Data

This U.S. Geological Survey (USGS) Data Release contains chemical analysis information on sediment core and oil samples collected at the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota, USA. Following a crude-oil spill in 1979, biodegradation of petroleum hydrocarbons in the contaminated aquifer has formed distinct zones of pH and/or redox...

Riparian systems across the southwestern United States are immensely important ecosystems and serve as biodiversity hotspots for a number of plant and animal species. However, recent challenges including non-native vegetation expansion, increased wildfire activity, and widespread vegetation die-offs, have substantially impacted the conditions of these ecosystems. This study was...

We developed maps of of projected present and future climate niches for 9 focal species (including 4 plants [common bearberry, Bebb's sedge, highland rush, and shrubby five-fingers], 2 birds [grasshopper sparrow and black-throated green warbler], and 3 salamanders [blue-spotted salamander, jefferson salamander, and marbled salamander]) to identify climate change refugia, areas on the...

This data release provides a vector geospatial polygon layer delineating 30 marine ecosystems, within the Large Marine Ecosystems (LME) surrounding Alaska, that can be identified by their similarities in oceanography and biology. These mesoscale ecoregions often cross LME boundaries. We examined the best information available for these mesoscale patterns in the distribution of biological

Adult sagebrush songbirds (primarily, Brewer's sparrow, sagebrush sparrow, and sage thrasher) were measured, color-banded, and tracked using multiple resight methods in Sublette County, Wyoming during 2020-2024. In addition, nests associated with each color-banded adult were identified. We conducted nest searching and monitoring efforts for any songbird species at study plots. Habitat...

This dataset includes information on total loggerhead sea turtle captures, recaptures, and their size ranges upon capture by year (2011–2024) in St. Joseph Bay, FL.

These are the data used for growth modeling in the paper ‘Growth of a threatened desert fish becomes resource dependent when released from temperature limitation in a regulated river’. Growth of ectotherms is strongly tied to temperature but can vary with other factors, especially food acquisition rates. River regulation is widespread globally and often significantly alters both...

Mauna Loa volcano, Island of Hawaiʻi, erupted from November 27 to December 10, 2022, sending lava flows across the summit caldera (Mokuʻāweoweo) and into the upper Southwest Rift Zone, before focusing in the Northeast Rift Zone at fissure 3, sending a lava flow down the north flank that threatened a major highway. During the eruption, there was a need for updated terrain data to update...

These hazard data accompany revisions to the 2023 50-state National Seismic Hazard Model (NSHM; Petersen and others, 2024; Petersen and others, 2022 for Hawaii; Powers and others, 2024 for Alaska) as documented in Powers and others (2026). In these revisions, we: adjust the representation of ground motion model (GMM) epistemic uncertainty where the central and eastern U.S. (CEUS) stable

Wetlands play an important role in carbon retention, which is greatly dependent on hydrological conditions. Therefore, the interest in wetland hydrology has increased over recent decades. In wetland hydrology, stable water isotopes (δ2H, δ18O) have found increasing use, as laser-based instruments have become readily available and allow for faster analysis and lower costs. However, the...

This data release contains recorded longitudinal survey and water-quality data taken on the Maurice and Cohansey Rivers from October 2021 through April 2024. Data were collected with a multi-parameter sonde and includes specific conductance, water temperature, latitude, longitude, and date and time of sample collection. Additional data were collected with the sonde data including...

These data are bathymetry (river bottom elevation) and depth-averaged velocities generated from the November 9–10, 2021, survey of the Barkley Dam tailwater from just downstream from Barkley Dam to approximately 600 feet upstream from the US 62 bridge (about 0.8 mile total length). Bathymetry and velocity data were collected using an acoustic Doppler current profiler (ADCP) with an...
