Portal viewers can watch as it happens through the remote telepresence capability of Okeanos. NOAA will use the ROV on Okeanos Explorer to identify the targets and if they find it, to document the shipwreck. A mapping cruise earlier this year discovered several objects in the vicinity of where Hayate sank. The ship is currently conducting scientific baseline characterization of cultural and natural resources in the Wake Atoll unit of the monument. The search for the shipwreck is part a three-year campaign with NOAA Ship Okeanos Explorer, to explore the waters of the Pacific Remote Islands Marine National Monuments. Marine coastal defense guns, Hayate was the first ship sunk by American forces in the Pacific war. You can join live tonight, August 10 beginning around 5PM, on our Expedition Portal as NOAA Ocean Exploration and Research searches for the WWII Japanese destroyer Hayate, sunk at the Battle of Wake Island on Dec 11, 1941. From History of Japanese Destroyers, Kaigunsha Imperial Japanese Navy destroyer Hayate on trials, circa 1925. Daily dives can be followed on our Expedition Portal or on the Okeanos website. Okeanos will move on and will continue its current mission to conduct scientific baseline characterization of cultural and natural resources in the Wake Atoll unit of the monument, returning to Kwajalein on August 19. Since the ship was blown in half and sunk near an active region with high currents and a steep drop off, its wreckage may have been lost to the abyss. The team imaged two other possible targets that turned out to be huge rocks. The location of Hayate remains a mystery. Many interested members of the public watched from their home computers as undersea mysteries were revealed thousands of miles away and nearly a thousand meters deep. Scientists ashore were able to direct the ROV to image specific features through live hi-def video feeds and a teleconference link, while archaeologists and translators worked to research identifying markings in real time. Observers ashore were very impressed with the cool professionalism of the at-sea team, including ship crew, ROV operators, camera operators, and scientists, such as we have come to expect from prior dives. ROV Deep Discovery approaches bow of Amakasu Maru Twelve crewmen were lost in the sinking, but no evidence of remains was noted (or expected). Explorers were surprised to see significant remnants of wooden deck planking, surviving after nearly 74 years in the sea. The wreck was festooned with sea life and sprinkled with a light coating of sediment. Other features imaged as the ROV Deep Discoverer surveyed the wreck included deck guns, anchors, piping, masts, the pilot house and many other details. Viewers were able to clearly see evidence of torpedo damage on the stern. Three torpedoes fired by Triton hit the port side of Amakasu Maru and sealed her fate. All were sunk during the Pacific war by various causes. One of 26 built between 19, the ships were armed for anti-aircraft defense. 1 was an auxiliary water tanker, delivering precious fresh water to occupied islands such as Wake and to ships at sea. Kisogawa Maru, sistership of Amakasu Maru No. The identification was confirmed when Japanese characters welded on the stern were imaged and translated. With the aid of historian Tony Tully, explorers were able to verify that the vessel was in fact Amakasu Maru, a ship of almost identical size and with a similar bow configuration. But soon it became apparent that there were subtle differences between the wreck and details of Hayate. Explorers (including those watching live video via telepresence) were rewarded with stunning views of a shipwreck early in the dive. Earlier multi beam sonar surveys suggested a target of the right size and in the predicted location. Marine shore batteries during the Battle of Wake Island in December 1941. The team was aiming to locate the wreck of IJN Hayate, a Japanese destroyer sunk by U.S. 1, torpedoed and sunk by the submarine USS Triton (SS-201) on December 24, 1942. On August 11 the team imaged a World War Two Japanese armed tanker, IJN Amakasu Maru No. NOAA’s Okeanos Explorer and the ashore team made a historic discovery while exploring the Pacific Remote Islands Marine National Monument near Wake Island.
