Science Datasets
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Calcium, magnesium and total dissolved solids data as well as modeled salinity and mass balance estimates for Lake Powell, 1952-2017
These data were compiled to quantify the role of Lake Powell in modulating salinity and reducing overall salt flux from the Upper Colorado River Basin downstream. In addition, these data were used to infer summertime calcite precipitation in Lake Powell (the major proposed sink for salt within the system). The Lake Powell Calcium Magnesium data contains summertime surface water calcium an...
Location and analyses of sediment samples collected on Stellwagen Bank off Boston, Massachusetts from November 5, 2013 to April 30, 2019 on U.S. Geological Survey field activities
These data are part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary (SBNMS) region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics.
Sea-floor sediment samples, seabed imagery, and CTD data collected on Stellwagen Bank, in May 2017, U.S. Geological Survey Field Activity 2017-030-FA
This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics
Barrier island geomorphology and shorebird habitat metrics: Sixteen sites on the U.S. Atlantic Coast, 2013–2014
This data release contains the extracted metrics of barrier island geomorphology and spatial data layers of habitat characteristics that are input to Bayesian networks for piping plover habitat availability and barrier island geomorphology. These datasets and models are being developed for sites along the northeastern coast of the United States.
Total organic carbon and pyrolysis analysis data for the U.S. Geological Survey Alcova AR-1-13 core hole, Natrona County, Wyoming
In 2013 the U.S. Geological Survey (USGS) drilled a continuous core in the southeastern part of the Wind River Basin, Wyoming to evaluate the source rock potential of the Lower and lowermost Upper Cretaceous marine shales . The well, named the Alcova Reservoir AR–1–13, located on the northeast flank of the Alcova anticline was spud in the lower part of the Frontier Form
Geochemical analyses of bauxite and associated rocks from the Arkansas bauxite region, central Arkansas
This data release compiles major and trace element analytical results of samples of bauxite (aluminum ore) and associated rocks collected from the Arkansas bauxite region, located near the center of Arkansas in Pulaski and Saline Counties. Samples were collected by the U.S. Geological Survey (USGS) in April 2018 as part of the USGS' focus on increased understanding of the United State
Select pipe-flow monitoring data from RecoveryPark in Detroit, MI (2015–2016)
This dataset includes pipe-flow monitoring data in sewers used to analyze the water budget at RecoveryPark in Detroit, Michigan. These are provided as 3 text *.csv files at sewer locations that drain the study area.
