Thiamine concentrations in lake trout eggs collected from the Great Lakes in 2019-20 Thiamine concentrations in lake trout eggs collected from the Great Lakes in 2019-20
Text files containing data regarding attributes of lake trout egg thiamine concentrations from sites in lakes Huron and Michigan collected during 2019-20, sampling site locations and quality assurance quality control values for comparison to previous years (2017-18) lake trout egg thiamine concentrations.
Thin section images of AMAX drill core from the Stillwater Complex, Montana Thin section images of AMAX drill core from the Stillwater Complex, Montana
This dataset includes photographic and micrographic images of thin sections of drill core from the Stillwater Complex, Montana, along with a shapefile representing the locations of the drill holes. The core was drilled in order to study contact-type copper and nickel sulfide mineralization in the Stillwater Complex. See data release https://doi.org/10.5066/p9w5kp8u for accompanying drill...
Thin section images of drill core and hand samples from the Stillwater Mine area, Stillwater Complex, Montana Thin section images of drill core and hand samples from the Stillwater Mine area, Stillwater Complex, Montana
This dataset includes photographic images of thin sections created from hand samples and drill core from the Stillwater Complex, Montana, along with a shapefile representing the locations of the underground samples and drill hole collars. The samples were collected and core was drilled in order to define platinum-group element resources associated with the J-M Reef at the Stillwater Mine...
Thin section images of drill core from the Chrome Lake area in the Stillwater Complex, Montana Thin section images of drill core from the Chrome Lake area in the Stillwater Complex, Montana
This dataset includes photographic images of thin sections of drill core from the Stillwater Complex, Montana, along with a shapefile representing the locations of the drill holes. The core was drilled in order to study contact-type copper and nickel sulfide mineralization in the Stillwater Complex. The images of the entire thin section, both in plane- and cross-polarized light, were...
Thin section images of drill core from the Crescent Creek area in the Stillwater Complex, Montana Thin section images of drill core from the Crescent Creek area in the Stillwater Complex, Montana
This dataset includes photographic images of thin sections of drill core from the Stillwater Complex, Montana, along with a shapefile representing the location of the drill hole. The core was drilled in order to study contact-type copper and nickel sulfide mineralization in the Stillwater Complex. The images of the entire thin section, both in plane- and cross-polarized light, were taken...
Thin section images of xenoliths from north of the Stillwater Complex, Montana Thin section images of xenoliths from north of the Stillwater Complex, Montana
This dataset includes photographic images of thin sections made from xenolith samples collected from the Sliderock Mountain and Susie Peak plutons, Montana, along with a shapefile representing the locations of the samples. The plutons are located north of the Stillwater Complex, Montana, which is exposed along the northern side of the Beartooth Mountains in Montana. To the north of the...
Three-dimensional grid of properties used to analyze induced seismicity recorded from 1991 to 2012 at Paradox Valley, Colorado Three-dimensional grid of properties used to analyze induced seismicity recorded from 1991 to 2012 at Paradox Valley, Colorado
Large numerical grid used for finite element and finite volume analysis of induced seismicity in Paradox Basin. The grid construction used the boundaries of three sub-horizontal surfaces; the topography, and the top and bottom of the production formation is determined from drilling and seismic reflection profiling, yielding the surface topography and thickness variations in these data...
Tidal Datums, Tidal Range, and Nuisance Flooding Levels for Chesapeake Bay and Delaware Bay Tidal Datums, Tidal Range, and Nuisance Flooding Levels for Chesapeake Bay and Delaware Bay
This U.S. Geological Survey data release provides data on spatial variations in tidal datums, tidal range, and nuisance flooding in Chesapeake Bay and Delaware Bay. Tidal datums are standard elevations that are defined based on average tidal water levels. Datums are used as references to measure local water levels and to delineate regions in coastal environments. Nuisance flooding refers...
Tidal flow dynamics at Sutter and Steamboat Sloughs in the Sacramento-San Joaquin Delta, CA in 2014 Tidal flow dynamics at Sutter and Steamboat Sloughs in the Sacramento-San Joaquin Delta, CA in 2014
The video shows a short animation of river flow dynamics (flow velocity vectors) over multiple tidal cycles.
Time Series of Autonomous Carbonate System Parameter Measurements in Eastern Gulf of Mexico near Tampa Bay, Florida, USA Time Series of Autonomous Carbonate System Parameter Measurements in Eastern Gulf of Mexico near Tampa Bay, Florida, USA
This data set contains time series measurements of carbonate system parameters including water temperature (degrees C), pressure (dbars), salinity, pHT (pH on the total scale), carbon dioxide (ppm), dissolved oxygen (milligrams/L), and photosynthetically active radiation (microEinsteins). These data were collected in the eastern Gulf of Mexico near Tampa Bay, Florida, at the University...
Time series of expected livestock forage biomass in the semi-arid grasslands of the western U.S. (2000-2018) Time series of expected livestock forage biomass in the semi-arid grasslands of the western U.S. (2000-2018)
Management and disturbances have significant effects on grassland forage production. When using satellite remote sensing to monitor climate impacts such as drought stress on annual forage production, minimizing these effects provides a clearer climate signal in the productivity data. The use of an ecosystem performance approach for assessment of seasonal and interannual climate impacts...
Time Series of Structure-from-Motion Products-Orthomosaics, Digital Elevation Models and Point Clouds: Little Dauphin Island and Pelican Island, Alabama, September 2018-April 2019 Time Series of Structure-from-Motion Products-Orthomosaics, Digital Elevation Models and Point Clouds: Little Dauphin Island and Pelican Island, Alabama, September 2018-April 2019
Barrier islands are dynamic environments that are gradually shaped by currents, waves, and tides under quiescent conditions, yet can evolve in the time scale of hours to days during hurricanes and other extreme storms. Small unmanned aircraft systems (sUAS) allow the opportunity for collecting topographic data for monitoring purposes, with a temporal resolution that is well-suited for...
