Remotely Operated Vehicles allow scientists to "go" where they never could before and open new realms for discovery in the Polar Regions. Iceberg investigators at the Monterey Bay Aquarium Research Institute (MBARI) used ROVs to sample ecosystems around these floating ice blocks.

Methane gas bubbling through seafloor sediments has created hundreds of low hills on the floor of the Arctic Ocean, according to researchers at the Monterey Bay Aquarium Research Institute (MBARI). These enigmatic features can grow up to 40 meters (130 feet) tall and several hundred meters across.

In Greek mythology, “Nereus" was a diety who could tell the future, but who would not answer questions unless he was caught. To avoid capture, he would change his shape. A new submersible explorer called Nereus also is very much in the business of shape-shifting; it can either be tethered to it operators as an "ROV" or operate independently an an "AUV", a combination that makes it ideal for Polar work. Its development by the Woods Hole Oceanographic Institution is supported by NSF, NOAA, and the U.S. Navy.

A robotic probe designed to draw a three-dimensional underwater map of an ice-bound Antarctic lake may prove an ideal tool to search for life on frozen planets or moons. A three-year, $2.3 million NASA project is building the probe--dubbed ENDURANCE (Environmentally Non-Disturbing Under-ice Robotic ANtarctiC Explorer)--that will map Antarctica's Lake Bonney, located in the McMurdo Dry Valleys.
