About

G. McDonald is a pioneering figure in deep-sea and polar underwater robotics, whose work has fundamentally expanded humanity’s reach into the ocean’s most extreme environments. His primary research focuses on the design, development, and field deployment of hybrid underwater robotic vehicles capable of operating at hadal depths and under ice. McDonald’s most transformative contribution is his leadership on the *Nereus* hybrid remotely operated vehicle (HROV), a novel platform that could function as both a free-swimming autonomous vehicle and a tethered ROV. The landmark 2008 paper on *Nereus* (102 citations) details its successful sea trials, while subsequent field work in the Challenger Deep of the Mariana Trench (31 citations) proved the vehicle’s ability to perform scientific sampling at 10,903 meters—a feat that opened the hadal zone to routine exploration. Building on this success, McDonald led the design of *Nereid-UI* (28 citations), a specialized ROV engineered for under-ice oceanographic access in polar regions. His work has been instrumental in enabling scientists to study previously inaccessible environments, from the deepest ocean trenches to the ice-ocean interface of marginal ice zones, cementing his legacy as a key architect of modern deep-sea and polar exploration technology.
