Between September 8 to 12, 2023, a journey into the past took place in the waters within Papahānaumokuākea Marine National Monument (PMNM). The Ocean Exploration Trust’s E/V Nautilus embarked on an expedition to re-explore three iconic World War II aircraft carriers lost during the Battle of Midway.
For the first time since its sinking, eyes set upon the Imperial Japanese Navy (IJN) Akagi. The expedition also provided a fresh look at the USS Yorktown, which hadn’t been visually assessed since its discovery a quarter of a century ago. Additionally, a thorough survey of the IJN Kaga was conducted.
Dr. Daniel Wagner, Chief Scientist for Ocean Exploration Trust, expressed the expedition’s significance, highlighting over 43 hours spent surveying these iconic vessels. Observations like anti-aircraft guns still aiming skywards painted a vivid picture of their last moments.
Rick Spinrad, Ph.D., NOAA Administrator, recognized the expedition as a solemn privilege. He emphasized the importance of the collaborative effort and the opportunity it provided to share these discoveries with the world. The mission’s live video streams made it possible for a global audience to join this deep-sea exploration, honoring the historical event.
The significance of this collaborative effort was echoed by Kosei Nomura of the Embassy of Japan. He remarked on the shift from former adversaries to current allies, now united in exploration and appreciation of history.
The expedition explored IJN Akagi for 14 hours, offering insights into its battle scars and the aftermath of its tragic end. Samuel Cox, Director of the Naval History and Heritage Command, underscored the value of such collaborative endeavors. He emphasized the importance of preserving the final resting places of sailors, both American and Japanese.
A notable highlight was the survey of USS Yorktown, which the world viewed in real-time. Its initial discovery 25 years ago was the fruit of a collaboration between the U.S. Navy and the National Geographic Society. This recent venture added to that legacy, offering a detailed archaeological survey of Kaga, sharing invaluable data with the public.
PMNM, a UNESCO World Heritage site, holds a dual distinction for its cultural and natural importance. Efforts are underway to grant it national marine sanctuary status, ensuring its treasures are protected for future generations.
This exploration, part of the E/V Nautilus Ala ʻAumoana Kai Uli expedition, is a testament to the collective effort of various institutions. From NOAA to academic institutions in Japan and the U.S., it was a harmonious confluence of expertise, determination, and reverence for history.
