USGS National and Global Oil and Gas Assessment Project—Gulf Coast Mesozoic Province, Haynesville Formation Water and Proppant Assessment: Assessment Input Tables and Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project—Gulf Coast Mesozoic Province, Haynesville Formation Water and Proppant Assessment: Assessment Input Tables and Fact Sheet Data Tables
The input and results tables provide a record of the complete input and output values required for the quantitative assessment of water and proppant associated with oil and gas production for the continuous oil and gas resource in a geologically defined Assessment Unit. The same input form template is used for all such assessments. Each USGS water and proppant assessment builds from a...
Sierra Nevada Ecoregion LiDAR and Fuels Data, Collected in 2025 Sierra Nevada Ecoregion LiDAR and Fuels Data, Collected in 2025
Vegetation structure and fuels data are essential for understanding fire behavior following management treatments such as mechanical thinning and prescribed burning. To evaluate these processes, 133 plots were established between July 17 and September 21, 2025 across national forests and parks in the Sierra Nevada. These plots consisted of treated and untreated areas for comparison...
Southern Beaufort Sea Female Polar Bear Blood-Based Analyte Data, 1982-1985 Southern Beaufort Sea Female Polar Bear Blood-Based Analyte Data, 1982-1985
This dataset is one table with data collected and derived from female polar bears sampled in Alaska's southern Beaufort Sea during 1982-1985. Collected data includes demographic information. Derived data includes blood-based analyte values determined from serum samples. Serum samples were analyzed in 1986 by Evergreen Professional Services (Bothell, WA, USA). It is believed that a...
Data release for Geochemical evidence for the origin of late Quaternary loess, Seward Peninsula, Alaska Data release for Geochemical evidence for the origin of late Quaternary loess, Seward Peninsula, Alaska
Loess is the most widespread surficial deposit in the state of Alaska. Although loess of last-glacial age is common in mid-continental North America, records of last-glacial loess in Alaska have been elusive. Here we report a record of last-glacial loess on the Seward Peninsula, along with studies of a transect of loess localities also thought to date to the last glacial period. Highly...
Effects of restoration treatments at the piñon-juniper/ponderosa pine in northern New Mexico Effects of restoration treatments at the piñon-juniper/ponderosa pine in northern New Mexico
This dataset includes multiple data types from long-term monitoring and research on Rowe Mesa, NM, including data on surface fuels, ground cover, overstory tree metrics, regeneration, and tree-ring widths before and after burning and thinning treatments from 2005-2024. This data release includes 8 CSV files: DBH_DSH_conversion_data.csv (data used to create a regression of tree diameters...
Updated Estimates of Water Budget Components for the Mississippi Embayment Region Using a Soil-Water-Balance Model, 2000–2024 Updated Estimates of Water Budget Components for the Mississippi Embayment Region Using a Soil-Water-Balance Model, 2000–2024
This item provides Soil-Water-Balance (SWB) model input and output of a water budget simulation for the Mississippi Embayment Regional Aquifer System (MERAS) during the period 2000 to 2024. The output files include gridded daily data (1-kilometer resolution) for net infiltration (potential groundwater recharge), rejected net infiltration, interception, runoff, runoff outside (runoff that...
