Arnulf, Adrien, et al., (2018), Three-dimensional P-wave velocity structure of Axial volcano on the Juan de Fuca ridge (investigators: Adrien F. Arnulf, Alistair Harding, Graham Kent, William Wilcock). Interdisciplinary Earth Data Alliance (IEDA). doi:10.1594/IEDA/324420
Three-dimensional (3-D) P-wave velocity structure of Axial volcano obtained from joint travel-time tomographic inversion of downward extrapolated multichannel seismic data and ocean bottom seismometer (OBS) data. The data file is in ASCII format and contains 4 columns (x-local-coordinate, y-local-coordinate, z-local-coordinate, P-wave velocity). The local grid is centered on 45.91792N and -129.99305W and rotated 12.8749N. The included Matlab script can be used to plot the data set. Funding was provided by NSF grant OCE13-57076.
