Over the past decade, the undersea robots known as autonomous underwater vehicles (AUVs) have become increasingly important in oceanographic research. Today's AUVs fall into two groups: 1) propeller-driven vehicles that can travel fast and carry lots of instruments, but are limited to expeditions of only a few days; and 2) "gliders," which can stay at sea for weeks or even months at a time, but cannot travel very quickly. MBARI engineers recently demonstrated a new super-efficient AUV that...

Researchers at the University of British Columbia are deploying an underwater robot to survey ice-covered ocean in Antarctica from October 17 through November 12. Scientists predict that the sea ice area around Antarctica will be reduced by more than 33 percent by 2100, accelerating the collapse of ice shelves. Up to hundreds of meters thick, ice shelves are floating platforms of ice that cover almost half of Antarctica's coastline. The mission will study the effect of ice shelves on the...

Autonomous underwater vehicle of the Alfred Wegener Institute dives under the Arctic ice for the first time The Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association for the first time sent its Autonomous Underwater Vehicle (AUV) on an under-ice mission at about 79° North. The four-metre-long, torpedo shaped underwater vehicle was deployed from the research icebreaker Polarstern under heavy pack ice. The vehicle was subsequently recovered by helicopter. "We...

Project to characterize subsurface oil plumes in the Gulf using latest technologies To characterize subsurface oil plumes in the Gulf using novel technology and the latest in biogeochemical techniques, a team of scientists from the Woods Hole Oceanographic Institution (WHOI) embarked on June 17 for a 12-day research effort in the Gulf of Mexico. Aboard the research vessel (R/V) Endeavor, they are conducting projects funded through the National Science Foundation (NSF)'s rapid response...

Tracking fish across Alaska's vast continental shelves can present a challenge to any scientist studying Alaska's seas. Researchers at the University of Alaska Fairbanks have successfully tested a possible solution in the form of underwater gliders. Last month, Peter Winsor, associate professor of physical oceanography, and Andrew Seitz, assistant professor of fisheries, tested the use of autonomous underwater vehicles, called gliders, for tracking tagged fish. Winsor and Seitz suspended...

MBARI's Division of Marine Operations, under an agreement with the National Oceanic and Atmospheric Administration (NOAA), sent a high-tech robotic submersible to the oily waters of the Gulf of Mexico. The goal is to collect information about the oil plume from the Deepwater Horizon drilling rig accident for NOAA. Although satellites and aircraft can help show the extent of the spill at the surface, MBARI's autonomous underwater vehicle (AUV) will help researchers understand the nature and...

NASA, U.S. Navy and university researchers have successfully demonstrated the first robotic underwater vehicle to be powered entirely by natural, renewable, ocean thermal energy. The Sounding Oceanographic Lagrangrian Observer Thermal RECharging (SOLO-TREC) autonomous underwater vehicle uses a novel thermal recharging engine powered by the natural temperature differences found at different ocean depths. Scalable for use on most robotic oceanographic vehicles, this technology breakthrough...

The Woods Hole Oceanographic Institution (WHOI) is part of an international sea search operation formed to locate the deep-sea wreck site of Air France Flight 447 and to retrieve the flight recorders from the Airbus A 330. Susan Avery, president and director of WHOI, said that the Institution "is honored to be part of this mission." A private, independent organization dedicated to marine research, engineering and higher education, "WHOI brings to the undersea search operation the necessary...

In a technological advance that its developers are likening to the cell phone and wireless Internet access, Woods Hole Oceanographic Institution (WHOI) scientists and engineers have devised an undersea optical communications system that"”complemented by acoustics"”enables a virtual revolution in high-speed undersea data collection and transmission. Along with the "transfer [of] real-time video from un-tethered [submerged] vehicles" up to support vessels on the surface, "this...
