Abstract
- This report describes the 16th occupation of the Drake Passage CTD section, established duringthe World Ocean Circulation Experiment as repeat section SR1b. It was first occupied byNational Oceanography Centre (previously IOSDL and then SOC) in collaboration with theBritish Antarctic Survey in 1993, and has been re-occupied most years since then. Thirty onefull depth stations were performed during JR195: two test stations, and 29 of the 30 nominalstations for the SR1b Drake Passage section. Two 500 m stations were added as part of POL'scruise JR198.The CTD was an underwater SBE 9 plus unit equipped with the following sensors: dualtemperature and conductivity sensors, a pressure sensor encased in the SBE underwater unit, aSBE-43 oxygen probe, an Aquatracka MKIII fluorometer, a transmissometer, an upwardlookingdownwelling PAR sensor, and an altimeter. A downward-looking LADCP (RDIWorkhorse Monitor 300 kHz) was deployed on all stations, except for the two 500 m stationswhen it was replaced by a 600 kHz LADCP from Bangor University.Various underway measurements were obtained, including navigation, VM-ADCP, sea surfacetemperature and salinity, water depth and various meteorological parameters.
