RRS James Clark Ross, December 18, 2002–January 4, 2003. 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 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) and deployed along the track of TOPEX/POSEIDON satellites that collect altimter data from the area. During this cruise the BPR/IES were recovered and re-deployed in the Drake Passage. The Sea Level Recorders at Stanley, Rothera were serviced. The system at Rothera had a sensor replaced and the equipment at Stanley had an upgrade to allow transmission of date via email.
