Woods Hole Oceanographic Institution (WHOI) engineers and scientists are employing a combination of new undersea technologies to re-define how we think of tethered, remotely operated vehicles. Using the 11,000 meter-rated Nereus hybrid remotely operated vehicle (HROV) as a test platform, engineers at WHOI recently demonstrated a new system that integrates acoustics with optics. This achievement, they say, opens the way to new opportunities in communications between untethered remotely operated vehicles (UTROVs) and their human operators—literally “cutting the cord” for undersea exploration.
ABE, a pioneering deep-sea exploration robot—one of the first successful submersible vehicles that was both unmanned and untethered to surface ships—was lost at sea Friday, March 5, on a research expedition off the coast of Chile.
Oceanographers using the remotely operated vehicle (ROV) Jason discovered and recorded the first video and still images of a deep-sea volcano actively erupting molten lava on the seafloor.
A new type of deep-sea robotic vehicle called Nereus has successfully reached the deepest part of the world’s ocean, reports a team of U.S. engineers and scientists aboard the research vessel Kilo Moana. The dive to 10,902 meters (6.8 miles) occurred on May 31, 2009, at the Challenger Deep in the Mariana Trench in the western Pacific Ocean.
The Woods Hole Oceanographic Institution (WHOI) has partnered with the Waitt Institute for Discovery to make deep-sea exploration technology and a world-class operations group broadly available for the oceanographic community.
Scientists and engineers from WHOI and the University of Washington have successfully completed the first scientific mission with Sentry, a newly developed robot capable of diving as deep as 5,000 meters into the ocean. The vehicle surveyed and helped pinpoint several proposed deep-water sites for seafloor instruments that will be deployed in the Ocean Observatories Initiative.
Bone-chilling temperatures, biting winds, and rapidly changing sea ice conditions make the Chukchi Sea off Point Barrow, Alaska, a particularly challenging place to work. And then there are the curious neighbors - towering polar bears that periodically stop by camp unannounced.
Taking a page out of a science fiction story, researchers from the Woods Hole Oceanographic Institution (WHOI) and Webb Research Corporation (Falmouth, Mass.) have successfully flown the first environmentally powered robotic vehicle through the ocean. The new robotic “glider” harvests heat energy from the ocean to propel itself across thousands of kilometers of water.
Lockheed Martin Successfully Completes Preliminary Design Review for New Scientific Research Mini-Sub
Lockheed Martin recently completed a Preliminary Design Review for the Replacement Human Occupied Vehicle (RHOV), a next generation three-person Deep Submergence Vehicle that will be used by the U.S. scientific community.
In the summer of 2007, engineers from WHOI’s Deep Submergence Laboratory proved they could operate an autonomous underwater vehicle (AUV) beneath Arctic ice.
WHOI Awards Lockheed Martin $2.8 Million Contract to Design Submersible Replacement Human Occupied Vehicle
WHOI has awarded Lockheed Martin a $2.8 million contract for the initial design of the Replacement Human Occupied Vehicle (RHOV), a next generation three-person Deep Submergence Vehicle (DSV) that will be used by the U.S. scientific community. The contract has an option for subsequent construction of the RHOV once the initial design is completed and the project is approved to move forward.
Researchers will probe the Gakkel Ridge during expedition that begins on July 1.
A lot of ocean science equipment goes into the water and never comes back. Some of it was intended to stay; other times, the sea claims it by force.
Listen to the first call between ocean explorers and astronauts.
The Autonomous Benthic Explorer, ABE, one of the first autonomous underwater vehicles (AUVs) to routinely work in the deep ocean, has joined the U.S. National Deep Submergence Facility, providing ocean scientists with a full range of tools to explore the deep sea.
Scientists will explore the seafloor near
Papua New Guinea in the western Pacific Ocean later this month, investigating
hydrothermal vents and the formation of mineral deposits containing
gold and other precious minerals with industrial value.
Dramatic new video of a long-term volcanic eruption in the western Pacific first discovered in 2004 has been captured during a recent cruise by the remotely operated vehicle JASON, developed and operated by WHOI’s Deep Submergence Laboratory.
Marine scientists and engineers will brief investors, business development executives, commercialization partners and economic development leaders May 24 at a conference at WHOI aimed at showcasing marine technologies and concepts ready for commercialization or licensing.
WHOI biologists and physical oceanographers joined forces in May to study the effect of ocean currents on fish larvae spawned on coral reefs in Belize.
The Deep Submergence Vehicle (DSV) Alvin finished a five-month overhaul in Woods Hole in early April and returned to sea April 19 aboard support vessel Atlantis for what may be Alvin's last voyage.
