Interstation Rayleigh and Love wave phase velocity dispersion measurements at periods of 8-25 seconds were extracted from seismic ambient noise cross-correlograms by automated frequency-time analysis (AFTAN). The ensemble of interstation Rayleigh wave dispersion measurements was used to develop 2D Rayleigh wave phase velocity maps of West Antarctica at periods of 8-25 seconds by Fast Marching Surface Tomography (FMST) on a grid with a node spacing of 0.75deg. 'Local' 1D Rayleigh wave phase velocity dispersion curves were extracted by sampling the 2D Rayleigh wave phase velocity maps at grid node locations. The local 1D Rayleigh wave phase velocity dispersion curves were inverted for 1D shear wave (Vsv) structure to 40 km depth, and the ensemble of 1D shear wave (Vsv) profiles were subsequently gridded to produce the 3D shear wave (Vsv) model of West Antarctica from 10-40 km depth.

Each station had a cold-rated Guralp CMG-3T 120 s seismometer sampling at 1 and 100 samples per second. The network was demobilised in austral summer 2017-2018. A detailed description of the data collection, quality control, processing and analysis is given in: O'Donnell, J. P. et al., 2019. Mapping crustal shear wave velocity structure and radial anisotropy beneath West Antarctica using seismic ambient noise. Data collection: The UKANET network used cold-rated Guralp CMG-3T 120 s seismometers sampling at 1 and 100 samples per second combined with Quanterra Q330 digitisers and B44 balers. Resolution: Lateral resolution is variable, depending on the seismic station locations. The 3D shear wave (Vsv) velocity model resolves lateral structure of wavelength 300 km with high fidelity in central West Antarctica. 
 Data quality: A detailed description of the data collection, quality control, processing and analysis is given in: O'Donnell, J. P. et al., 2019. Mapping crustal shear wave velocity structure and radial anisotropy beneath West Antarctica using seismic ambient noise. asNeeded completed
