Data Release for Surficial Geology and Quaternary Tectonics of the Madison Valley and Fault Zone, Madison, Gallatin, and Beaverhead Counties, southwest Montana Data Release for Surficial Geology and Quaternary Tectonics of the Madison Valley and Fault Zone, Madison, Gallatin, and Beaverhead Counties, southwest Montana
The NNW-striking Madison fault zone is approximately 95 km in length, lying at the confluence of the northeast Basin and Range province and the Yellowstone tectonic parabola. The fault zone consists primarily of west-dipping normal faults with east-dipping antithetic faults, which create the Madison Valley graben and several northeast-trending intra-basin faults. The Madison fault zone...
Sea Otter Aerial Survey Data from Western Prince William Sound, Alaska, 2022 Sea Otter Aerial Survey Data from Western Prince William Sound, Alaska, 2022
This dataset consists of three tables related to abundance and distribution of northern sea otters (Enhydra lutris kenyoni) in western Prince William Sound, Alaska, based on data collected during a series of population-wide aerial surveys in June 2022. The dataset consists of: (1) sea otter counts along strip transects, (2) sea otter counts in Intensive Search Unit (ISU) within the...
Bedrock geologic map database for the Blanca Peak, Walsenburg, Trinidad, and Alamosa 30' x 60' quadrangles, Colorado Bedrock geologic map database for the Blanca Peak, Walsenburg, Trinidad, and Alamosa 30' x 60' quadrangles, Colorado
This data release presents geologic map data for the bedrock geology of the Blanca Peak, Walsenburg, Trinidad, and Alamosa 30' x 60' quadrangles, Colorado. Geologic mapping incorporates new interpretive contributions and compilation from published geologic map data sources primarily ranging from 1:24,000 to 1:50,000 scale. Much of the geology incorporated from published geologic maps is...
Data Release for Luminescence: OSL Data and Ages in support of the Surficial Geology and Quaternary Fault Map of the Las Vegas Valley, Clark County, Nevada Data Release for Luminescence: OSL Data and Ages in support of the Surficial Geology and Quaternary Fault Map of the Las Vegas Valley, Clark County, Nevada
The data release includes 35 new luminescence ages and 3 new radiocarbon ages. The new age data further brackets the ages of the Las Vegas basin Quaternary stratigraphy and provide new constraints on the timing of Quaternary fault activity.
Grain-size analysis data from sediment samples in support of oceanographic and water-quality measurements in the nearshore zone of Sandy Neck Beach, Cape Cod Bay, Massachusetts, collected in March and April, 2021 Grain-size analysis data from sediment samples in support of oceanographic and water-quality measurements in the nearshore zone of Sandy Neck Beach, Cape Cod Bay, Massachusetts, collected in March and April, 2021
The U.S. Geological Survey Woods Hole Coastal and Marine Science Center collected data to assess cross-shore sediment transport prediction techniques in coastal models for a wave-dominated sandy coast. A quadpod was deployed on the seafloor in the nearshore zone of Sandy Neck Beach, Cape Cod Bay, MA in March 2021 to analyze water velocities near the seabed and the response of the seabed...
Eelgrass (Zostera marina) Percent Cover Data from Katmai National Park and Preserve, Kenai Fjords National Park, and Prince William Sound, Alaska Eelgrass (Zostera marina) Percent Cover Data from Katmai National Park and Preserve, Kenai Fjords National Park, and Prince William Sound, Alaska
These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program, nearshore monitoring component. The dataset has one comma separated values (.csv) table with estimates of eelgrass (Zostera marina) percent cover. Eelgrass cover was estimated from sonar and video drop cameras deployed from boats following prescribed survey transects.
Nesting Period Data for Black Brant (Branta bernicla nigricans) in Alaska Nesting Period Data for Black Brant (Branta bernicla nigricans) in Alaska
This data package contains one table with nest initiation and end dates and clutch sizes from Black Brant (Branta bernicla nigricans) at two breeding colonies in Alaska. Data include nesting period determined by either nest visits or light-level data recorded by geolocators attached tarsal bands.
Tracking Data for Black Brant (Branta bernicla nigricans) Tracking Data for Black Brant (Branta bernicla nigricans)
This data release includes 1 child item with tracking data for Black Brant, a goose species that breeds in coastal areas of Alaska, northwestern Canada, and northeastern Russia and winters along coastal areas of North America from western Alaska to Mexico. Child Item 1: "Light-Level Geolocator Tracking Data for Black Brant (Branta bernicla nigricans)" -- Tracking data collected from...
Map data for a landslide inventory of the northwestern part of Vicksburg National Military Park, Mississippi Map data for a landslide inventory of the northwestern part of Vicksburg National Military Park, Mississippi
Vicksburg National Military Park (VICK) is in western Mississippi, situated on the loess bluffs flanking the Mississippi River. These bluffs are comprised of an accumulation of windblown silt-rich sediments, known as loess, which overlays the Oligocene Vicksburg Group. The loess deposits are thick (up to 30 meters) and easily eroded, creating deep ravines and steeply sloped elongated...
Bridge-Site Study Data for Selected Highway Crossings in Mississippi, 2023 Bridge-Site Study Data for Selected Highway Crossings in Mississippi, 2023
The U.S. Geological Survey (USGS) works closely with the Mississippi Department of Transportation (MDOT) to provide information to be used by the MDOT for design of highway-drainage structures. MDOT spends millions of dollars annually for highway construction. Streamflow records, hydrologic analyses of basins, and hydraulic analyses of flooding potential at proposed highway crossings...
Results from additional dynamic cone penetration testing of soils on the Utuado Batholith, upland and dissected terrains, Puerto Rico - June 2022 Results from additional dynamic cone penetration testing of soils on the Utuado Batholith, upland and dissected terrains, Puerto Rico - June 2022
A Smart Dynamic Cone Penetrometer (DCP) system allows for the partially automated collection of cone penetrometer data (CPT) to determine mechanical properties of soil along a vertical profile. A smart DCP system was used to collect soil penetration-with-depth values alongside 12 soil pits dug in the Utuado Batholith, a late Cretaceous age granodiorite pluton located on the northern...
