Cruise Inventory Information
| Long name | RRS James Cook (740H) cruise JC149 Leg1 |
|---|---|
| Short name | JC149 Leg1 |
| Objectives and Narrative | The VOILA (Volatile recycling in the Lesser Antilles arc: Processes and consequences) research programme consisted of two cruises onboard RRS James Cook. Cruise JC149 forms the second leg. The cruise had two main aims: (1) to shoot into and collect 34 broad-band ocean bottom seismometers (BBOBS) sourced from Germany (DEPAS - 24 instruments) and USA (Scripps Institute of Oceanography - 10 instruments) deployed in March 2016 and (2) to conduct an active source seismic experiemnt with Short-period OBS sourced from the UK (OBIC - 25 instruments) and Germany (DEPAS - 24 instruments). Underway geophysical data (PES, MBES, SBP and gravity) were also collected along most transit between stations. Towed magnetic data were also collected along longer transits. One dredge was completed. A detailed swath survey of Kick'em Jenny volcano as requested by host-nation collaborators was also conducted. |
