Woods Hole scientists surveyed Head of the Meadow Beach and Marconi Beach using a heli-kite, camera, and photogrammetry for the beach and bluffs, and an autonomous boat with GPS and sonar for the offshore portion. This work resulted in two data releases.

The Coastal and Estuarine Dynamics group at the WHCMSC maintained cameras along the Cape Cod National Seashore at Head of the Meadow Beach, North Truro, Massachusetts and Marconi Beach, Wellfleet, Massachusetts. The cameras are used to validate Total Water Level and Coastal Change forecasts.

Aerial imagery collected by airplane in the Outer Banks of North Carolina continued in FY22 as part of rapid response to storms and recovery monitoring after Hurricane Florence (2018) and Dorian (2019). Analysis of the flooding and erosion of North Core Banks during Hurricane Dorian was published.

Fieldwork was conducted in North Core Banks, North Carolina as part of rapid response to storms and recovery monitoring after Hurricane Florence (2018) and Dorian (2019). This work is supported by the Additional Supplemental Appropriations for the Disaster Relief Act of 2019 (Public Law 116–120, 113 Stat. 871).

By circulating water downward through a clear chamber (“capture cone”), bubbles of gas can be held, imaged and studied over time.  The left image shows bubbles of xenon in the process of developing coatings of gas hydrate.  The shiny bubble indicated near the top is hydrate-free, the white/opaque bubbles have coatings of xenon hydrate.  A few bubbles

The AIM group sent three members to Cape Hatteras National Seashore in North Carolina to train new U.S. National Park Service uncrewed aircraft system pilots in structure from motion best practices. The group was able to map the Bodie Island Lighthouse (pictured here) and a section of the beach at Ocracoke Inlet.

Detailed bathymetric maps of Buffalo Reef.  Improvements in grid resolution between the 2018 (left) and 2021 (right) surveys were facilitated by decreasing line spacing from 50 meters to 35 meters or less between adjacent lines.
