Tony Hansen of the Engineering Division, an expert in atmospheric research, is returning to the Amundsen-Scott South Pole station to continue his pollution studies, which are funded by the National Science Foundation. As he did last year, Hansen will be posting regular updates from the South Pole on his interactive website (http://www.mageesci. com/Antarctic). This time, he hopes to add 10-to-15-second digitized video clips to the site. Hansen's research focuses on the effects of exhaust fumes on people unloading cargo planes in the rarefied atmosphere of the South Pole--particularly on women of child-bearing age. "This is the equivalent of sticking your head in the exhaust pipe of a school bus as 12,000 ft altitude," said Hansen, who hopes to a devise a means to minimize the amount of pollution to workers at the Pole. Hansen will be at the South Pole until Feb. 10, and can be reached there by e-mail at [email protected]. (ZBD9801-00122.jpeg)
