Mid-Cayman Spreading Centre Hydrothermal Vents located by Cruise RRS James Cook 44, Mar-Apr 2010

The cruise (JC44) started with a high resolution multibeam survey (Simrad EM120 bathymetry with 50m resolution) and TOBI survey (30kHz deep-towed sidescan sonar with 3m resolution) of the entire Mid-Cayman Rise. We followed this with a plume survey using CTD casts and fine scale mapping using the new AUV, Autosub 6000. The target areas were initially based on the earlier RV Cape Hatteras plume data but were quickly modified following the results from our new surveys.
