Data and Tools

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.

National Digital Catalog

The National Digital Catalog, hosted on the USGS ScienceBase data infrastructure, serves as a repository for metadata describing geoscience assets preserved by USGS and state geological surveys. Web links, access instructions, and uploaded files provide direct access to the digital and physical resources for scientific investigations.

Marsh shorelines of the Massachusetts coast from 2013-14 topographic lidar data

The Massachusetts Office of Coastal Zone Management (CZM) launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the Massachusetts coast. This update included a marsh shoreline, which was defined to be the tonal difference between low- and high-marsh seen in ortho-photos. Further cooperation between CZM and the U.S. Geological Survey (USGS) has resulted in another...

Water surface elevations recorded by submerged water level loggers in off-channel features of the middle and upper Willamette River, Oregon, Summer, 2016

Water surface elevations within seven Willamette River off-channel features were measured using submerged pressure transducers. Transducers were installed from late May through mid-October, 2016. These pressure transducer data sets were collected to characterize relationships between Willamette River discharges and water surface elevations in off-channel features.

Collection, analysis, and age-dating of sediment cores from salt marshes on the south shore of Cape Cod, Massachusetts, from 2013 through 2014

Elevation of the marsh surface was measured with RTK-GPS to evaluate where the marsh falls within the current tidal frame. The historic marsh surface elevation was then reconstructed using the calculated age of each depth interval and its elevation, assuming that elevations within this shallow zone (less than 30 cm) have been preserved for the past century.

Continuous Bathymetry and Elevation Models of the Massachusetts Coastal Zone and Continental Shelf

Integrated terrain models covering 16,357 square kilometers of the Massachusetts coastal zone and offshore waters were built to provide a continuous elevation and bathymetry terrain model for ocean planning purposes.  A Triangulated Irregular Network was created from public-domain bathymetric and LiDAR data using the ArcGIS terrain-model framework.

Conceptual salt marsh units for wetland synthesis: Edwin B. Forsythe National Wildlife Refuge, New Jersey

The salt marsh complex of the Edwin B. Forsythe National Wildlife Refuge (EBFNWR), which spans over Great Bay, Little Egg Harbor, and Barnegat Bay (New Jersey, USA), was delineated to smaller, conceptual marsh units by geoprocessing of surface elevation data. Flow accumulation based on the relative elevation of each location is used to determine the ridge lines that separate each marsh unit....
