RRS James Clark Ross Cruise JR111, December 1, 2004 - December 22, 2004: ACCLAIM: sea level measurements in the Drake Passage

ACCLAIM Bottom Pressure Recorders have been used for making measurements of the Antarctic Circumpolar Current (ACC) since 1988, initially in the Scotia Sea and then later across the Drake Passage between the Falkland Islands and the Antarctic peninsula. Some of the Bottom Pressure Recorders (BPRs) are combined with Inverted Echo Sounders (IES). During this cruise the one BPR and one BPR/IES were recovered and re-deployed in the Drake Passage. In addition to this, a third BPR was deployed in between the two existing recording sites. The Sea Level Recorder at Stanley was serviced.
