Thirty-two full depth stations were completed, a test station, the RaTS station in Marguarite Bay, and the 30 stations for the SR1b Drake Passage section. The CTD was a Sea-Bird 911plus with dual temperature and conductivity sensors, an altimeter and an SBE35 thermometer.

Various underway measurements included navigation, VM-ADCP, sea surface temperature and salinity, water dept
