On Dec. 7, the 75th anniversary of the attack on Pearl Harbor, the National Oceanic and Atmospheric Administration ship Okeanos Explorer explored a Japanese mini-submarine, using an ROV. The sub is 5 miles off the entrance to Pearl Harbor and was sunk by the USS Ward on the morning of Dec. 7, 1941, 90 minutes before the Japanese bombed Pearl Harbor by air.

NOAA is preparing for the third year of its “Campaign to Address Pacific Monument Science, Technology and Ocean Needs” — a project to collect scientific data in U.S. marine protected areas in the central and western Pacific and was on one of two shakedown cruises when they filmed the historic Japanese sub wreckage.
The team is testing its mapping, remotely operated vehicle (ROV) and telepresence system capabilities.
