Temperature and geophysical data collected along the Quashnet River, Mashpee/Falmouth MA (ver. 2.0, March 2020) Temperature and geophysical data collected along the Quashnet River, Mashpee/Falmouth MA (ver. 2.0, March 2020)
The temperature and surface geophysical data contained in this release have primarily been collected to support groundwater/surface water methods development, and to characterize the hydrogeological controls on native brook trout habitat. All data have been collected since 2010 along the Quashnet River corridor located on Cape Cod, MA, USA. Cape Cod is a peninsula in southeastern coastal
Thermal infrared and photogrammetric data collected by drone for hydrogeologic characterization around two US Geological Survey Next Generation Water Observing Systems stream gage locations near Claryville, NY, USA Thermal infrared and photogrammetric data collected by drone for hydrogeologic characterization around two US Geological Survey Next Generation Water Observing Systems stream gage locations near Claryville, NY, USA
The U.S. Geological Survey (USGS) collected low-altitude (typically 200-350 ft above land surface) airborne thermal infrared, and visual imagery data via a multirotor, small unoccupied aircraft system (UAS or 'drone') deployed along the river corridor encompassing two U.S. Geological Survey Next Generation Water Observing Systems (NGWOS) stream gage locations near Claryville, NY, USA...
Geospatial Datasets for the Flood-Inundation Study of Little Calumet River from Lansing to South Holland, Illinois, 2020 Geospatial Datasets for the Flood-Inundation Study of Little Calumet River from Lansing to South Holland, Illinois, 2020
Digital flood-inundation maps for about an 8-mile reach of the Little Calumet River, Illinois, were created by the U.S. Geological Survey (USGS) in cooperation with the U.S. Army Corps of Engineers. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Program website at https://www.usgs.gov/mission-areas/water-resources/science/flood-inundation...
Surface Geophysical data collected along Blacktail Creek in June 2017 near Williston, North Dakota, USA Surface Geophysical data collected along Blacktail Creek in June 2017 near Williston, North Dakota, USA
The extraction of unconventional oil and gas (UOG) resources often produces highly saline waste waters, which can be released to the river corridor environment during spills and pipe leakage. In North Dakota, USA more than 8,000 spills were recorded from 2008-2015, and more than half of those spills were related to pipelines. Data collected for this study were related to UOG wastewater...
Aerial imagery and photogrammetric products from unmanned aerial systems (UAS) flights over the Lake Ontario shoreline at Chimney Bluffs, New York, July 14, 2017 Aerial imagery and photogrammetric products from unmanned aerial systems (UAS) flights over the Lake Ontario shoreline at Chimney Bluffs, New York, July 14, 2017
Low-altitude (80-100 meters above ground level) digital images were obtained from a camera mounted on a 3DR Solo quadcopter, a small unmanned aerial system (UAS), in three locations along the Lake Ontario shoreline in New York during July 2017. These data were collected to document and monitor effects of high lake levels, including shoreline erosion, inundation, and property damage in...
Historical Bathymetry in the Mississippi-Alabama Coastal Region: Bathymetric Soundings, Gridded Digital Elevation Model, and Hydrographic Sheets Historical Bathymetry in the Mississippi-Alabama Coastal Region: Bathymetric Soundings, Gridded Digital Elevation Model, and Hydrographic Sheets
Hydrographic sheets (H-sheets) produced by the National Ocean Service (NOS) during the 1800s provide historic sounding (water depth) measurements of coastal areas. The data can be vectorized into a geographic information system (GIS), adjusted to a modern vertical datum, and converted into a digital elevation model to provide an interpretation of the historic seafloor elevation. These...
Ecological parameters in the Elwha River estuary before and during dam removal (ver. 2.0, August 2020) Ecological parameters in the Elwha River estuary before and during dam removal (ver. 2.0, August 2020)
The Elwha and Glines Canyon dams were removed from the Elwha River in Washington State from 2011 to 2014. We collected data for a variety of metrics in the estuary and on the river delta before (2006-2011) and during (2012-2014) dam removal to assess how increased sediment transport and deposition affected habitats, vegetation, invertebrates, and fish.
Pedestrian tsunami evacuation results for three California probabilistic tsunami hazard zones and four travel speeds (shapefiles) and impaired walk travel times for all zones by parcel land-use and flow depth class (tables) Pedestrian tsunami evacuation results for three California probabilistic tsunami hazard zones and four travel speeds (shapefiles) and impaired walk travel times for all zones by parcel land-use and flow depth class (tables)
These datasets supports the conclusions in the journal article entitled "Variations in community evacuation potential related to average return periods in probabilistic tsunami hazard analysis" as described in the abstract below: Tsunami risk management requires strategies that can address multiple sources with different recurrence intervals, wave-arrival times, and inundation extents
Digital datasets documenting subsurface data locations, topographic metrics, fault scarp mapping, and revised fault network for Crowley's Ridge, New Madrid Seismic Zone Digital datasets documenting subsurface data locations, topographic metrics, fault scarp mapping, and revised fault network for Crowley's Ridge, New Madrid Seismic Zone
This release provides the data and interpretations supporting evidence of late Quaternary faulting along Crowleys Ridge in the New Madrid seismic zone. The release includes location information for seismic reflection and airborne electromagnetic (AEM) data over Crowleys Ridge, a table of topographic metrics derived from analysis of the 10m National Elevation Dataset (NED) digital...
Eelgrass distributions and bathymetry of the Nisqually River delta, Washington Eelgrass distributions and bathymetry of the Nisqually River delta, Washington
This data release presents eelgrass distributions and bathymetric data from repeated surveys performed on the Nisqually River delta to document interannual changes in eelgrass abundance and coastal morphology following the removal of dikes in 2009 that restored tidal processes to over 300 ha of former freshwater wetlands. Survey operations were conducted by a team of scientists from the...
Dependence of sedimentation behavior on pore-fluid chemistry for sediment collected offshore South Korea during the Second Ulleung Basin Gas Hydrate Expedition, UBGH2 Dependence of sedimentation behavior on pore-fluid chemistry for sediment collected offshore South Korea during the Second Ulleung Basin Gas Hydrate Expedition, UBGH2
One goal of Korea?s second Ulleung Basin Gas Hydrate Expedition, UBGH2, is to examine geotechnical properties of the marine sediment associated with methane gas hydrate occurrences found offshore eastern Korea in the Ulleung Basin, East Sea. Methane gas hydrate is a naturally occurring crystalline solid that sequesters methane in individual molecular cages formed by a lattice of water...
Hawaii Island, Hawaiian hoary bat roosting ecology and detection 2018-2019 Hawaii Island, Hawaiian hoary bat roosting ecology and detection 2018-2019
The Hawaiian hoary bat (Lasiurus cinereus semotus), a federally and state listed endangered subspecies, is the only extant native terrestrial mammal in the Hawaiian archipelago. It is an insectivorous, solitary and foliage-roosting species that generally roosts alone or in mother-pup family groups. A total of 58 bats (17 female; 41 male; 56 adult; 2 juvenile) were captured at multiple...
