Seismic velocity models (netCDF format) for the Lesser Antilles subduction zone (JC149, 2017)

These two-dimensional seismic P-wave and S-wave velocity models are derived from inversion of ocean bottom data collected in the western Atlantic, offshore the Lesser Antilles subduction zone during 2017 RRS James Cook cruise JC149. The velocity files are in GMT-compatible netCDF grid format with grid parameters as follows: The x-coordinate is profile distance in km (grid interval 0.075 km), the y-coordinate is depth in km below the sea surface (grid interval 0.01 km), and the z-values are P-wave or S-wave velocities in km/s. Also given is the Vp/Vs grid, with identical cell parameters, where the z-values are the Vp/Vs ratio. The data set was generated as part of the project called Volatiles in the Lesser Antilles (VoiLA), with funding from NERC award NE/K010743/1.
