This dataset contains shoreline positions derived from available Landsat satellite imagery for two states (Oregon, and Washington) along the U.S. Pacific coast for the time period 1984 to 2023. An open-source toolbox, CoastSat (Vos and others, 2019a and 2019b), was used to classify coastal Landsat imagery and detect shorelines at the sub-pixel scale. Resulting shorelines are presented in...

Two digital video cameras were installed at Dorado, Puerto Rico (PR); camera 1 faced west alongshore and camera 2 faced northeast alongshore. Every hour during daylight hours, daily starting in August 2022, the cameras collected raw video and produced snapshots and time-averaged image products. This data release includes the necessary intrinsic orientation (IO) and extrinsic orientation...

This data release supports a study investigating the role of sulfur as a catalyst in thermal reaction kinetics, focusing on the effect of pyritic sulfur on early maturation and consequent hydrocarbon generation. Hydrous pyrolysis experiments were conducted on mixtures of gilsonite and pyrite in varying ratios. Untreated and thermally altered residues were analyzed for solid bitumen...

The West and Central African Rift System (WCARS) refers to the series of Cretaceous rift basins where commercial hydrocarbon accumulations have been discovered. The Babouri-Figuil Basin (BFB) is an area of interest in terms of petroleum prospecting related to the WCARS. Many researchers have identified potential petroleum source rocks in the BFB. However, most of these studies have...

The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB) and the Oka' Institute, constructed a Soil-Water-Balance (SWB) model of the eastern part of the Arbuckle-Simpson aquifer in south-central Oklahoma. The SWB model was used to estimate recharge to the eastern part of the Arbuckle-Simpson aquifer between January 2019 and December 2022 for...

This data release provides access to a low-altitude, aeromagnetic survey of a part of northwestern California. These data were acquired to support earthquake and tsunami hazard investigations and geologic mapping of the greater Trinidad area of northwestern California. Magnetic data are provided as a database and the residual magnetic intensity is provided as a grid.

This dataset contains study results examining the effect of road mortality on migrating salamanders along the Natchez Trace Parkway in Mississippi from 2012-2013. A combination of methods were used to assess the movement of salamanders to and from the breeding pond. Environmental variables such as air and water temperature, water salinity, and relative humidity were also collected during...

This dataset contains data from time-constrained visual encounter surveys conducted in the Atchafalaya River Basin in South Central Louisiana from February 2008 through July 2016. In addition, it contains vocalization data collected concurrently with the visual encounter surveys and data on presence of tadpoles and larvae. All participants in surveys are included in the dataset...

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...

A Cessna 182 fixed-wing aircraft equipped with a multispectral camera was used to collect aerial imagery of selected river reaches within the Willamette River Integrated Water Science basin in Oregon. On April 16-18, 2024, image acquisition was focused on four reaches of the Clackamas River. Photogrammetry techniques were applied to the images consisting of visible or red, green, and...

We used data from 2.5 years of A. canadensis observations in the San Luis Valley to examine their foraging patterns during spring and autumn migration. We counted cranes weekly or bi-weekly each season and year during roadside surveys. We determined crop type (alfalfa, barley, pasture, potatoes, other grain, and other) during roadside surveys. We also recorded tillage intensity for grain...

Sediment accumulation and transport negatively affect flood control, water supply, aquatic life, reclamation, and recreation (Angino and O’Brien, 1968) and are concerns of resource managers in the Kankakee River Basin of northern Indiana and throughout many regions of the United States. By relating continuously monitored water-quality data to discrete data collected from April 2016...
