Chlorofluorocarbon (CFC) and sulfur hexafluoride (SF6) were used to investigate the timescale of Antarctic Bottom Water (AABW) that spreads off Cape Darnley (CD) in East Antarctica.The age of the AABW was estimated based on the observed SF6/CFC-12 ratio while taking into account tracer dilution by L...
