Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Delineation and characterization of remotely sensed vegetation conditions in spring-dependent ecosystems, Harney County, Oregon
This data release includes data processing scripts, data products, and associated metadata for a novel remote-sensing based approach to assess resilience of spring-dependent ecosystems to inter-annual changes in water availability. This approach uses remotely-sensed Normalized Difference Vegetation Index (NDVI) to (1) delineate surface moisture zones (SMZs) in the vicinity of mapped springs in a s
Remote sensing derived maps of tamarisk (2009) and beetle impacts (2013) along 412 km of the Colorado River in the Grand Canyon, Arizona
These data were compiled for quantifying the area of tamarisks (Tamarix spp.) in May 2009 and to quantify the area of beetle-impacted tamarisk in May 2013 within the 2009 tamarisk classification from Glen Canyon Dam to Separation Canyon, a total distance of 412 km along the Colorado River using the 2009 and 2013 0.2 m high-resolution airborne imagery datasets. We classified tamarisk presence in 20
Archive of Digitized Analog Boomer Seismic Reflection Data Collected during USGS Cruise USFHC in Mississippi Sound and Bay St. Louis, September 1989
The U.S. Geological Survey (USGS) Coastal and Marine Geology Program has actively collected geophysical and sedimentological data in the northern Gulf of Mexico for several decades, including shallow subsurface data in the form of high-resolution seismic reflection profiles (HRSP). Prior to the mid-1990s most HRSP data were collected in analog format as paper rolls of continuous profiles up to 25
Data Files to Support SEAWAVE-QEX Model for Simulating Concentrations of Selected Pesticides in the Continental United States, 1992-2012
Reported atrazine, carbaryl, chlorpyrifos, and fipronil concentrations for selected U.S. Geological Survey pesticide sampling sites were downloaded from the U.S. Geological Survey National Water Information System (NWIS) and modified for input into the SEAWAVE-QEX model. Modifications included identification of appropriate censoring limits to use for samples in which the pesticides were not detect
Huron River near Hamburg, Michigan, flood-inundation model and field data
Digital flood-inundation maps for an 8-mile (mi) reach of the Huron River from downstream of Rickett Road to Strawberry Lake, Michigan, were created by the U.S. Geological Survey (USGS) in cooperation with Green Oak and Hamburg Townships, and the U.S. Army Corps of Engineers. The flood-inundation maps also include a 1.16-mi reach of the Ore Lake Tributary until it joins the Huron River, approximat
Early growth interactions between a mangrove and an herbaceous salt marsh species are not affected by elevated CO2 or drought, Louisiana saltmarsh, 2015
In recent decades the encroachment of woody mangrove species into herbaceous marshes has been documented along the U.S. northern Gulf of Mexico coast. These species shifts have been attributed primarily to rising sea levels and warming winter temperatures, but the role of elevated atmospheric carbon dioxide (CO2) and water availability may become more prominent drivers of species interactions unde
Landscape-scale wildlife species richness metrics
These raster data represent the results of a case study in Arizona on how vertebrate richness metrics can be used with existing state and federal guidance in wind and solar energy facility siting. Each of the four geodatabases (see Cross References) contain eight native terrestrial wildlife group models in Arizona: 1) all vertebrates, 2) amphibians, 3) reptiles, 4) birds, 5) mammals, 6) bats, 7) r
Water surface elevations recorded by submerged water level loggers in off-channel features of the middle and upper Willamette River, Oregon, Summer, 2016
Water surface elevations within seven Willamette River off-channel features (OCF; alcoves and side channels) were measured using submerged pressure transducers. Transducers were installed from late May through mid-October, 2016, when discharge of the Willamette River was between approximately 5,500 and 45,000 cubic feet per second at Salem, Oregon (USGS gage 14191000) and 3,500 to 17,500 cubic fee
Microsatellite Genetic Data for Sea Sandwort (Honckenya peploides) and Merckia (Wilhelmsia physodes), Alaska 2009-2016
This dataset contains sampling information and genetic data of 12 novel microsatellite loci developed and polymorphic in the Sea Sandwort (Honckenya peploides) and screened in Merckia (Wilhelmsia physodes) from Alaska. The allele sizes for the 12 microsatellite loci developed in this study are included for two populations of Sea Sandwort (Fossil Beach, Kodiak and Egg Bay, Atka) and one population
Predicted carnivore conservation hotspots in Peninsular Malaysia
A raster surface identifying hotspots of conservation priority based on 375 location records (89 unique geographic locations) of 28 species of Carnivora in Peninsular Malaysia. Hotspot analysis was conducted by calculating the Getis-Ord Gi* (pronounced G-i-star) statistic, using IUCN Red List status rank for each species as a weighting variable. Raster cell values represent a kernel density of z-s
Antibiotic-Resistant Escherichia coli in Migratory Birds Inhabiting Remote Alaska, 2015
This data set includes information on collections of fecal or cloacal samples from wild birds at two locations in Alaska, USA. Samples were screened or Escherichia coli (E. coli) and tested for resistance to multiple antibiotics using a variety of methods.
Data Release for Analysis of Vegetation Recovery Surrounding a Restored Wetland using the Normalized Difference Infrared Index (NDII) and Normalized Difference Vegetation Index (NDVI)
This dataset contains data used in the associated publication in the International Journal of Remote Sensing. The geodatabase contains four feature classes: AOI, MajorZone, MinorZone, and Green2007. Publication can be found at https://doi.org/10.1080/01431161.2018.1437297. Publication abstract: Watershed restoration efforts seek to rejuvenate vegetation, biological diversity, and land productivit
