On October 22, the Ocean Exploration Belief (OET) launched a 14-day expedition aboard exploration vessel Nautilus to survey among the most advanced deep-sea geology across the Major Hawaiian Islands. The primary goal of the expedition is to check a brand new widefield digicam array mounted on remotely operated automobiles (ROV). Footage from this method will then be used to create close to real-time thrilling functions for marine analysis and outreach. Excessive-resolution video and sonar information collected on this mission might be used to assemble three-dimensional fashions of every website utilizing rising instruments developed by the online game and film industries.
“This expedition is very distinctive as a result of we’re integrating new and thrilling digicam applied sciences to see the deep sea in methods we by no means imagined,” says Dr. Robert Ballard, NA156 Lead Scientist and OET Founder and President. “We hope to gather data and immersive imagery that may deliver the deep ocean to school rooms, computer systems, and minds worldwide.”
Operations utilizing Nautilus’ dual-body ROV system consisting of the primary ROV Hercules and the towsled Atalanta would be the most important focus of the expedition. Throughout every ROV seafloor survey, OET will accumulate high-resolution (<1 centimeter) visible and acoustic information over the seafloor utilizing a brand new widefield digicam array system and Norbit wideband multibeam sonar. The widefield digicam array was co-developed by the Ocean Exploration Belief and Sexton Company with funding from the Workplace of Naval Analysis (ONR). A custom-made software program bundle for the Norbit sonar was just lately developed by Corps of Exploration Navigator Dr. Kristopher Krasnosky, which takes uncooked information collected by sonar and permits onboard groups to visualise it in real-time.
Excessive-resolution visible and acoustic information collected by the ROV-mounted sensors might be used to develop high-fidelity georeferenced fashions of surveyed landscapes. Whereas related expertise has been utilized earlier than in deep ocean exploration, current advances in commercially accessible information processing instruments now considerably slim the time delay between information assortment and evaluation, thereby permitting fashions to be inbuilt close to real-time and help decision-making within the discipline. This expertise testing will proceed to advance the repertoire of exploration instruments accessible to scientists, in addition to discover potentialities for brand spanking new training & outreach experiences with the ocean.

“Whereas photogrammetry has been a device utilized in ocean exploration for many years, these mosaics took days or even weeks to supply. We intend to combine the best possible cameras with modern modeling software program to deliver mannequin creation to close real-time,” stated Jason Fahy, Expedition Chief.
This expertise might be examined and challenged by visualizing quite a lot of advanced underwater terrains all through the Hawaiian Archipelago, together with cliffs, pinnacles, and the lively submarine volcano Kamaʻehuakanaloa Seamount. The deep ocean surrounding Hawai’i has been studied for a really very long time, first by Polynesians who voyaged to this distant area over a thousand years in the past and later by many different researchers of various disciplines. Data acquired right here beforehand supplies a robust basis for utilized analysis, reminiscent of the brand new seafloor visualization instruments that might be developed throughout this expedition.
ROV dives might be operated in two completely different piloting schemes at every website. The primary mode will resemble OET’s typical exploratory dives, the place exploration targets are chosen and refined based mostly on seafloor sonar and visible information as it’s collected. The second mode might be a extra structured, linear, gridded dive plan designed to make sure steady protection of notable advanced terrain of curiosity.
“The Widefield Digital camera Array is a very cutting-edge immersive digicam system. We designed it to be a perfect device not just for the gathering of high-resolution imagery for three-dimensional photogrammetric fashions, but additionally hemispherical video for immersive dome projection, digital actuality, and IMAX-quality cinematographic productions,” stated Jonathan Fiely, OET Media Manufacturing Specialist and lead designer of the system. “We’re proud to have developed a digicam able to recording discoveries with the very best manufacturing high quality accessible for deep ocean exploration.”
Along with technical specialists, the expedition will embody at-sea participation of 4 college students and three classroom educators, who will acquire hands-on expertise with conducting scientific analysis within the discipline. As all the time the case with OET expeditions, group outreach is a key a part of this expedition’s targets. Audiences in Hawaiʻi and worldwide can be a part of the expedition workforce studying about these offshore underwater mountains through NautilusLive.org, which supplies 24-7 live-streaming, interactive occasions for colleges, deep-sea spotlight movies, and academic content material.
Utilizing the thrill of discovery, OET goals to create an ocean-literate society with workforce improvement, STEAM education schemes, and public outreach, specializing in participating traditionally marginalized teams. That is OET’s eighth expedition of 2023 and 156th within the 15-year historical past of this system, with the mission of exploring our ocean whereas pushing the boundaries of technological innovation, training, and outreach.
