North American Breeding Bird Survey Dataset 1966 - 2014, version 2014.0

The 1966-2014 North American Breeding Bird Survey dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings). These data are collected annually during the breeding season, primarily June and May, along thousands of randomly established roadside survey routes in the United States and Canada. Routes are about 24.5 miles (39.2 km) long with counting locations placed at regular intervals, for a total of 50 stops....

SEAWAT model used to evaluate the potential effects of alterations to the hydrologic system on the distribution of salinity in the Biscayne aquifer in Broward County, Florida.

Joseph D. Hughes, Dorothy F. Sifuentes & Jeremy T. White
A three-dimensional, variable-density solute-transport model (SEAWAT) was developed to examine causes of saltwater intrusion and predict the effects of future alterations to the hydrologic system on salinity distribution in eastern Broward County, Florida. The model was calibrated to conditions from 1970 to 2012, the period for which data are most complete and reliable, and was used to simulate historical conditions from 1950 to 2012. The model was used to (1) evaluate the sensitivity of the...

Sinkholes and Springs of the Ozark Physiographic Province, northern Arkansas, from Topographic Maps

Noel Turner
Springs and sinkholes in the Ozark Plateaus Physiographic Province (Ozarks) in Arkansas were digitized from 1:24,000 scale topographic maps to produce a digital dataset of karst features. Karst landscapes generally are created from bedrock dissolution that results in distinctive landforms, including sinkholes, springs, caves, and sinking streams, and a high degree of interaction between surface water and groundwater. The dataset can be used to better understand groundwater flow in the karst landscape of the Arkansas...

National Assessment of Hurricane-Induced Coastal Erosion Hazards: Gulf of Mexico Update

Kara S. Doran, , Justin J. Birchler, Nathaniel G. Plant & Jacquelyn R. Overbeck
These data sets contain information on the probabilities of hurricane-induced erosion (collision, inundation and overwash) for each 1-km section of the Gulf of Mexico coast for category 1-5 hurricanes. The analysis is based on a storm-impact scaling model that uses observations of beach morphology combined with sophisticated hydrodynamic models to predict how the coast will respond to the direct landfall of category 1-5 hurricanes. Hurricane-induced water levels, due to both surge and waves, are compared...

Hydraulic Mine Pits of California

James Orlando
This dataset is a compilation of boundary location polygons for 167 hydraulic mine pits located in northern California. This dataset was compiled from three sources, Topographically Occurring Mine Symbols (TOMS) database produced by the California Department of Conservation (2001), Yeend (1974), and on-screen digitizing, using current (2015) satellite imagery, of additional hydraulic mine pits not contained in either of these sources.

Landsat 8 Biome Cloud Validation Masks

The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center in Sioux Falls, SD developed a cloud validation dataset from 96 unique Landsat 8 images called the L8 Biome dataset. These images were selected from various locations around the world, and are evenly divided between eight unique biomes and three different cloud cover categories. The images are curated by biome and cloud cover to reduce bias in any one region or cloud cover...

Data used to estimate and project the effects of climate and land use change on wetland densities in the Prairie Pothole Region

Helen R Sofaer
These data were used to estimate models relating climate and land cover to wetland densities and develop projections under climate and land use change. Data for model estimation were derived from historical climate data, estimates of hydrological processes based on the Variable Infiltration Capacity model, National Wetlands Inventory, and the National Land Cover Database. Wetland densities were based on observations from the Waterfowl Breeding Population and Habitat Survey. Projected climate conditions were derived from ten...

Using an inter-lab study to revise methods for conduction 10- to 42-d water or sediment toxicity tests with Hyalella azteca

William G Brumbaugh Chris G Ingersoll
Studies have been conducted to refine USEPA, ASTM, and Environment Canada standard methods for conducting 42-d reproduction tests with H. azteca in water or in sediment. Modifications to the H. azteca method include better defined ionic composition requirements for exposure water (i.e., >15 mg/L of chloride and >0.02 mg/L of bromide) and improved survival, growth and reproduction with alternate diets provided as increased rations over time in water-only or whole-sediment toxicity tests. A total of...

Previous mineral resource assessment data compilation for the U.S. Geological Survey Sagebrush Mineral Resource Assessment Project

Heather L. Parks, Michael L. Zientek, M. Christopher Jenkins, Cassandra K Hennings, John C. Wallis, Duc M Nguyen & Pamela M. Cossette
This data release consists of a compilation of previously published mineral potential maps that were used for the Sagebrush Mineral Resource Assessment (SaMiRA) project. This information was used as guides for assessing mineral potential assessment of approximately 10 million acres in Idaho, Montana, Nevada, Utah, and Wyoming. Specifically, the compilation was used to identify the deposit types to be assessed and the deposit models to develop. The data release consists of georeferenced images of mineral...

Trace elements concentrations in pore water and surface water near the sediment-water interface in the Upper Columbia River, Washington (2015)

Stephen E. Cox, William G. Brumbaugh, Laurie S. Balistrieri, Ruth E. Wolfe, Monique Adams & Theresa D. Olson
Smelter slag containing copper and other trace elements is widespread in riverbed sediment of the upper Columbia River (UCR) of the United States. To evaluate potential risk to aquatic life concentrations of copper and other trace elements were measured in shallow pore-water and in river water samples collected near the sediment-water interface. Samples were collected using an in-situ pore-water profiler to collect a suite of four water samples from above, at, and below the sediment-water...

Sediment-quality and water-toxicity data from 10 sites on the Westside Creeks and San Antonio River, San Antonio, Texas, 2014

Sediment samples and samples for water-toxicity testing were collected during 2014 from several streams in San Antonio, Texas known locally as the Westside creeks (Alazn, Apache, Martnez, and San Pedro Creeks) and from the San Antonio River. Samples were collected once during base-flow and again after periods of storm-water runoff (post-storm conditions) to determine baseline sediment- and water-quality conditions. Streambed-sediment samples were analyzed for selected constituents, including trace elements and organic contaminants such as pesticides,...

GIS data for predicting the occurrence of cave-inhabiting fauna based on features of the Earth surface environment in the Appalachian Landscape Conservation Cooperative (LCC) Region

Mary C. Christman, Daniel H. Doctor, Matthew L. Niemiller, David J. Weary, John A. Young, Kirk S. Zigler & David C. Culver
Cave-limited species display patchy and restricted distributions, but are challenging to study in situ because of the difficulty of sampling. It is often unclear whether the observed distribution is a sampling artifact or a true restriction in range. Further, the drivers of the distribution could be local environmental conditions, such as cave humidity, or they could be associated with surface features that are surrogates for cave conditions. If surface features can be used to predict...

Data on annual total nitrogen loads and watershed characteristics used to develop a method to estimate the total nitrogen loads in small streams

Silvia Terziotti, Paul D. Capel & Scott C. Kronholm
This USGS Data Release represents the data used to develop multiple linear regression models for estimating the loads of total nitrogen in small streams. Recursive partitioning and random forest regression were used to assess 85 geospatial, environmental, and watershed variables across 636 small (less than 585 square kilometers) watersheds to determine which variables are fundamentally important to the estimation of annual loads of total nitrogen. These data support the following publication: Kronholm, S.C., Capel, P.D.,...
