Bathymetric data of volcano-like feature discovered by science teams aboard the U.S. Coast Guard Cutter Healy (WAGB 20) on the continental slope along Northern Alaska during the Healy's Phase 1 Arctic 2024 Fall Deployment supporting Alaskan Arctic Coast Port Access Routing Study and Opportunistic Mapping Initiative. The feature discovered rises from the seabed approximately 585 meters, residing approximately 1,600 meters below the surface at its shallowest depth. The interagency science mission to the Chukchi and Beaufort Seas north of Alaska combined oceanographic buoy deployments with a coordinated mapping effort to survey uncharted waters and acquire depth data along a portion of the Alaskan Arctic Coast Port Access Route Study (AACPARS) corridor, a Coast Guard-proposed preferred vessel route from Utqiaġvik, Alaska, to the demarcation point of the border between U.S. and Canada.
