Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Data for Reaction Kinetics and Catalytic Effects of Sulfides in Early Mature Hydrocarbon Generation using Hydrous Pyrolysis Data for Reaction Kinetics and Catalytic Effects of Sulfides in Early Mature Hydrocarbon Generation using Hydrous Pyrolysis
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...
Total organic carbon and programmed temperature pyrolysis data with calculated thermal maturity parameters for Babouri-Figuil Basin samples Total organic carbon and programmed temperature pyrolysis data with calculated thermal maturity parameters for Babouri-Figuil Basin samples
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...
Adaptive capacity of the Northern California/Southern Oregon DPS of Fisher (Pekania pennanti) Adaptive capacity of the Northern California/Southern Oregon DPS of Fisher (Pekania pennanti)
An assessment of the adaptive capacity of the NCSO Fisher (Pekania pennanti) that uses 37 factors, grouped by related characteristics: distribution, movement, evolutionary potential, ecological role, abiotic niche, life history, and demography. For each factor, species can be evaluated on a simple “low–moderate–high” scale, with criteria designed to accommodate either quantitative or...
Soil-Water-Balance model and data for Phase 1 (2003–08) and Phase 2 (2018–23) hydrologic and water-budget analyses of the eastern part of the Arbuckle-Simpson aquifer, south-central Oklahoma, 2019–22 Soil-Water-Balance model and data for Phase 1 (2003–08) and Phase 2 (2018–23) hydrologic and water-budget analyses of the eastern part of the Arbuckle-Simpson aquifer, south-central Oklahoma, 2019–22
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...
Data from Paleocene-Eocene sediments of three cores in the Salisbury Embayment, Maryland and Virginia Data from Paleocene-Eocene sediments of three cores in the Salisbury Embayment, Maryland and Virginia
The Surprise Hill core was drilled on the Northern Neck, Northumberland County, Virginia. The studied section consists of glauconitic quartz sands of the upper Paleocene Aquia Formation and silty clays of the lower Eocene Marlboro Clay. Data from this core were compared to the previously documented South Dover Bridge and Howards Tract cores from Maryland. The purpose of this study was to...
Detailed Aeromagnetic Survey of the Trinidad Area, California Detailed Aeromagnetic Survey of the Trinidad Area, California
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.
