High-Resolution Concurrent Bathymetric and Topographic Surveys of Lake Pushmataha, Choctaw Indian Reservation, East-Central Mississippi, December 2024 High-Resolution Concurrent Bathymetric and Topographic Surveys of Lake Pushmataha, Choctaw Indian Reservation, East-Central Mississippi, December 2024
In December 2024, the Lower Mississippi-Gulf Water Science Center (LMGWSC) conducted comprehensive field surveys of Lake Pushmataha, a central Mississippi reservoir owned by the Mississippi Band of Choctaw Indians (MBCI) and named in honor of Chief Pushmataha. These surveys aimed to provide high-resolution spatial data to support the Bureau of Indian Affairs (BIA) in designing and...
Estimated crop irrigation water use withdrawals in Harquahala Irrigation Non-Expansion Area Groundwater Basin, Arizona for 2024 Estimated crop irrigation water use withdrawals in Harquahala Irrigation Non-Expansion Area Groundwater Basin, Arizona for 2024
Observations of irrigated agricultural land within the Harquahala Irrigation Non-Expansion Area Groundwater Basin in Arizona. Crops were verified in situ twice in 2024, first on May 15th and again on Aug 29th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for...
Numerical simulations of lithospheric shortening on the ice-covered moons Europa and Enceladus Numerical simulations of lithospheric shortening on the ice-covered moons Europa and Enceladus
Jupiter’s moon Europa and Saturn’s moon Enceladus have many commonalities; however, the surfaces of the two moons bear little resemblance to each other. Significantly, although both moons show ample evidence of lithospheric extension (e.g., rifting), only Enceladus has obvious features formed by lithospheric shortening. We hypothesize that this difference is primarily caused by the...
Improved camera pointing and spacecraft ephemeris data for Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) images of the lunar poles. Improved camera pointing and spacecraft ephemeris data for Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) images of the lunar poles.
NASA’s lunar exploration objectives, which include both robotic and human missions to the surface, require data products with high spatial resolution and accuracy. Using rigorous photogrammetric methods, we have co-aligned thousands of high-resolution images from the Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) [Robbinson et al. 2010] of the lunar north and south...
Ephemeral Stream Channel Stability Data from the Grand Valley, Western Colorado, 2018-21 Ephemeral Stream Channel Stability Data from the Grand Valley, Western Colorado, 2018-21
This U.S. Geological Survey (USGS) data release provides the data used to predict areas with the greatest probability of ephemeral stream channel instability on north side of the Grand Valley in western Colorado, during 2018-20. The USGS developed a method for automatically extracting channel cross-section geometry from existing remotely sensed terrain models. Based on estimated flood...
Statewide base-flow estimates for Oregon, water years 1980–2023 Statewide base-flow estimates for Oregon, water years 1980–2023
Base flow, the groundwater contribution to streamflow, is beneficial data for analysis of groundwater-flow systems. This data release includes base-flow estimates and streamflow data for 471 Oregon streamgage sites. Categories of data include: (1) site information, (2) water year estimates of base flow and streamflow, and (3) daily estimates of base flow. Water-year base-flow estimates...
