Reflections on Spending a Winter at the South Pole:
"It Was a Dark and Stormy Night" – for Six Months!

6/25/2007 Right now, it's the middle of winter at the South Pole. Read the personal takes of two NOAA researchers on what it's like to conduct cutting-edge science while cut off from the rest of the world at NSF's Amundsen-Scott South Pole Station. More

Student-designed Underwater Vehicles Square Off in an International Competition with an IPY Emphasis

6/23/2007 In recognition of IPY, the 2007 MATE international Remotely Operated Vehicle (ROV) competition challenged students to design and build ROVs capable of operating in the polar environments. More

Antarctic Icebergs: Unlikely Oases for Ocean Life

6/21/2007 Icebergs have long gripped the popular imagination, but now scientists have discovered that these floating ice islands have a major impact on the ecology of the ocean around them. More

Hybrid Explorer Will Have the Flexibility to Operate in the Harshest Environments

6/18/2007 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. More

Scientists use Remotely Operated Vehicle to Dive Underneath Antarctic Icebergs

6/18/2007 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. More

Methane Bubbling through Seafloor of the Arctic Ocean Creates Undersea Hills

6/18/2007 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. More

Study of Glacial Retreat Shows that Much of the World Emerged from Last Ice Age at Nearly the Same Time

6/8/2007 A climate science puzzle has been why different parts of the world, notably Greenland, seemed to warm at different times at the end of the Ice Age. A new study sheds light on warming 17,500 years ago. More
