Working at Palmer Station and along the Antarctic Peninsula aboard the research ship Polar Duke, two teams of marine biologists will measure how increased exposure to ultraviolet light may be affecting the antarctic marine ecosystem. The projects are part of the US study of the annual spring depletion of ozone over Antarctica and the effects of decreased ozone levels on the environment. Data show that staring 1979 a dramatic decrease in stratospheric ozone over the southern continent occurring each austral spring. In late August or early September, a hole about the size of the United States, begins to form; the decline continues through September and October, with a recovery during November. Scientists compared contemporary measurements of the total amount of ozone above Antarctica during October to amounts measured between 1950 and the 1970s. They found that the contemporary data showed that ozone abundance had decreased by as much as about 50 percent.
