Ocean Exploration Trust's E/V Nautilus crew recently shared visuals it captured during its exploration of the USS Bugara.
This sunken submarine was used in World War II, the Korean War, and the Vietnam War before its 1970 retirement.
Located in the Olympic Coast National Marine Sanctuary, just off Washington, the vessel now serves as a habitat for various types of sea life.
Its sinking at that location was unintended.
The vessels exploration has a number of objectives, including mapping the wreckage, documenting the key structural components and assessing the variety of marine life that it hosts.
