Velocity, depth, and selected water quality profiles of the Lower Penobscot River Estuary in Maine, 2017
This data release includes transect data comprising velocity and depths collected by use of an acoustic-doppler current profiler (ADCP), and vertical profile data comprising conductivity, temperature, and depth by use of a conductivity, temperature, and depth (CTD) instrument, as well as tide elevation data at specified locations in the lower Penobscot River and Penobscot Bay (the Penobscot River

Airborne electromagnetic and magnetic survey data, Big Sioux aquifer, October 2015, Sioux Falls, South Dakota
Airborne electromagnetic (AEM) and magnetic survey data were collected during October 2015 along 769 line-kilometers over a 160-square-kilometer area that includes the Big Sioux aquifer between Sioux Falls and Dell Rapids, South Dakota, USA. Data were acquired with the CGG Resolve frequency-domain helicopter-borne electromagnetic system along with a cesium vapor magnetometer. Files included in thi
Electrofishing Results and Sampling of Bull Trout and Other Aquatic Vertebrates in the Vicinity of Yellow Pine, Idaho 2016
This data set summarizes electrofishing effort, observations, and tissue sampling of aquatic vertebrates near Yellow Pine, Idaho. Sampling was conducted using a backpack electrofishing unit at two reference sites including Cane Creek and Sugar Creek, and at three mine impact sites including Sugar Creek and Cinnabar Creek. Juvenile Bull Trout (Salvelinus confluentus) were present at all five sites
Evaluation of the Radar Stage Sensor Manufactured by Forest Technology Systems, IncorporatedResults of Laboratory and Field Testing
Two identical Radar Stage Sensors from Forest Technology Systems, were evaluated to determine if they are suitable for U.S. Geological Survey (USGS) hydrologic data collection. The sensors were evaluated in laboratory conditions to evaluate the distance accuracy of the sensor over the manufacturers specified operating temperatures and distance to water ranges. Laboratory results were compared to t
Pre- and post-event digital elevation models generated from high-resolution stereo satellite imagery of the 2016 Lamplugh rock avalanche in Glacier Bay National Park and Preserve, Alaska
The use of high-resolution remotely sensed imagery can be an effective way to obtain quantitative measurements of rock-avalanche volumes and geometries in remote glaciated areas, both of which are important for an improved understanding of rock-avalanche characteristics and processes. We utilized the availability of high-resolution (~0.5 m) WorldView satellite stereo imagery to derive digital elev
Shallow ATRIS (sATRIS) Images-Dry Tortugas National Park, Florida, 2011
Underwater digital images, single-beam bathymetry, and global positioning system (GPS) data were collected July 13 to July 17, 2011 within Dry Tortugas National Park, FL, USA. A total of 272,828 images of the seafloor and water column were collected along pre-defined transect lines and organized into 14 sets: track1, track2, track3, track4, track5, track6, track7, track8, track9, track10, track1
Sperm quality biomarkers complement reproductive and endocrine parameters in investigating environmental contaminants in common carp (Cyprinus carpio) from the Lake Mead National Recreation Area (1999-2006)
Lake Mead National Recreational Area (LMNRA) serves as critical habitat for several federally listed species and supplies water for municipal, domestic, and agricultural use in the Southwestern U.S. Contaminant sources and concentrations vary among sub-basins within LMNRA. To investigate whether environmental contaminant exposure is associated with alterations in male common carp (Cyprinus carpio)
Cottonwood Lake Study Area - Invertebrate Weights
This dataset contains aquatic macro-invertebrate sampling data (weights) for wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota. This dataset is part of the Missouri Coteau Wetland Ecosystem Observatory database that is a collection of abiotic and biotic data documenting biotic and abiotic responses to long-term climate and land-use change in the Prairie Pothole Region (PPR)

14.86 km Profiles of the Electric and Self-potential Fields Measured in the Lower Guadalupe River Channel, Texas Interior Gulf Coastal Plain, September 2016
This data release consists of three geophysical data sets measured in the lower Guadalupe River channel, south-central Texas, and one supplementary geophysical data set measured in a laboratory. The lower Guadalupe River is incised into the outcrop of the Carrizo-Wilcox aquifer in south-central Texas. The river and the aquifer are hydraulically connected across the outcrop, although the connectivi
