Description/Abstract

This report describes the eleventh occupation of the Drake Passage section, established
during the World Ocean Circulation Experiment as repeat section SR1b. It was first occupied
by Southampton Oceanography Centre in collaboration with the British Antarctic Survey in
1993, and has been re-occupied most years. Thirty full depth stations were completed. The
CTD was a Sea-Bird 911plus with dual temperature and conductivity sensors, an altimeter, an
oxygen sensor, a transmissometer and a fluorometer. In addition, a SBE35 temperature
sensor and a downward looking RDI Workhorse WH300 ADCP (WH) unit were attached to
the CTD frame. On each station, the SBE35 collected data when the water sample bottles
were fired and a LADCP profile was logged. The underway measurements included
navigation, VM-ADCP, sea surface temperature and salinity, water depth and meteorological
parameters.
