Development and application of a coastal change likelihood assessment for the northeast region, Maine to Virginia

Coastal resources are increasingly affected by erosion, extreme weather events, sea level rise, tidal flooding, and other potential hazards related to climate change. These hazards have varying effects on coastal landscapes because of the compounding of geologic, oceanographic, ecologic, and socioeconomic factors that exist at a given location. An assessment framework is introduced in this report

Collections management plan for the U.S. Geological Survey Woods Hole Coastal and Marine Science Center samples repository

Since 2002, the Woods Hole Coastal and Marine Science Center Samples Repository has been supporting U.S. Geological Survey research by providing secure storage for geological, geochemical, and biological samples, organizing and actively inventorying these sample collections, and providing researchers access to these scientific collections for study and reuse. Over the years, storage facilities ha

Deep learning for pockmark detection: Implications for quantitative seafloor characterization

Occurring globally, pockmarks are seafloor depressions associated with seabed fluid escape. Pockmark ubiquity and morphologic heterogeneity result in an irregular seafloor that can be difficult to quantitatively describe. To address this challenge, we test the hypothesis that deep-learning based object detection and segmentation can be used to develop data-driven models for pockmark identification

Coastal Change Likelihood

The U.S. Geological Survey, in partnership with the National Park Service through the Natural Resource Preservation Program, developed the Coastal Change Likelihood (CCL) assessment to determine the future likelihood of coastal change along U.S. coastlines in the next decade. The Northeast United States, from Maine to Virginia, was selected for a proof-of-concept pilot study.

Digital Shoreline Analysis System (DSAS)

Computer Software for Calculating Shoreline Change (or positional change of a boundary over time) The Digital Shoreline Analysis System (DSAS) v5 software is an add-in to Esri ArcGIS desktop (10.4-10.7+) that enables a user to calculate rate-of-change statistics from multiple historical shoreline positions. It provides an automated method for establishing measurement locations, performs rate...

Delineating the U.S. Extended Continental Shelf

The United States has an interest in knowing the full extent of its continental shelf beyond 200 nautical miles from shore (called the extended continental shelf, or ECS) so that it can better protect, manage and use the resources of the seabed and subsoil contained therein. The USGS contributes to the ECS effort through membership and leadership on the interagency U.S. ECS Task Force, a group...
