PUNTA ARENAS, Chile — In a perfect world, IceBridge researchers would make science flights over Antarctica almost every day and return home with a check next to every high-priority science flight. The 2009 campaign — the first year IceBridge made flights over Antarctica — was just about perfect. But that’s a rarity in Antarctic research where whether and unanticipated aircraft maintenance can ground flights.

During days on the ground, however, researchers keep busy. On Monday, Nov. 15, IceBridge scientists gathered at Universidad de Magallanes in Punta Arenas, Chile, to answer questions from local reporters and from reporters in Santiago via live video feed (video below).

Sea Ice in HD

From: Michelle Williams, video producer, NASA’s Goddard Space Flight Center

Flying in a four-engine jet at 1500 feet above Arctic sea ice for eight hours sounded a little nerve-racking before I left for Thule, Greenland with Operation IceBridge. I am tagging along as a video producer for the first two weeks of the mission, and it has been a fascinating experience so far.

We landed in Thule on Monday, March 22, after an overnight transit flight from Palmdale, California. As we approached the airstrip, the pilots kindly invited me to film the landing from the cockpit.

Our science flight on Tuesday, March 23, was a sea ice flight near Canada’s Ellesmere Island. We flew at an altitude of about 20,000 feet for an hour and then descended to between 600-1500 feet for the remainder of the flight over the frozen surface of the Arctic Ocean.

NASA’s 40-year old DC-8 is a workhorse, and it is surprisingly steady at such a low altitude. The plane was not originally designed for low-altitude flying, but it performs well in this environment. Pilots Dick Ewers and Bill Brockett have over 80 years of experience between the two of them, and with the help of navigator Manny Antimisiaris and flight engineer Doug Baker they expertly maneuver the plane over the ice.

The glacier flight on Wednesday, March 24, was just as spectacular. We flew a grid pattern over the upper and lower segments of the Petermann Glacier, winding along the river of ice to sea level and back to the interior of the island.

The footage I’ve collected so far will be used for a number of IceBridge videos when I return to NASA’s Goddard Space Flight Center in April. Keep an eye on the IceBridge site and the multimedia gallery.
