Greensea IQ Partners with WHOI to Advance Ocean Research Technologies
will tap into the combined strengths of Greensea IQ's advanced navigation, robotics, and remote operation systems alongside WHOI’s expertise in deep-sea exploration and underwater system design.Working closely with WHOI’s Deep Submergence Laboratory (DSL) and the National Deep Submergence Facility (NDSF), the initiative seeks to develop scalable technological solutions that enhance access to the deep ocean for scientific inquiry. By focusing on improving operational efficiency and ensuring compatibility with existing systems, the partnership aims to bolster the capabilities of

the first up-close investigation of the historic volcanic eruption and reveals several surprises. “Heading to the site, we were fully prepared to investigate a typical deep-sea explosive eruption,” said Adam Soule, WHOI associate scientist and chief scientist for the National Deep Submergence Facility. “When we looked at the detailed maps from the AUV, we saw all these bumps on the seafloor and I thought the vehicle’s sonar was acting up,” Soule said. “It turned out that each bump was a giant block of pumice, some of them the size of a van. I had

and friends.” “Sentry and the Observation Vehicle were designed for oceanographic research with funds from the National Science Foundation, but they’re also well-suited for the task of ocean search and recovery,” said Adam Soule, chief scientist for the National Deep Submergence Facility at WHOI. “These techniques have been honed during scientific expeditions over many years supported by federal agencies. This is a tremendous example of the unanticipated use of basic research that can be applied to help benefit society.” (Source: Woods

observation, computer modeling, technology development, and practical applications to real-world problems. WHOI brings together ocean experts with engineers to build innovative new technologies and tools necessary to advance ocean science. Since 1964, WHOI has operated the National Deep Submergence Facility, a federally-funded center that designs, builds and operates deep-sea exploration vehicles—Human Occupied Vehicle (HOV) Alvin, Remotely Operated Vehicle (ROV) Jason, Autonomous Underwater Vehicle (AUV) Sentry—for the benefit of the entire U.S. oceanographic community.

The autonomous underwater vehicle Sentry was developed with funding from the National Science Foundation and designed and built at WHOI. Managed by WHOI, the Sentry is operated through the National Deep Submergence Facility, a center funded by the National Science Foundation, the Office of Naval Research, and the National Oceanic and Atmospheric Administration and managed by WHOI. The NDSF operates, maintains, and coordinates the use of deep ocean research vehicles in coordination with the University National

The multidisciplinary group used their Woods Hole Oceanographic Institution’s Autonomous Underwater Vehicle (AUV) Sentry, operated as part of the National Deep Submergence Facility. Multibeam sonar and chemical and optical sensors were also used to hunt for the new hydrothermal oases on a track that explored a 600-km (400 mile) stretch of Pacific seafloor in the vicinity of the Marianas Trench Marine National Monument. This region, best known for including the
