Oceanographic Observations Made Near South Padre Island, Texas, as Part of the South Padre Island Beach Replenishment Study, August 2018-February 2019
Beaches and water recreation are important to the South Padre Island, Texas area and across the United States. The movement of sediment in channels along beaches and the nearshore environment is important for coastal stakeholders and resource managers. Sediment removed by maintenance dredging is often placed back into the littoral system for potential beach replenishment. The movement of sediment
Tungsten Deposits in the United States (ver. 2.0, August 2020)
This is version 2.0 of Tungsten Deposits in the United States. This data release provides the descriptions of approximately 100 U.S. sites that include mineral regions, mineral occurrences (deposits), and mine features that contain enrichments of tungsten (W). This data release reports on U.S. mines and deposits with greater than or equal to 215 metric tons of tungsten metal (30,000 short ton unit
Data release for Linking land and sea through an ecological-economic model of coral reef recreation
Coastal zones are popular recreational areas that substantially contribute to social welfare. Managers can use information about specific environmental features that people appreciate, and how these might change under different management scenarios, to spatially target actions to areas of high current or potential value. We explored how snorkelers' experience would be affected by separate and comb
Topobathymetric elevation models of the upper Delaware River, USA - Version 1 - 10km tiles
This dataset includes topographic elevations (in meters) surrounding and bathymetric elevations within the upper Delaware River (USA). Bathymetric lidar data was acquired using the Experimental Advanced Airborne Research Lidar, version B. The EAARL-B is a successor instrument to the original EAARL bathymetric LiDAR sensor developed for mapping coral reef environments in clear water, but subsequent
Low-Temperature Thermochronometric Data from the Revelation Mountains, Western Alaska Range, 2013-2018
This data set provides low-temperature thermochronometric data from 16 rock samples collected from the Revelation Mountains area in western Alaska Range. These data are from three different analyses used to estimate cooling ages: 1) apatite (U-Th)/He, 2) zircon (U-Th)/He, and 3) apatite fission-track.
Data set for an ecological risk assessment of Firpronil compounds in US streams
The phenylpyrazole insecticide fipronil and its degradates are a potential surface-water contaminant and toxicant to nontarget species such as aquatic macroinvertebrates. To better understand how fipronil, fipronil sulfide, fipronil sulfone, desulfinyl fipronil, and fipronil amide affect aquatic communities, a 30-day mesocosm experiment was run. Rock trays were colonized with natural benthic commu
Short term soil carbon data and accretion rates from four marsh types in Mississippi River Delta collected in 2015
Short-term carbon accumulation rates were examined by collecting 10-cm deep soil cores at 24 sites located in marshes spanning the salinity gradient in coastal Louisiana. Percent moisture, bulk density, total carbon content, and the short-term accretion rates obtained with feldspar horizon markers were measured to determine total carbon accumulation and storage rates.
Soil Frost at Sleepers River Research Watershed, Danville, Vermont
Soil frost measurements have been made at Sleepers River Research Watershed starting in 1983. Measurements were made by U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory from 1983 to 1993, followed by the U.S. Geological Survey from 1993 to the present. Measurements started at 5 sites and has increased to 10 sites. Sites range in elevation from 225 to 670 meters and are
Fleas collected from black-tailed prairie dog burrows in 2016 and 2017
The data are a list of the number and species of fleas that were collected from black-tailed prairie dog burrows in Montana, North Dakota, South Dakota, Colorado, and New Mexico. Fleas were collected by swabbing ~100 burrows at 3 sites at each of 6 sites. Burrows were sampled twice each summer during 2016 and 2017.
Bayou Dupont Marsh and Ridge Creation (BA-48): 2016 land-water classification
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting
Multibeam Bathymetry Data Collected in 2018 offshore of Cedar Key, Florida
The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a multibeam bathymetry survey of a selected area offshore Cedar Key, Florida (FL) for the Florida Big Bend Pilot Study funded by USGS and the National Oceanic Atmospheric Administration (NOAA). The study involves federal, state, and local agencies who are taking a comprehensive approach to investi
Southeast Florida and Florida Keys: Antibiotic Resistance in Association with Ocean Outfalls and the Antibiotic Treatment of Diseased Corals
The purpose of these datasets was to define which samples contained antibiotic resistance genes (screened antibiotic resistance gene targets) and the number of detectable targets per sample (sediment, coral mucus and water). These data were determined from samples collected in Southeast Florida and the Florida Keys, in support of the Southeast Florida Coral Reef Initiative.
