A glaciologist in Antarctica digs a snow pit prior to taking snow & ice samples for the analysis of trace metals. The glaciologist, a member of the British Antarctic Survey (BAS), is dressed in surgical garments to minimise contamination of the samples. Analysis of Antarctic snow & ice samples is important in the study of past & current trends in the pollution of the atmosphere.
