Shear wave splitting catalogue, Rutford Ice Stream (West Antarctica), November 2018 to February 2019
This dataset contains an ASCII file with shear wave splitting results for 202,651 station-event pairs from glacial micro-seismicity, recorded from a 35-station seismic network located ~40 km upstream of the grounding line of Rutford Ice Stream, West Antarctica. Microseismicity is located at the base of the ice stream at ~2.2 km depth (relative to the ice surface). Seismic waveform data, which was used to calculate shear wave splitting parameters is provided in miniseed format. Event hypocenter information, event times and coordinates of receiving stations are listed in the ASCII file. Shear wave splitting was calculated using the software MFAST. Shear wave splitting parameters can be used to determine seismic anisotropy along the ray path, which helps to characterise ice fabric.
This work was funded within the BEAMISH project by NERC AFI award numbers NE/G014159/1 and NE/G013187/1. Seismic instruments were provided by NERC SEIS-UK (Loan 1017) and the Incorporated Research Institutions for Seismology (IRIS) through the PASSCAL Instrument Center at New Mexico Tech.
