Tracking Coastal Change with Photogrammetry

Monitoring coastal changes is important for the millions of people that live along coasts in the United States, particularly as climate change hastens coastal erosion by raising sea levels and fueling powerful storms. The USGS uses remote-sensing technologies—such as aerial photography, satellite imagery, structure-from-motion photogrammetry, and lidar (laser-based surveying)—to measure coastal change along U.S. shorelines. Powerful storms in January 2023 caused extensive damage to California’s coasts. USGS photogrammetry data, processed into accurate orthomosaics (essentially numerous photos stitched together) of the coastal landscape, show the erosional effects of these storms.

Sea-floor Mapping by the Woods Hole Coastal and Marine Science Center

Map of the US east coast, displaying sea-floor mapping achievements from 2022 — The year of 2022 was big for the Sea-Floor Mapping Group at the Woods Hole Coastal and Marine Science Center! These data were collected as part of a collaborative research program and include data collected by USGS and our partners. As the map shows, sea floor mapping was conducted in the Gulf of Mexico, Chesapeake Bay, Stellwagen Bank National Marine Sanctuary, Nantucket Sound, and other locations in the Atlantic Ocean.

As part of the Stakeholder Engagement for Natural Hazards Investigations in the Caribbean project, Meaghan Emory and Drs. Legna Torres-Garcia and Donya Frank-Gilchrist of the St. Petersburg Coastal and Marine Science Center engaged with stakeholders and explored potential partnerships across Caribbean nations and territories to further enhance USGS natural hazards research at the Southeast and Caribbean Disaster Resilience Partnership (SCDRP) annual meeting in Miami, Florida in January 2023.

Sediment Transport in San Francisco Bay

The Sacramento and San Joaquin Rivers deliver half the amount of sediment they did 50 years ago to San Francisco Bay. Just as sea-level rise is accelerating, the demand for sediment is growing. The amount of sediment supplied to estuaries is important to the fate of shallow water habitats, including mudflats and tidal marshes. In San Francisco Bay, U.S. Geological Survey scientists and collaborators are investigating the influence of tides, waves, and water levels on sediment delivery and deposition in wave-exposed tidal salt marshes.
