NOAA’s deepwater exploration of the Mariana Trench with the Okeanos Explorer, a former Navy surveillance vessel, has wrapped up with some wild and weird new discoveries. Many new species never seen before as well as the discovery of a WWII B29 bomber wreck on the seafloor. The Mariana Trench contains the deepest spot in the ocean at 36,037 feet and is located in the Pacific Ocean off the Mariana Islands.

“After a successful third leg, the 2016 Deepwater Exploration of the Marianas Expedition is complete! We’ve had a fantastic cruise with 22 dives with an abundance of discoveries that included new hydrothermal vents, the first ever petite spot volcano in US waters, a new mud volcano, several areas of high density deep sea corals and sponges, as well as dozens of new species and new records. Yesterday’s discovery of the WWII B29 Bomber was just icing on the cake. NOAA Ship Okeanos Explorer has returned to Guam and our team will spend the next couple days wrapping up cruise products and prepping for the next mission.”
