USGS Coastal Landscape Change Products Help the U.S. Department of Defense Safeguard Military Infrastructure Along the Coast USGS Coastal Landscape Change Products Help the U.S. Department of Defense Safeguard Military Infrastructure Along the Coast
The U.S. Department of Defense is supporting the geographic expansion of the USGS Coastal Change Likelihood and Coastal Landscape Response assessments. These assessments are critical to understanding future coastal landscape change that could impact military installations, sites, and infrastructure along the U.S. Atlantic and Gulf Coasts.

We Make Treasure Maps: USGS Charts the Seafloor to Help Locate Critical Minerals, Precious Metals, and Other Vital Resources We Make Treasure Maps: USGS Charts the Seafloor to Help Locate Critical Minerals, Precious Metals, and Other Vital Resources
USGS marks the spot! Our science is key to understanding seabed resources. Our maps characterizing the seafloor can help find critical minerals and other resources in high demand worldwide. While advancing scientific knowledge of the seafloor, USGS also leads a national effort to locate the critical minerals needed to drive the U.S. economy and national security. Some of the answer is under water.

What are Key Conditions for Marsh Survival Amid Rising Seas? What are Key Conditions for Marsh Survival Amid Rising Seas?
As sea levels continue to rise, coastal marshes face increasing risk of inundation and erosion. These wetlands rely on a steady supply of sediment to keep up with rising waters, but the suite of conditions that control sediment accumulation are difficult to predict.

Awards
USGS Unit Award for Excellence of Service
The Extended Continental Shelf team was awarded the USGS Unit Award for Excellence of Service, an award that recognizes groups of employees who have worked together as a unit to achieve exceptional results. This team was part of a Federal interagency effort to identify the outer limits of the U.S. extended continental shelf (ECS)—the area beyond 200 nautical miles from shore where the U.S. can manage marine resources. The U.S. ECS outer limits were publicly announced in December 2023 for the first time in history.

Fieldwork
Long Island Sound SEABOSS Survey
A seafloor mapping survey in Long Island Sound took place in May with collaborators from the University of Connecticut and the University of New Haven. They are mapping the area’s geology and biota to identify seasonal changes from their previous survey in November 2024. The USGS is mainly involved with seabed classification and characterizing the geologic framework of the region using bathymetry, backscatter, seismic reflection, and sediment samples, videos, and photos.
Long Pond Mapping
At the request of the Town of Falmouth in Massachusetts, we mapped Long Pond using shallow water multibeam sonar and a chirp sub-bottom sonar in April. In addition, the Aerial Imaging and Mapping Group conducted a drone/lidar survey.
Outreach and Other Activities
WFSU Documentary on Research Cruise
WFSU produced a documentary covering a research cruise offshore Oregon to Astoria Canyon (2023) and smaller campaigns to the Hydrate Ridge seep system (2024) to study the cycling dynamics of dissolved organic matter at methane seeps. Understanding how much natural gas may be available to extraction requires a careful understanding of the transport and fate of methane near the seafloor of methane seeps. John Pohlman (research chemist) was one of the Principal Investigators for the study, both he and Ellen Lalk (research chemist) represented USGS on the research cruise.
The 26-minute video is available for streaming on both YouTube and the PBS app through their station. Read the blog and watch the documentary.
Marine Geohazards Presentation at Woods Hole Oceanographic Institution
Uri ten Brink (research geophysicist) gave a presentation, titled "Constructing virtual geological outcrops of the deep sea from legacy ROV videos: Method and examples," during the Woods Hole Oceanographic Institution Geology and Geophysics Department Seminar Series in May. The 48-minute presentation is available for viewing on the Woods Hole Oceanographic Institution website.
Bathymetry Panel Discussion
Jason Chaytor (research geologist) was invited to participate in a panel discussion on proposed new activities of the National Academies Ocean Studies Board during the Spring 2025 meeting. The topic was bathymetry data, covering questions relating to the purpose for collecting and using bathymetry data, resolutions and scales, curation and accessibility, cyber-infrastructure needs, and AI/Machine Learning. This is the first step in developing a new National Academies study or workshop. Mapping seafloor topography provides fundamental information needed for offshore resource identification, hazard preparedness, marine navigation, and more. USGS visibility at this meeting is critical for reinforcing our role in this work nationwide.
USGS Long Island Sound Webinar
The USGS hosted a webinar highlighting new USGS tools developed for use in Long Island Sound. Rachel Henderson (physical scientist) gave a presentation titled, "Long Island Sound near-term coastal change application." It focused on shoreline change assessments, highlighting the Coastal Change Likelihood assessment, Coastal Landscape Response assessment, and the Digital Shoreline Analysis System (DSAS).
Presentations at Gulf of Maine Symposium
Laura Brothers (marine geologist) and Neil Ganju (research oceanographer) presented at the Gulf of Maine Symposium in Haverhill, Massachusetts in April, where more than 150 monitoring program coordinators and researchers, data users, and policymakers gathered to learn about ongoing research in the Gulf of Maine. Laura’s talk was about seafloor mapping and its implications for benthic habitat and development; Neil’s talk was about geospatial analysis to support salt marsh management and restoration. A panel discussion followed each of their sessions.
Local Geology Talk
In March, Jin-Si Over (geographer) gave a geology talk at Jonathan Bourne Public Library in Bourne, Massachusetts to about 40 people. Days later, there was a follow-up walk to identify rocks and minerals at Little Island Trust in Falmouth, Massachusetts with about 20 people.
"Secrets of the Seep is about the work that goes into researching the ocean bottom. Scientists spend years planning for those precious few days they have at sea. How can they overcome the challenges of an uncooperative environment to answer their scientific questions?"
