The ocean floor holds more than just mystery. It could hold the keys to America’s energy future. That’s why we are making big moves to better understand the hidden mineral resources of the U.S. Outer Continental Shelf (OCS).
The Bureau of Ocean Energy Management (BOEM) manages the development of OCS energy, mineral, and geological resources in an environmentally and economically responsible way. To support this mission, we are prioritizing important offshore areas likely containing critical minerals, which need detailed mapping and exploration to ensure environmental safety and protect historic sites.
Research Takes Teamwork
From June 15 to July 2, 2025, BOEM joined an elite crew of ocean explorers aboard the R/V Atlantis to investigate one of the least-known stretches of U.S. waters: the Aleutian Arc. This epic expedition, led by the U.S. Geological Survey (USGS), brought together federal scientists, academic experts, and partners from the National Oceanic and Atmospheric Administration (NOAA) to gather vital data on critical marine minerals and deep-sea ecosystems. BOEM’s own Dr. Christina Bonsell and Dr. Shannon Cofield were on deck, lending their expertise and curiosity to the mission.
What We Found (Spoiler: It's Cool)
This journey built on previous discoveries from Saildrone mapping missions that uncovered previously unknown seamounts and signs of hydrothermal activity. The team dove even deeper this time—literally—with the U.S. Navy’s Human Occupied Vehicle (HOV) Alvin, collecting stunning imagery and seafloor samples thousands of meters below the surface. The findings will help us understand where critical minerals like cobalt and rare earth elements might be found, and what kinds of deep-sea life are thriving alongside them.
Cutting-Edge Tech & Real-World Impact
Across 21 days, researchers used state-of-the-art sonar, cameras, and sampling tools to explore undersea landscapes that have rarely—if ever—been seen by human eyes. This mission is part of a larger effort called Seamount Benthic Mapping and Characterization, aimed at identifying new hydrothermal vents, mineral-rich zones, and the unique creatures that call them home.
Why It Matters
Critical minerals are essential to everything from smartphones to clean energy tech. But before any decisions are made about accessing these resources, we need to understand where they are—and how to protect the environment around them. That’s why BOEM is leading research that balances exploration with stewardship.
This work also supports President Trump’s Executive Order 14285 to “Unleash America’s Offshore Critical Minerals and Resources,” strengthening domestic supply chains and national security.
