RRS 'James Clark Ross' Voyage 1, 20 December 1991 - 10 January 1992. ACCLAIM: sea level measurements in the Scotia Sea and Drake Passage

ACCLAIM Bottom Pressure Recorders have been in place in the Scotia Sea since December 1988 and recovered/redeployed in 1989 and 1990. On this cruise the BPRs were complemented by two combined BPR/INVERTED ECHO SOUNDER rigs deployed in the Drake Passage. The principle aim of the excercise is to study the variations in flow of the Antarctic Circumpolar current on large time space scales. In addition remote island Sea Level Recording stations at Port Stanley-Falkland Islands, Signy Island-South Orkneys, and Faraday were upgraded. No problems were encountered during the cruise operations, weather conditions were excellent for this area and data return from the recovered instruments was 100%
