Roger Andersen has participated in 45 polar field programs since joining the Polar Science Center in 1975, when it was the Arctic Ice Dynamics Joint Experiment (AIDJEX).

| Chipping a hole through old sea ice approximately 12 feet thick at Ice Station Fram 3 north of Greenland in late March 1981. “Hydroholes” like this allow scientists to lower instruments through the ice to make measurements of the ocean water underneath. Typically a warm building is assembled over the hole to keep it from freezing over and provide a warm work space. Six tons of ice chips were removed from this hole, and, yes, sea water is starting to gurgle through around the bottom. Thick multi-year floes like this have grown very rare in the Arctic over the past decade. |
