Data

U. S. Geological Survey (USGS) scientists completed a data collection campaign from the 3rd of June to the 22nd of July in 2024, using various methods to record geomorphic and habitat indicators throughout 30 streams in the Maryland-Washington, DC-Virginia Developed Piedmont region. Field methods included GNSS surveys, gravelometer-based pebble count readings, visual assessments, and...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources of South America and the Caribbean. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment (NAGA) Project for the assessment of undiscovered oil and gas...

The database for the geology of the 7.5-minute Eagle Lake quadrangle consists of deformed and metamorphosed Mesoproterozoic gneisses of the Adirondack Highlands unconformably overlain by weakly deformed lower Paleozoic sedimentary rocks of the Champlain Valley. The Mesoproterozoic rocks occur on the eastern edge of the Adirondack Highlands and represent an extension of the Grenville...

Multiple surface geophysical methods were used to characterize the hydrogeology and potential groundwater flow pathways for spring discharge near Quitobaquito Spring, located in Organ Pipe Cactus National Monument, AZ. The direct-current resistivity method was used with an electrical resistivity tomography (ERT) survey along six line-locations to determine groundwater elevation...

To establish benthic conditions before construction of an Upper Mississippi River Restoration Program habitat restoration and enhancement project (HREP) in Navigation Pool 13, we sampled native freshwater mussels, tubers from watercelery (Vallisneria americana) plants, and surficial sediment with a stratified systematic survey design from 9/24/2024 to 10/4/2024. About 300 sites were...

This dataset contains paired in situ and satellite-derived water surface elevation (WSE) observations compiled to evaluate the accuracy of the Surface Water and Ocean Topography (SWOT) mission water surface elevation data over rivers and lakes. In situ WSE measurements were obtained from the U.S. Geological Survey (USGS), U.S. Bureau of Reclamation (BOR), Environment and Climate Change...

The U.S. Geological Survey (USGS) supports multiple efforts to understand and predict storm impacts to our nation’s coastlines . The first infrastructure line is defined as the seaward boundary of the first row of structures or roads in a coastal area and can be used to assess coastal vulnerability. The first infrastructure line as defined in this dataset represents a cross shore...

This data release provides continuous water quality measurements from five sites in different landscapes within the Nellie Juan River Basin, Alaska. For each site there are six to seven tables of water quality data: dissolved oxygen (DO), fluorescent dissolved organic matter (fDOM), pH, specific conductance, turbidity, water temperature, and water surface height.

This dataset includes freshwater drum age data from five study reaches of the Mississippi River and one study reach from the Illinois River as presented in the manuscript Life history traits and population dynamics of Freshwater Drum across large river gradients. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S...

Management of Grass Carp (Ctenopharyngodon Idella) has become of great interest to fisheries managers throughout multiple watersheds where they have become established. Grass Carp baits have been tested as part of an integrated pest management plan to aggregate fish and increase catchability. However, the habitats, water depth, and structures used by Grass Carp remain poorly...

The study compared the survival of zebra mussels and benthic macroinvertebrates after a 5-day treatment with carbon dioxide infusion under a tarp and a benthic mat. The study was conducted on Loon Lake, Benzie County, Michigan within Sleeping Bear Dunes National Lakeshore. The data include water quality (dissolved oxygen, pH, temperature) and water chemistry, zebra mussel mortality and...

The US Geological Survey's Upper Midwest Environmental Sciences Center, in coordination with the US Fish and Wildlife Service's (USFWS) Branch of Migratory Bird Surveys, worked to develop, survey, and deploy an advanced aerial photography boresight in the town of Bassville Park, Florida. The intention of this boresight is to provide an extensive array of high-accuracy ground control...
