Bathymetric and Tidal Discharge data for Wilderness Breach, Fire Island National Seashore, Long Island, NY, May 14, 2015

Nicole Ashley Casamassina, Jason Finkelstein, Jack Monti, Richard A. Cartwright, Riley R. Behrens, Scott Holewinski & Amy Simonson
In 2012, Hurricane Sandy created an open breach in the barrier island system along the south shore of Long Island, N.Y. This breach formed at a location known as Old Inlet and migrated rapidly westward over the winter storm season following Hurricane Sandy. In response, the National Park Service sought assistance from the USGS New York Water Science Center to help evaluate the hydrodynamics and geomorphology of the breach. The evaluation is centered on measurement...

Amphibian Occupancy and Effects of Habitat Use on Pesticide Exposure in Iowa Wetlands

Jennifer E. Swanson, Erin Muths, Clay L. Pierce, Mark W. Vandever & Kelly L. Smalling
Amphibians living in agricultural areas encounter many challenges. Two factors affecting individuals in these landscapes are habitat loss and pesticides. This thesis focuses on amphibians using agricultural wetlands in Iowa, where row crops such as corn and soybeans dominate the landscape. The goal of my first study was to determine the influences of site characteristics on amphibian presence and success. I used occupancy analysis to estimate proportion of area occupied by four species as a...

Ethanol and sodium acetate as a preservation method to delay degradation of environmental DNA: Data

Bridget Ladell, Liza Walleser, , Richard A Erickson & Jon J Amberg
This data contains environmental DNA (eDNA) sample assay results that were collected from water samples taken from a tank housing Asian carp and placed either on ice or at room temperature. At both treatment temperatures, water samples were left untreated or were treated with an ethanol and sodium acetate solution (EtOH-NaAc). This was done to evaluate an ethanol and sodium acetate solution to maintain the integrity of the DNA samples for the time between collection...

Determine the behavior and spatial distribution of bigheaded carp in response to seismic water guns: Data

Jose Rivera
This dataset includes exported hydroacoustic data (i.e., coordinates for acoustically detected fish targets, mean target strength of detected fish). The distance (m) from the water guns for each fish target was calculated using the gps coordinates of fish targets and the water guns location. The total lengths of fish targets were estimated from their target strength (dB), and fish were then classified as native fish or bigheaded carp according to their total length. This dataset...

Database of significant deposits of gold, silver, copper, lead, and zinc in Alaska

Keith R. Long & Meredith H. Burger
This data release provides descriptions and locations of 134 significant deposits in Alaska. Approximately 99 percent of past production and remaining identified resources of gold, silver, copper, lead, and zinc in the United States are accounted for by deposits that originally contained at least 2 metric tons (t) of gold, 85 t silver, 50,000 t copper, 30,000 t lead, and 50,000 t zinc. Deposits of this size comprise a very small fraction of the total...

Scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center, working in collaboration with the St. Johns River Water Management District, mapped surface water radon-222 (radon-in-water) and basic physical water column properties (for example, salinity and temperature) to examine submarine groundwater discharge at two locations, Eau Gallie North and Riverwalk Park, along the western shore of IRL. A previously published USGS data release ( contains the raw radon-222 data and physical...

Distribution and foraging patterns of common loons on Lake Michigan with implications for exposure to avian botulism: Data

Kevin P Kenow
Implantable satellite transmitters (e.g., Model PTT-100, Microwave Telemetry, Inc) were incorporated into the study to provide fine-resolution location data for a sample of the adult male common loons fitted with geolocator tags in 2010 and 2011. Transmitters were implanted in the abdominal cavity following procedures developed by Korschgen et al. (1996). The satellite transmitters were programmed to transmit on a variable schedule based on the anticipated stage of migration during the loon s annual cycle...

Data for sediment application to cypress and tupelo seedlings in greenhouse study - 2016

Isabel Grandy, Linda Messina, Evelyn R. Anemaet & Beth A. Middleton
The decline of Taxodium distichum, bald cypress, forests along the Gulf Coast of North America is partly due to elevation loss and subsequent flooding. In many coastal wetlands, a common approach for coastal restoration is to rebuild elevation through the application of dredge spoil, but this technique has not been used widely in coastal forests due to concerns of negatively impacting trees. This experiment explored health responses of Nyssa aquatica, water tupelo, and T. distichum...
