PurposeResearch
ObjectivesThe VOILA (Volatile recycling in the Lesser Antilles arc: Processes and consequences) research programme will consist of two cruises onboard RRS James Cook. Cruise JC133 forms the first leg. The main aim of the cruise (SME 698) was to deploy 34 broad-band ocean bottom seismometers (BBOBS) sourced from Germany (DEPAS – 24 instruments) and USA (Scripps Institute of Oceanography – 10 instruments). Underway geophysical data (PES, MBES, SBP and gravity) were collected along most transit between stations. Towed magnetic data were also collected along longer transits together with three short dedicated magnetic surveys designed to infill at critical locations (between stations 5&6; 21&22 and 33&34) and give rest periods for the BBOBS teams. A detailed swath survey of Kick'em Jenny volcano as requested by host-nation collaborators was also conducted and provided a further rest break for BBOBS personnel. Despite sailing 36 hours late, vessel operations at sea were excellent and there was no subsequent science time lost. As a consequence all scientific work was successfully completed in 9 days between 8 -16 March 2016, starting in Port of Spain, Trinidad and ending in St John's, Antigua. The seabed instruments will be collected during the second leg in May 2017 (SME 697), when an active source OBS experiment will also be conducted.
