PurposeResearch
ObjectivesThe main objectives for the JR67 were:
i. To determine the interannual variability of the position, structure and transport of the Antarctic Circumpolar Current (ACC) in Drake Passage;
ii. To examine the fronts associated with the ACC, and to determine their positions and strengths;
iii. By comparing geostrophic velocities with those measured directly (by the lowered ADCP), to determine the size of ageostrophic motions, and to attempt to estimate the barotropic components;
iv. To examine the temperature and salinity structure of the water flowing through Drake Passage, and to identify thereby the significant water masses;
v. To calculate the total flux of water through Drake Passage by combining all available measurements.
Other work was also undertaken on this cruise and involved swath bathymetry of the Shackleton Fracture Zone (PSO Roy Livermore JR69)
