Scientific paper

A series of developments in ocean science and technology resulting from a unique confluence of opportunity have resulted in important advances leading to improved operational capabilities, impacting exploration and discovery of new environments within the Earth’s Oceans. The ASTEP funded Oases project to the Mid Cayman Rise, when teamed with other complimentary developments and field programs, represents an important example of how oceanographic robotic systems and the scientific techniques they utilize can make important impacts not only improving state of the art for ocean exploration and discovery but also revealing how such advanced systems and techniques may impact exploration of other planets. The recent NSF-funded Nereus vehicle development, resulting in a novel system able to explore the deepest reaches of the ocean to 11,000 meters depth, has been utilized within the OASES project to help advance exploration capabilities through the use of new concepts in how robots interact with their human operators when confronted with the reality of a restricted communications environment -typical in the deep oceans of this planet. Likewise, other field programs funded outside NASA utilizing the autonomous vehicle Sentry complement these experiences. Indeed, the extreme nature of Nereus’ mission of exploring the deepest regions of the ocean leads to new opportunities to perform new scientific missions within oceans subject to ice cover. During the OASES cruise, Nereus demonstrated several of the technological aspects required to work in an ice-covered ocean while also illuminating many of the challenges associated with real-time control and decision making needed to achieve a fully capable system able to explore and sample new environments undersea.
