Abstract
In this active-source part of the VOILA (Volatiles in the Lesser Antilles) experiment, during James Cook cruise JC149 Leg 3, short-period ocean bottom seismometers (SPOBS) were deployed on the incoming plate and airguns from the James Cook vessel were fired to them. The OBS instruments were deployed in a roughly north-south orientation along strike, approximately 300-400km east of the trench and their positions were calculated by acoustic ranging. The data files presented here contain the vertical geophone components in standard SEG-Y format. Corrected airgun source-receiver distances have been added to the trace headers. The goal of this active-source portion of the VOILA experiment was to assess the geological structure and state of hydration of the subducting plate. The cruise report and other details may be accessed here https://www.bodc.ac.uk/resources/inventories/cruise_inventory/report/16390/. The chief scientist on Jame Cook cruise JC149 Leg 3 was Jenny Collier, and funding for the VOILA experiment was provided through a NERC multidisciplinary consortium project called Volatiles in the Lesser Antilles - VoiLA, supported by NERC award NE/K010743/1.
