Antarctic climate research. Japanese scientist taking measurements from an ice core in Antarctica, to gain information about changes in atmospheric conditions. The core is a tubular sample taken by drilling into the Antarctic ice sheet, formed by snow which fell on Antarctica over thousands of years. Data obtained from the core will provide evidence of past changes in the Earth's climate and of current trends in atmospheric pollution. Photographed on the Filchner Ice Shelf, Weddell Sea, Antarctica.
