Supplemental Data: Surface Infiltration and Unsaturated Zone Characterization in Support of Managed Aquifer Recharge in Bedell Flat, Washoe County, Nevada
This USGS data release presents tabular data and photos used to determine (1) the duration of flow, subsurface temperature, and concurrent infiltration along an ephemeral channel and (2) vertical change of soil moisture, texture, and pore-water chemistry in the unsaturated zone at selected locations. The data were collected to investigate the feasibility of managed aquifer recharge (MAR) for aquif
Trend Estimates of Common Raven Populations in the United States and Canada, 1966 - 2018
These data identify the mean population growth rate and ratio change in abundance of common raven (Corvus corax; ravens) populations from 1966 through 2018, delineated by ecoregions defined by the U.S. Environmental Protection Agency. This enables researchers and land managers to identify regions which may be more heavily affected by growing raven populations.
These data support the following p
Raven Occurrence and Density in the Great Basin Region of the Western United States (2007-2019)
We generated a spatially explicit map of categories of expected occurrence and density associated with predicted concentrations of resident and transient common ravens (Corvus corax; ravens) using the residuals from a generalized linear regression between the occurrence and density parameters.
These data support the following publication:

U.S. Register of Introduced and Invasive Species (US-RIIS), all versions
This is the landing page for all versions of the United States Register of Introduced and Invasive Species (US-RIIS).
The US-RIIS is comprised of three lists, one each for Alaska (AK), Hawaii (HI), and the conterminous United States (L48). Each list includes taxonomic and ecological information about introduced (non-native), established (reproducing) taxa that: are, or may become, invasive (harm
United States Register of Introduced and Invasive Species (US-RIIS)
Introduced (non-native) species that becomes established may eventually become invasive, so tracking introduced species provides a baseline for effective modeling of species trends and interactions, geospatially and temporally. The United States Register of Introduced and Invasive Species (US-RIIS) is comprised of three lists, one each for Alaska (AK, with 532 records), Hawaii (HI, with 6,075 re
Field data to support speciation with gene flow in a narrow endemic West Virginia cave salamander (Gyrinophilus subterraneus)
This data set is comprised of 4 files consisting of field observations, morphological measurements, and water quality measurements relevant to a publication on the classification and population status of the WV Spring salamander, Gyrinophilius subterraneus.
An updated range map for Plethodon shenandoah
The Shenanadoah Salamander (Plethodon shenandoah) is an endangered salamander found only in the mountains of Shenandoah National Park. Field surveys of the salamander were conducted from 2007-2022 using daytime cover object surveys. In order to capture the totality of P. shendandoah’s range we sampled from low to high elevation across a broad geographic range. We created a spatial generalized addi
Northwestern Pond Turtle Survey Data in Northern California Forest Streams (2021)
These data are from joint visual encounter and environmental DNA (eDNA) surveys conducted for northwestern pond turtles (Actinemys marmorata) in streams on privately-owned timberlands in northern California.
2015-2017 lidar-derived imagery of karst areas in Puerto Rico at 1-meter resolution
This raster dataset contains 1-meter lidar-derived imagery of 7.5 minute quadrangles in karst areas of Puerto Rico and was created using geographic information systems (GIS) software. Lidar-derived elevation data, acquired between 2015 and 2017, were used to create a 1-meter resolution working digital elevation model (DEM). To create this imagery, a hillshade was applied and a topographic position
2018 lidar-derived imagery of karst areas in Puerto Rico at 1-meter resolution
This raster dataset contains 1-meter lidar-derived imagery of 7.5 minute quadrangles in karst areas of Puerto Rico and was created using geographic information systems (GIS) software. Lidar-derived elevation data, acquired in 2018, were used to create a 1-meter resolution working digital elevation model (DEM). To create this imagery, a hillshade was applied and a topographic position index (TPI) r
Frequency domain electromagnetic induction (FDEM) geophysical data collected near the Agashashok River in the Noatak National Preserve, AK
Frequency domain electromagnetic induction (FDEM) data were collected in September 2016 near the Agashashok River and its tributaries, within the Noatak National Preserve near Kotzebue, AK to aid in local permafrost mapping. Data were collected with a GEM-2 instrument (1.6 m coil separation, Geophex, Ltd.); a broadband sensor that measures the bulk conductivity and magnetic susceptibility of the s
Assessment of fecal contamination sources to Alley Creek, Queens County, New York: Results from a sediment resuspension experiment, thermal imagery, and additional sample collection, 2020-2021
In cooperation with the New York City Department of Environmental Protection (NYC DEP), the U.S. Geological Survey (USGS) collected water and bed sediment samples along Alley Creek (Queens, New York) to help determine likely sources of fecal bacteria to the creek and Little Neck Bay. Potential terrestrial sources include stormwater, sewage via combined sewer overflow (CSO) and compromised infrastr
