The U.S. Geological Survey (USGS), in cooperation with the Montana Department of Transportation (MDT), collected water-surface profile data at selected highway bridges in Montana. The water-surface profile data characterizes the water-surface elevation and slope upstream and downstream of a bridge. Water-surface profile data were typically obtained for one side of the stream by surveying...

The U.S. Geological Survey (USGS), in cooperation with the Montana Department of Transportation (MDT), collected various data at selected bridges in Montana. The data collected in the field included streambed cross-section data, longitudinal streambed profile data, and water-surface profile data. Efforts included overlaying pier structure geometry on the plots to demonstrate the position...

The U.S. Geological Survey (USGS), in cooperation with the Montana Department of Transportation (MDT), collected longitudinal streambed profile data along the sides of piers at selected bridges in Montana. The streambed profile data extends upstream and downstream of piers so that local pier scour effects might be distinguished from more general geomorphic scour processes. Two or more...

The U.S. Geological Survey (USGS), in cooperation with the Montana Department of Transportation (MDT), collected channel cross-section geometry data on the upstream and downstream sides of selected highway bridges in Montana. The cross-section data typically extend the full width of the streambed at the bridge opening and up the abutments so that local pier scour effects and more general

The U.S. Geological Survey (USGS) provides Level-2 Provisional Aquatic Reflectance (AR) Products through EROS Science Processing Architecture (ESPA) On-Demand Interface for the Collection 2 Landsat 8-9 archive. This dataset includes n=742 provisional AR products for the visible and near-infrared (VNIR) bands for the Operational Land Imager (OLI) sensor at 30 meters resolution coincident...

Observations of irrigated agricultural land within the McMullen Valley Groundwater Basin in Arizona. Crops were verified in situ four times in 2024 first on May 2nd, then on Aug 30th, Sep 10th, and finally on Dec 4th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery...

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...
