Results of elemental analyses of desert tortoise (Gopherus agassizii) burrow spoil and undisturbed surficial soils in California, 2023

Bighorn sheep (Ovis canadensis) were frequently photographed by wildlife cameras when they visited desert tortoise (Gopherus agassizii) burrows in the eastern San Bernardino Mountains near Palm Springs, California, USA (Mesa Windfarm). A previous study suggested that sheep may have been utilizing the excavated spoil material from burrows as a mineral lick. We aimed to test this possibility by coll

Loggerhead Iridium Locations in Northwest Florida 2019-2021

This dataset is comprised of times, locations, and water temperatures collected from iridium satellite tags attached to 11 loggerhead sea turtles between 2019 and 2021.

Aquatic Stable Isotopes in the Owens River Gorge, CA 2017-2021

This dataset includes stable nitrogen-15 and carbon-13 isotope analysis data derived from freshwater aquatic and semi-aquatic primary producers, invertebrates, and fishes collected from five sampling sites (and one pilot site) within the Owens River Gorge, Mono and Inyo counties, CA, USA between 2017 and 2021. These sampling efforts were conducted in conjunction with the California Department of F

Santa Ana River Native Fish Population and Habitat Data, Santa Ana River, California, 2023

This dataset includes 2023 reach fish data and reach habitat data collected to support development of the upper Santa Ana River Habitat Conservation Plan for the Santa Ana Sucker (Catostomus santaanae) and the Arroyo Chub (Gila orcuttii) in the Santa Ana River, California.

Topographic and bathymetric data, imagery, and ground control data collected at Head of the Meadow Beach, Truro, Massachusetts in February and March 2024

The data in this release re-map the beach and nearshore environment at Head of the Meadow Beach in Truro, MA and provide updated environmental context for the 2020 CoastCam installation that looks out at the coast shared by beachgoers, shorebirds, seals, and sharks. This is a collaboration with the National Park Service at Cape Cod National Seashore to monitor the region that falls within the fiel

Map of Yellowstone’s Thermal Areas: Updated 2023-12-31

The U.S. Geological Survey, in cooperation with the National Park Service, Yellowstone Center for Resources, as part of work for the Yellowstone Volcano Observatory, has compiled a shapefile map of thermal areas and thermal water bodies in Yellowstone National Park. A thermal area is a continuous, or nearly continuous, geologic unit that contains one or more thermal features (e.g., hot springs, mu

Coal mine drainage effluents and associated solids major, trace, rare earth element and radium concentrations collected from Pennsylvania, USA

Discharges from abandoned coal mines and associated mine wastes represent historic and persistent sources of pollution in the Appalachian Basin, United States. In this study, we conducted the first-ever survey of radium (Ra) in coal mine drainage (CMD) water and solid samples in the United States. Samples were collected from 4 untreated coal mine discharges and 9 treated coal mine discharges (i.e.

Mariana common moorhen (Gallinula chloropus guami) blood and tissue sample collection data, 2000-2001

This data set describes blood and tissue samples collected from Mariana common moorhens from 2000-2001 in Guam and Saipan.

Nutrient and sediment concentrations, loads, yields, and rainfall characteristics collected at a USGS subsurface-tile edge-of-field agricultural monitoring site in South Central Michigan within the Maumee River Basin, 2019-2023

This data release contains nutrient and sediment concentrations, loads, and yields from a USGS subsurface-tile edge-of-field (EOF) agricultural monitoring site. Sampling and flow monitoring were performed at the outlet of a subsurface-tile that drains 14.7 acres of cultivated cropland. The site is located in South Central Michigan and discharges into a headwater stream of the Maumee watershed. Thr

Model Archive for an Impulse Response Emulator of Groundwater Contaminant Transport Models

This archive contains the code and other files to demonstrate the creation and application of an impulse-response emulator for process-based groundwater flow and transport models in MODFLOW/MT3D. This includes creating a synthetic modeling environment in MODFLOW/MT3D, using PEST++ to derive an impulse-response (A) matrix (as described in White et al., 2020), using this A matrix to create a groundw

Data and citations describing the connections between agriculture and water quality in the United States

This U.S. Geological Survey data release provides the data and citations for selected tables and figures in "Agriculture-A River runs through it-The connections between agriculture and water quality". This Circular is based on the National Water-Quality Assessment Project's study of Agricultural Chemicals: Sources, Behavior, and Transport. This study focused on the connections between agriculture

Inundation Exposure Assessment for Select Islands in the Republic of the Marshall Islands

As a low-lying island nation, the Republic of the Marshall Islands (RMI) is at the forefront of exposure to climate change impacts, including, primarily, inundation (coastal flooding). Increased water levels can stem from episodic events (storm surge, wave run-up, king tides) or from chronic conditions (long term sea-level rise). Land elevation is the primary geophysical variable that determines e
