This shapefile depicts individual campsites areas surveyed at 37 sandbar sites along the Colorado River through Grand Canyon, from Lees Ferry to Diamond Creek, from 1999 to 2024. Campsite areas were measured through total station surveys, outlining the perimeter of areas available for camping use at each study site. Campsite area is defined as an area with smooth substrate, typically...

Climate-driven stressors, non-native insects, and emerging diseases increasingly impact forest health across the Great Lakes region. Forest management strategies are required to mitigate these impacts. We examined one strategy, tree planting for adaptation to climate and emerald ash borer (hereafter referred to as adaptation plantings), as an approach for establishing tree species...

This data release contains vector shapefiles of gridded, monthly water use estimates for the United States part of the Salish Sea basin in northwestern Washington for the year 2017. The water use estimates are provided by category of use for public supply, domestic self-supply, agriculture, and aquaculture each and are further distinguished by surface water or groundwater sources. Data...

Paleoceanographers use the distribution of planktic foraminifers in downcore sediment samples to estimate past oceanographic and paleoclimate conditions. In this data release, U.S. Geological Survey (USGS) scientists provide foraminiferal census data (species relative abundance and raw counts) from cores taken in Pigmy Basin (located in the Gulf of America) aboard the research vessel (R...

These data were compiled to provide necessary inputs to run the models in our paper, Operating Lake Powell Under Uncertainty: Strategies for Sustainable Sand Management in the Colorado River. Objective(s) of our study were to identify dam release strategies for improved management of sand resources in Grand Canyon. These data represent model inputs. Hydrology inputs were derived from U.S...

Stream-like habitats in abandoned mine areas of New River Gorge National Park and Preserve were surveyed for stream salamanders in fall 2024. Methods included visual encounter surveys of transects up to 25m within stream-like mine water discharges in the Nuttallburg, Fayette Station, Hawks Nest Connector, and New River Gorge Bridge areas of the park. All stream salamander species...

This data release contains 57 high-resolution chirp sub-bottom profiles collected in the southern Great Salt Lake, Utah, by the U.S. Geological Survey in June 2021 during field activity 2021-615-FA. The dataset was acquired to image subsurface sedimentary structures and stratigraphy in support of efforts to characterize past earthquake events along the Great Salt Lake Fault, contributing...

This model archive summary (MAS) document and model calibration dataset describes a surrogate model used to compute suspended sediment concentrations at USGS streamgage 11509500 for water years 2019-2024. The methods used follow USGS guidance as referenced in Office of Surface Water (OSW)/Office of Water Quality (OWQ) technical memoranda 2016.07 (https://water.usgs.gov/osw/pubs/memo...

This dataset contains chemistry results for water, sediment, and various tissue samples collected upstream and downstream of a PFAS source (treated industrial wastewater). Samples were analyzed by a USGS laboratory (National Water Quality Laboratory; Denver, CO) and SGS-AXYS (Sidney, BC, Canada). Concentration, surrogate recovery, and blank results are presented within.

These data were compiled to measure the stand structure, including age class distribution, of Joshua tree (Yucca brevifolia and Y. jaegeriana) as measured on 61 1000 m2 plots.The objective of our study was to provide the U.S. Fish and Wildlife Service with demographic data, particularly on recruitment, of the Joshua trees for their use in decisions that the Service makes for the...

The products presented here document conditions at the Swan Lake National Wildlife Refuge, Missouri from March to May, 2025. Imagery was collected to document conditions at areas in the north (“N_wetlands”) and east (“E_wetlands”) portions of the refuge prior to restoration to modify hydrology and habitat and improve future management capabilities. Imagery also captured a section of...

These data were collected as part of the Stormwater Action Monitoring (SAM) program's Puget Small Streams (PSS) status and trends program. The data presented here were collected from 29 sites during water year 2020 for water temperature, air temperature, and sensor depth. Sensor depth was used as a surrogate for water depth and represents the arbitrary depth of water above the sensor...
