USGS and NOAA merge collections to create new high-resolution, broad-scale geologic maps of the seafloor

Release Date:

USGS and NOAA collaborate to create high-resolution maps on the Atlantic continental shelf between Delaware and Virginia.

The U.S. Geological Survey (USGS) and the National Oceanic Atmospheric Administration (NOAA) have collected sea floor mapping data on the Atlantic continental shelf between Delaware and Virginia over the past decade and a half. Although originally acquired for different objectives, the comprehensive coverage and variety of data (bathymetry, backscatter, imagery and physical samples) presents an opportunity to merge collections and create new high-resolution, broad-scale geologic maps of the seafloor using machine learning. These new geologic data products can be used to identify sediment sources, inform resource management, link seafloor environments to sediment texture, improve our understanding of the seafloor structure and sediment pathways, and demonstrate how ocean mapping resources can be useful beyond their original intent to maximize the footprint and scientific impact of a study.  Read the Geosciences article, Optimizing an Inner-Continental Shelf Geologic Framework Investigation through Data Repurposing and Machine Learning

Hurricane Sandy Response- Linking the Delmarva Peninsula's Geologic Framework to Coastal Vulnerability

The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy. In order to better constrain controls on coastal vulnerability and evolution, the region’s sediment sources, transport pathways and sediment sinks must be identified. This project defines the geologic framework of the Delmarva coastal system through...

High-resolution geophysical data collected along the Delmarva Peninsula 2014, U.S. Geological Survey Field Activity 2014-002-FA

 Data collected during the 2014 cruise include swath bathymetry, sidescan sonar, chirp and boomer seismic-reflection profiles, acoustic Doppler current profiler, and sample and bottom photograph data. Processed data in raster and vector format are released here for the swath bathymetry, sidescan sonar, and seismic-reflection profiles.
