Geophysical Data Collected during the 2014 Minute 319 Pulse Flow
Geophysical methods were used to monitor infiltration during a pulse flow release of water in the Colorado River delta in Mar-May 2014. Electromagnetic-induction methods were used at 14 transects in the limitrophe reach of the River between the U.S. and Mexico, and further south in Mexico. These data are sensitive to variation in soil texture and water content. The repeat direct-current resistivit

Geospatial data set of bathymetric survey of lower Sixmile Creek Reservoir, Ithaca, New York, 2015
Water depths were measured during November 2015 and bathymetric elevations were computed for the lower Sixmile Creek reservoir in Ithaca, Tompkins County, N.Y. These data were used to create a bathymetric surface (TIN) of the reservoir. Data collected in 1938 were used to create a second TIN and a contour line shapefile. This dataset includes the ADCP-measured transect data and manually-measured p
High-resolution digital elevation dataset for Newberry Volcano and vicinity, Oregon, based on lidar survey of August-September, 2010 and bathymetric survey of June, 2001
Newberry Volcano, one of the largest Quaternary volcanoes in the conterminous United States, is a broad shield-shaped volcano measuring 60 km north-south by 30 km east-west with a maximum elevation of more than 2 km above sea level. It is the product of deposits from thousands of eruptions, including at least 25 in (approximately) the last 12,000 years (the Holocene Epoch). Newberry Volcano has er
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
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 fea
Summer Activity Sensor Data from Collars Deployed on Female Polar Bears in the Chukchi Sea 1989 to 1995 and Southern Beaufort Sea 1989 to 2014
These are data collected from two types of activity sensors housed within collars deployed on female polar bears in the Chukchi and southern Beaufort Seas during the months of July through October between 1989 and 2014. Mercury tip-switches were deployed 1989 to 2009 and accelerometers were deployed 2009-2014. Activity sensor readings were related to habitats used by polar bears as described in th
Bifenthrin causes trophic cascade and altered insect emergences in mesocosms: implications for small streams
Direct and indirect ecological effects of the widely used insecticide bifenthrin on stream ecosystems are largely unknown. To investigate such effects, a manipulative experiment was conducted in stream mesocosms that were colonized by aquatic insect communities and exposed to bifenthrin-contaminated sediment; implications for natural streams were interpreted through comparison of mesocosm results
Hydrologic data for the effects of forest cover on base flow of streams in the mountainous interior of Puerto Rico
The U.S Geological Survey, in cooperation with the Puerto Rico Department of Natural and Environmental Resources, completed a study to determine whether a relation exists between the extent of forest cover and the magnitude of base flow at two sets of paired drainage basins in the highlands of the municipalities of Adjuntas and Utuado within the mountainous interior of Puerto Rico. One set of pair
Spatial Data for Sedimentation Survey of Lago Caonillas, Utuado, Puerto Rico, SeptemberNovember 2012
This data release contains spatial data for sedimentation survey of Lago Caonillas, Utuado, Puerto Rico and includes reservoir bottom contours and water depth data. The Puerto Rico Electric Power Authority (PREPA) owns and operates the Lago Caonillas reservoir, and since 1996, the reservoir has become an essential part of the Puerto Rico Aqueduct and Sewer Authority (PRASA) North Coast Superaquedu
Time Series Electromagnetic Induction-Log Datasets Collected through the 2014 Water Year in South Florida
Time series electromagnetic-induction log (TSEMIL) datasets are collected from PVC cased or uncased monitoring wells to evaluate changes in water conductivity over time. TSEMIL datasets consist of a series of individual electromagnetic-induction logs collected at a frequency of months or years that have been compiled into a dataset by eliminating small uniform offsets in bulk conductivity between
Chemicals of emerging and legacy concern in tissues of white sturgeon (Acipenser transmontanus) in the Columbia River near Hanford, WA (2009)
This dataset contains concentrations of 28 organochlorine pesticides, 6 polybrominated diphenyl ether (PBDE) flame retardant congeners, 3 dichlorodiphenyltrichloroethane (DDT) compounds, and 15 polychlorinated biphenyl (PCB) congeners in brain, muscle, gonad, and liver tissues of white sturgeon (Acipenser transmontanus). All concentrations are reported on a wet-weight basis. Fish samples were coll
Map and model input and output data covering N 40.0 40.375 and W 105.25 105.625 in the northern Colorado Front Range for analysis of debris flow initiation resulting from the storm of September 9 13, 2013
Rainfall on 913 September 2013 triggered at least 1,138 debris flows in a 3430 km2 area of the Colorado Front Range. Most flows were triggered in response to two intense rainfall periods, one 12.5-hour-long period on 1112 September, and one 8-hour-long period on 12 September. Data in this project pertain to an area bounded by N 40.0 40.375 and W 105.25 105.625 which includes many of the areas wh
