Data

Geophysical data including multibeam bathymetry and backscatter, side scan sonar, and chirp subbottom were collected by Coastal Carolina University Center for Marine and Wetland Studies, Conway, South Carolina, in June 2016 in collaboration with the USGS St. Petersburg Coastal and Marine Science Center in the nearshore environment of Cape Canaveral, Florida. The goal of the effort was to broadly c

AVI files documenting raccoon (Procyon lotor) foraging for apple snails (Pomacea maculata) on a water hyacinth mat at Mandalay National Wildlife Refuge. Videos were taken with various models of Moultrie camera traps between January and March 2017.

The bathymetric data set was collected in Rock Run on Dec. 10, 2015 by USGS ILWSC staff Clayton Bosch and Louis Pappas. The bathymetric data were collected with an RD Instruments 1200 kHz ADCP (S/N 8617) and Trimble Ag 162 GPS mounted on the M/V La Moine. A temporary reference point (TRP) was established on the north side of the footbridge over the connecting channel to the Des Plaines River. The

The active layer data available here has been collected as part of a collaborative monitoring project between the US Geological Survey, Yukon River Inter-Tribal Watershed Council, and Yukon River Basin communities known as the Active Layer Network (ALN). The active layer is the layer of soil above the permanently frozen ground (permafrost) that thaws during the summer months and freezes again in t

The Southwest Exotic Plant Mapping Program (SWEMP) is a collaborative effort between the United States Geological Survey and federal, tribal, state, county and non-governmental organization (NGO) partners in the southwest. This project is an ongoing effort to compile and distribute regional data on the occurrence of non-native invasive plants in the southwestern United States. The database represe

Nutrients, such as nitrogen and phosphorus, are essential for plant and animal growth and nourishment, but the overabundance of bioavailable nitrogen and phosphorus in water can cause adverse health and ecological effects. It is generally accepted that major increases in the primary production of surface-water bodies due to high inputs of nutrients is now the most important polluting effect in sur

This dataset describes baseflow and stormflow concentration data for the constituents of nitrogen and phosphorus and suspended sediments for watersheds included in a paired watershed study including a forested reference watershed and two urban watersheds with centralized or decentralized stormwater management in Clarksburg, Maryland USA USA. Surface water samples were collected between the years 2

Time-series of sediment chemistry, including organic biomarker composition and bulk inorganic geochemical analytes, from samples collected over a one-year period in a sediment trap. The sediment traps were deployed at a depth between 603 m to 1318 m, and they were programmed to rotate a 250 mL sample bottle at 30 d intervals, delivering 12 samples during the 1-year deployment between August 2012 a

The Barrier Island and Estuarine Wetland Physical Change Assessment was created to calibrate and test probability models of barrier island estuarine shoreline and sandline change for study areas in Virginia, Maryland, and New Jersey. The models examined the influence of hydrologic and physical variables related to long-term and event-driven (Hurricane Sandy) estuarine back-barrier shoreline and ov

Data provided from the Virginia Department of Environmental Quality (DEQ) including simulated values of 72 hydrologic metrics, or indicators of hydrologic alteration (IHA), 37 fish metrics, and 64 benthic invertebrate metrics were reviewed to assess significant flow-ecology relations that may be developed. Hydrologic alteration was represented by simulation of streamflow record for a pre-water-wit

The U.S. Geological Survey in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District has produced this dataset of compaction values in the Chicot and Evangeline aquifers in the Houston‐Galveston region, Texas. This dataset shows compaction values of subsurface sediments (mostly in the fine-grained s

Potential pollinator habitat was derived by ranking land use classifications and grassland quality based on ground truthing and remotely sensed features indicative of remnant prairie. High resolution (10m) land use data served as the basemap (Hartley et al 2017) from which most categories were identified. All known prairie remnants, prairie plantings, and clusters of mima mounds were delineated. M
