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...

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...

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...

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.

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...

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.

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.

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...

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...

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...

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...

This U.S. Geological Survey (USGS) Data Release describes field methods, lab methods, and data for groundwater and soil gas samples collected in the vicinity of the Red Hill Bulk Fuel Storage Facility, O‘ahu, Hawai‘i, from September 2022 through April 2023. The Red Hill facility consists of 20 underground fuel storage tanks that can each hold approximately 12.5 million gallons of fuel...
