Transport and variability of the Antarctic Circumpolar Current in Drake PassageRepeat hydrography on WOCE section SR1b from 1993 to 2000
Transport in neutral density layers




SAMW:Subantarctic Mode Water, AAIW:Antarctic Intermediate Water, UCDW/LCDW:Upper/Lower Circumpolar Deep Water, AABW:Antarctic Bottom Water

  • small transport variability in neutral density layers, particularly for the Circumpolar Deep Water
  • the variability in layers lighter than 27.0 kg/m3 is due to seasonal effects
  • 1996 the lowest transport year (123 Sv) has reduced transport in all density intervals
  • in other years with higher transports there does not seem to be a consistent pattern of transport anomalies
