Sedimentary charcoal particle data and 14C age control measurements derived from a core recovered from Paixban, a wetland/lake in northern Guatemala in 2003
Sublacustrine landslide and tsunami models from Lake Quinault, Washington Sublacustrine landslide and tsunami models from Lake Quinault, Washington
This USGS data release provides model setup files to simulate a hypothetical sublacustrine landslide in Lake Quinault and resulting tsunami waves.
Submerged Grain Size Maps in the Santiam River Basin, Oregon Submerged Grain Size Maps in the Santiam River Basin, Oregon
The size and distribution of riverbed grain size plays a foundational role in river morphology and ecology. This study (White and others, 2025) quantifies submerged riverbed grain size at high resolution (1 square meter) across 260 kilometers of geomorphically diverse river corridors in the Santiam River Basin, Oregon, by pairing bathymetric lidar point-clouds collected in 2023 with...
Substrate Imagery Classifications for Lake Trout Spawning Habitat in Lake Ontario, 2023-2024 Substrate Imagery Classifications for Lake Trout Spawning Habitat in Lake Ontario, 2023-2024
This dataset is the result of international collaborative efforts by the United States Geological Survey, the United States Fish and Wildlife Service, the New York State Department of Environmental Conservation, the Ontario Ministry of Natural Resources and Forestry, and the Canadian Department of Fisheries and Oceans. These data provide substrate information along the shoreline of Lake...
Subsurface Stratigraphic Horizon Data Collected from Oil and Gas Wells in the Sacramento-San Joaquin Valley and Surrounding Region Subsurface Stratigraphic Horizon Data Collected from Oil and Gas Wells in the Sacramento-San Joaquin Valley and Surrounding Region
This report and associated dataset, contains subsurface geologic information collected in the Sacramento-San Joaquin Valley. The primary data includes X, Y, Z locations of stratigraphic horizons and, to a much lesser extent, geologic structures where penetrated by oil and gas wells in the subsurface as recorded in well logs and well records. Selected oil and gas wells are not only...
Subtidal Ecosystems at San Nicolas Island, California (ver. 1.1, December 2025) Subtidal Ecosystems at San Nicolas Island, California (ver. 1.1, December 2025)
The monitoring program at San Nicolas Island (SNI) was conceived in anticipation of the potential reintroduction of southern sea otters to the island. Subtidal monitoring was initiated in autumn of 1980 at six sampling sites positioned around the island to sample communities exposed to a range of wave exposures and other oceanographic conditions. Three additional sites were subsequently...
Sulfur isotopes and geochemistry of sulfate and sulfide minerals in the Mountain Pass Intrusive Suite, 2025 Sulfur isotopes and geochemistry of sulfate and sulfide minerals in the Mountain Pass Intrusive Suite, 2025
Sulfur minerals, including sulfates (barite, celestine) and sulfides (pyrite, galena, chalcopyrite) are common throughout the Mountain Pass carbonatite. Changes in the sulfur isotope chemistry of sulfate and sulfide minerals record changes in temperature and oxygen fugacity in the system from which they precipitate, and early primary sulfate and/or sulfide minerals may record the primary...
Summarized model outputs for a predator-prey-competitor model for Macrhybopsis and Scaphirhynchus in the Lower Missouri River Summarized model outputs for a predator-prey-competitor model for Macrhybopsis and Scaphirhynchus in the Lower Missouri River
Data represents summarized model outputs for various simulation scenarios performed used the Fish community bioenergetics model published at: https://doi.org/10.5066/P1XAZ6K9. A number of scenarios were explored to address specific queries regarding sturgeon-chub-invertebrate dynamics in the lower Missouri River. Data include a simulated pallid sturgeon maximum weight over time under...
Summary from posterior distributions of multistate movement model for silver carp in the upper Mississippi River from 2014 to 2021 Summary from posterior distributions of multistate movement model for silver carp in the upper Mississippi River from 2014 to 2021
This data contains the mean and standard deviations for movement rates for silver carp in the upper Mississippi River 2014 and 2021. The data are summaries of the posterior distribution from a Bayesian multistate model described in Stanton et al. 2024 (https://doi.org/10.7717/peerj.17834). References: Stanton JC, Brey MK, Coulter AA, Stewart DR, Knights B. 2024. Bayesian multistate...
Summary of Detection Data for Breeding Common Loons in North-central Minnesota (2024) Summary of Detection Data for Breeding Common Loons in North-central Minnesota (2024)
The Deepwater Horizon oil spill on April 20, 2010 caused extensive injury to natural resources in the Gulf of Mexico, and Gavia immer (common loon) were negatively affected from the spill. The Open Ocean Trustee Implementation Group funded the project Restoration of Common Loons in Minnesota to restore common loons lost to the spill. In 2020–21, study lakes in a seven-county region in...
Summary of variations of specific conductance with altitude for selected groundwater monitoring wells, Saipan, Commonwealth of the Northern Mariana Islands Summary of variations of specific conductance with altitude for selected groundwater monitoring wells, Saipan, Commonwealth of the Northern Mariana Islands
This data release includes tabular summaries of specific conductance, temperature, and altitude (depth; CTD) and plots of specific conductance versus altitude at selected groundwater monitoring wells during July 2018–July 2024. The tabular summaries were developed using data retrieved from GeoLog Locator, an online database for quality-assured borehole geophysical data and accessible at...
Supplemental data for Over and Sherwood (2025), Washover and washout locations and landcover classifications after hurricanes Florence, Dorian, Harvey, Ike, and Sandy in North Carolina, Texas, and New York Supplemental data for Over and Sherwood (2025), Washover and washout locations and landcover classifications after hurricanes Florence, Dorian, Harvey, Ike, and Sandy in North Carolina, Texas, and New York
The data in this release support the journal article "Outwash events inhibit vegetation recovery and prolong coastal vulnerability". The research details the vegetation cover in washover and washout locations in North Carolina, Texas, and New York after hurricanes Florence, Dorian, Harvey, Ike, and Sandy. Aerial imagery observations indicate that washout sites create ponds and have a...
