    "description": "This metadata record presents observations of ice shelf anisotropy derived from borehole seismic data. Hot-water-drilled boreholes were created at two sites: Windless Bight (WB) near the grounding line on Ross Island and HWD-2 in the central Ross Ice Shelf. The boreholes housed seismometers frozen at various depths within the ice, enabling seismic observations of shear wave splitting (SWS) using active seismic sources.\n\nAt Windless Blight, borehole seismometers were installed at depths of 40 and 190 meters within the \u223C220\u2009m thick ice shelf during the 2016\/2017 Antarctic field season. Seismic shots were recorded with a 2,000\u2009Hz sampling rate and a 2\u2009s record length, triggered by striking plates. The site was revisited in December 2017 to validate sensor survivability and reproduce survey geometry for SWS analysis using multiazimuth shots.\n\nAt HWD-2, eight seismometers were deployed at depths ranging from 80 to 325 meters inside the \u223C370\u2009m thick ice shelf during the 2017\/2018 field season. A total of 747 shots at 53 different shot points were recorded, with clear observations of split shear waves in the data.\n\nThe study contributes valuable seismic data and methodology for understanding ice shelf anisotropy, enhancing our knowledge of Antarctic ice dynamics and seismic behavior.\n\nFurther details are provided at:\nLutz, F., Eccles, J., Prior, D.
