Surveyed coordinates and elevations in a 2020 resurvey of previously established cross sections on the Green River between Jensen and Ouray, Utah Surveyed coordinates and elevations in a 2020 resurvey of previously established cross sections on the Green River between Jensen and Ouray, Utah
These data were compiled for/to National Park Service and Upper Colorado River Endangered Fish Recovery Program. Objective(s) of our study were to resurvey previously established cross sections on the Green River, Utah, in, and upstream, from Ouray National Wildlife Refuge to document changes in channel width, depth, and cross-sectional area. These data represent the 2020 resurvey...
Mineralogy, strontium (87Sr/86Sr), oxygen (18O/16O) and carbon (13C/12C) isotope composition, elemental concentrations, and U-Th disequilibrium ages for travertine deposits from various locations in Yellowstone National Park, USA Mineralogy, strontium (87Sr/86Sr), oxygen (18O/16O) and carbon (13C/12C) isotope composition, elemental concentrations, and U-Th disequilibrium ages for travertine deposits from various locations in Yellowstone National Park, USA
Chemical changes in hot springs, as recorded by thermal waters and their mineral deposits, provide a window into the evolution of Yellowstone’s postglacial hydrothermal system. Travertine precipitated from thermal waters provide a record of chemical changes through time because they can be dated using U-series disequilibrium geochronology. These temporal data, along with measured...
Machine learning with satellite imagery to document the historical transition from topographic to dense sub-surface agricultural drainage networks (tile drains) Machine learning with satellite imagery to document the historical transition from topographic to dense sub-surface agricultural drainage networks (tile drains)
Image library of (1) tile-drained landscapes and (2) tile-drain types that will be used for a machine-learning model workflow that identifies (1) tile-drained landscapes and (2) differentiates two types of tile-drained areas visible in satellite imagery. These images were sourced from WorldView and Quickbird satellite imagery (copyright DigitalGlobe) and cropped to features of interest...
Thermal camera data for the summit of Kīlauea Volcano, 2019–2022 Thermal camera data for the summit of Kīlauea Volcano, 2019–2022
Following the 2018 collapses of the caldera floor at the summit of Kīlauea Volcano (Anderson and others, 2019; Neal and others, 2019), the enlarged and deepened depression hosted a variety of volcanic activity between 2019 and 2022. These events included an unprecedented water lake and two prolonged episodes of lava lake activity. This data release includes images from a stationary...
Elevation of the lava lake in Halemaʻumaʻu crater, Kīlauea Volcano, from 2009 to 2018 Elevation of the lava lake in Halemaʻumaʻu crater, Kīlauea Volcano, from 2009 to 2018
This data release includes measurements of the surface elevation of the lava lake within Halemaʻumaʻu crater, at the summit of Kīlauea Volcano, during the 2008-2018 summit eruption (Patrick and others, 2021). The data were measured by several instruments (laser rangefinder, webcams, lidar) and are compiled here to provide the most complete dataset yet available on the elevation of...
Colorimeter data for the summit water lake at Kīlauea Volcano, Island of Hawaiʻi, 2020 Colorimeter data for the summit water lake at Kīlauea Volcano, Island of Hawaiʻi, 2020
In 2018, a large effusive eruption on the lower flank of Kīlauea Volcano was associated with collapse and subsidence of the summit caldera floor (Neal and others, 2019). The bottom of Halemaʻumaʻu, a crater nested within the summit caldera, subsided by more than 500 m. In July 2019, water was observed ponding on the deepest part of the Halemaʻumaʻu crater floor and the water rose and...
