Developmental Stages of Grass Carp (Ctenopharyngodon idella) eggs in the Sandusky River (ver. 3.0, July 2020) Developmental Stages of Grass Carp (Ctenopharyngodon idella) eggs in the Sandusky River (ver. 3.0, July 2020)
Grass Carp Ctenopharyngodon idella was imported to the United States in the 1960s for research into its usefulness as a biocontrol agent for nuisance aquatic vegetation. Escapees and intentionally stocked individuals founded wild, spawning populations in the Mississippi River and tributaries to the Laurentian Great Lakes. USGS-led research on the Sandusky River, a tributary to Lake Erie
Diagnostic and field data from the Eastern Migratory Whooping Crane Population Diagnostic and field data from the Eastern Migratory Whooping Crane Population
Detailed data collected from the field and generated during diagnostic evaluation of whooping crane carcasses from the Eastern Migratory Population.
DIDSON video collection of Coastal Lake Erie Wetland, Lucas Co, Ohio in 2011 DIDSON video collection of Coastal Lake Erie Wetland, Lucas Co, Ohio in 2011
The data set includes quantitative fish abundance counts estimated from video data files collected by a Dual-frequency IDentification SONar (DIDSON) placed at the junction of a water control structure located between Pool 2B and Crane Creek (41.62133N, -83.20769W) within Ottawa National Wildlife Refuge (Lucas County, Ohio). One-hour-long video data files were used to estimate fish...
Differenced Normalized Burn Ratio (dNBR) data of wildfires in the Sky Island Mountains of the southwestern US and northern Mexico from 2011-2017 Differenced Normalized Burn Ratio (dNBR) data of wildfires in the Sky Island Mountains of the southwestern US and northern Mexico from 2011-2017
This dataset is composed of 97 Differenced Normalized Burn Ratio (dNBR) images. Each dNBR represents a rough measure of fire-related vegetation change for wildfires (>400 ha) that occurred in the Sky Island Mountains within the Madrean Archipelago Ecoregion of the United States and Northern Mexico. These fires occurred between 2011 and 2017 and were mapped using Landsat 7 and 8 satellite...
Differential Optical Absorption Spectroscopy data acquired during the 2018 rift eruption of Kilauea Volcano Differential Optical Absorption Spectroscopy data acquired during the 2018 rift eruption of Kilauea Volcano
A fissure eruption occurred in K?lauea Volcano?s Lower East Rift Zone (LERZ) from April to September 2018. During this event, volcanic gases were emitted from three active areas on the volcano. The most intense degassing occurred at the active fissures in the LERZ, thus causing parts of Hawai?i Island?s Puna district to be exposed to life-threatening sulfur dioxide (SO2) concentrations...
Digital Data for the Geology of the Mineral and Lake Anna West quadrangles, Virginia Digital Data for the Geology of the Mineral and Lake Anna West quadrangles, Virginia
This Data Release contains 1:24,000-scale geospatially-enabled geological data to accompany the Geology of the Mineral and Lake Anna West quadrangles, Virginia. The map product is a cooperator series publication and, as such, does not have a specific abstract. Geologic mapping for this map product was completed between 2014 and 2017, with most of the field work occurring between January...
Digital data for three-dimensional geologic framework model of the Rio San Jose groundwater basin, New Mexico Digital data for three-dimensional geologic framework model of the Rio San Jose groundwater basin, New Mexico
This data release contains a geospatial database related to a digital 3D geologic framework of the Rio San Jose watershed, New Mexico. The geospatial database contains two main data elements: (1) input data to the 3D framework model; (2) interpolated elevations and thicknesses of stratigraphic units as a cellular array. Input surface and subsurface data for 18 stratigraphic units have...
Digital database of the geologic map of Alamagan Volcano, northern Mariana Islands Digital database of the geologic map of Alamagan Volcano, northern Mariana Islands
Alamagan Volcano is a Quaternary stratovolcano along the Mariana Arc, an active subduction zone in the western Pacific Ocean. Although primarily submerged, its peak reaches above sea level, with subaerially-exposed volcanic deposits dating back through the Holocene to the late Pleistocene. These feature data represent such deposits and other geologic features of Alamagan Volcano...
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...
Digital Datasets Documenting Surface Fault Rupture and Ground Deformation Features Produced by the Ridgecrest M6.4 and M7.1 Earthquake Sequence of July 4 and 5, 2019 Digital Datasets Documenting Surface Fault Rupture and Ground Deformation Features Produced by the Ridgecrest M6.4 and M7.1 Earthquake Sequence of July 4 and 5, 2019
This product is a collection of digital data that document fault rupture and ground-deformation features produced by the Ridgecrest M6.4 and M7.1 earthquake sequence of July 4 and 5, 2019. These datasets are described and more fully discussed in Ponti and others (2020) (see External Resources Section below for the full reference). Included in this collection are: GIS Shapefile and KMZ...
Digital elevation model of K?lauea Volcano, Hawaii, based on July 2019 airborne lidar surveys Digital elevation model of K?lauea Volcano, Hawaii, based on July 2019 airborne lidar surveys
The 2018 eruption of Kilauea Volcano on the Island of Hawaii saw the collapse of a new, nested caldera at the volcano?s summit, and the inundation of 35.5 square kilometers (13.7 square miles) of the lower Puna District with lava. Between May and August, while the summit caldera collapsed, a lava channel extended 11 kilometers (7 miles) from fissure 8 in Leilani Estates to Kapoho Bay...
Digital elevation model of the Nehalem Bay near Wheeler, Oregon 2019 Digital elevation model of the Nehalem Bay near Wheeler, Oregon 2019
Bathymetric data were collected by the U.S. Geological Survey (USGS) in 2019 for approximately 2.2 square kilometers of the Nehalem Bay between the Highway 101 bridge and Nehalem Bay State Park (about 6.5 kilometers) near Wheeler, Oregon. The data were collected using a Trimble R8 Global Navigation Satellite System (GNSS) receiver combined with a Seafloor Systems Hydrolite TM single-beam...
