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...

California Agricultural Land Use Estimates Derived from Pesticide Use Reporting Data California Agricultural Land Use Estimates Derived from Pesticide Use Reporting Data
Agricultural land use estimates are vital to understanding agricultural production, economic contributions, and water demands. A method to estimate spatially and temporally distributed agricultural land use was developed for California. Pesticide application records were processed to develop annual statewide estimates of agricultural land use at approximately 1-square mile resolution...
Low-Flow Statistic Equations and Supplementary Data for Massachusetts Low-Flow Statistic Equations and Supplementary Data for Massachusetts
The U.S. Geological Survey (USGS), in cooperation with the Massachusetts Department of Conservation and Recreation, Office of Water Resources, developed regional regression equations for estimating selected low-flow statistics in Massachusetts. This data release contains the datasets used in the regression analyses for the regional low-flow equations for the mainland area of...
Aerial Imagery and Structure-from-Motion Derived Data Products from an Aerial Digital Photographic Survey of 10 Islands in the Oregon Coast National Wildlife Refuge Complex, OR, USA Aerial Imagery and Structure-from-Motion Derived Data Products from an Aerial Digital Photographic Survey of 10 Islands in the Oregon Coast National Wildlife Refuge Complex, OR, USA
This release presents hi-resolution structure-from-motion (SfM) habitat imagery suitable for GIS. The U.S. Geological Survey (USGS) has developed SfM to become a low-cost technique for coastal change assessments. The software uses a combination of camera locations and ground control points to produce digital surface models (DSMs) and orthorectified imagery products. SfM products include...
Public-supply and industrial water withdrawals from the Sparta aquifer by parish in Louisiana, 2023 Public-supply and industrial water withdrawals from the Sparta aquifer by parish in Louisiana, 2023
Since 1975, annual water use for Louisiana has been published on a 5-year basis and is used for a variety of purposes. As the Sparta aquifer is a heavily used aquifer, is the sole source of groundwater for many parishes in Louisiana, and recent withdrawals have exceeded the Sparta’s natural recharge, a more frequent compilation of water usage for the Sparta aquifer in Louisiana is needed...
