Data

Observations of irrigated agricultural land within the Sierra Vista Groundwater Subbasin of the Upper San Pedro Groundwater Basin in Arizona. Crops were verified in situ once in 2024 on Sep 11th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizona and...

Tephra samples from the Kulanaokuaiki Tephra Member (400 to 1000 C.E.) of the Uwēkahuna Ash (200 B.C.E. to 1000 C.E.) were sampled from Kīlauea volcano, Island of Hawai‘i. Samples were analyzed by dynamic imaging analysis using Microtrac CAMSIZER P4 and X2 instruments for grain shape and Anton nitrogen pycnometer instruments for density in the U.S. Geological Survey - Hawaiian Volcano...

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...

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...

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...

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...

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...

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...

Groundwater, surface-water, and associated quality assurance samples were collected across western Cape Cod, Massachusetts and analyzed for per- and polyfluoroalkyl substances (PFAS) from September 2019 through November 2024. Water-quality properties measured at the time of sample collection included pH, specific conductance, temperature, and dissolved oxygen. Samples were also analyzed...

Observations of irrigated agricultural land within the Douglas Active Management Area Groundwater Basin in Arizona. Crops were verified in situ twice in 2024, first on May 28th and again on Aug 9th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizona and...

Geospatial datasets related to 6PPD-quinone, a compound intended to increase the life span of tires, were acquired and integrated into a relative heat index framework across the conterminous United States. 6PPD-quinone is known to be the cause of Coho Salmon kills following storm events, and more is being learned about the impacts it may have on other species. Sources and influential...

This dataset provides information on aquatic invertebrate composition from ponds (n = 16; surface area 0.02 km2) and lakes (n =16, surface area > 0.10 km2) on the central Arctic Coastal Plain of Alaska. Ponds and lakes were selected for sampling as part of a larger study of Arctic water body food webs. Details on the study area and findings are published in Laske et al. 2018 and Laske et...
