data - Dwarf Cypress Sampling Location (Greater Everglades)

Barclay Shoemaker
This file is an Excel file containing data for the Dwarf Cypress sampling location. It includes the following data sheets: -working_stage - raw data from pressure transducer. Water distances above and below land-surface are computed in this worksheet. -raw_weather - raw data for wind direction, wind gust, incoming solar radiation, soil heat flux, net radiation, air temperature, relative humidity, temperature of air, water and soil, and volumetric water content. -work_weather - mean 30-minute mean calculation...

Estimates of soil water deficit during California drought, January 1, 2014

** September 16, 2014: Because this information has immediate and time-sensitive relevance to public health and welfare owing to the Governor of California's declared drought emergency, it is being released as preliminary information. As preliminary information, it had been reviewed and approved to meet the needs for timely best science, but the methodology is subject to refinement. The information is provided on the condition that neither the U.S. Geological Survey nor the U.S. Government may...
