Passive- and active-source seismic data recorded with Distributed Acoustic Sensing on Eastwind Glacier, Antarctica, February 2024

This dataset is a recording of passive seismic responses on Eastwind Glacier (Windless Bight, Ross Island, Antarctica), also containing 212 active-source seismic shots made with a hammer and plate source. The data are recorded using fibre optic distributed acoustic sensing (DAS), with a 2.2 km cable length connected into a FEBUS Optics A1 interrogator. The acquisitions take place over a two-hour period from 23:46 UTC on 2024-02-06, to 01:54 UTC on 2024-02-07. The acquisition is part of a broader campaign of seismic measurements to determine grounding line dynamics of Eastwind Glacier and image the bathymetry of the sub-shelf ocean cavity. The data were recorded as part of the ITGC TIME and EGGS ON TOAST projects, by a team from various UK and US institutions. The data are presented as HDF5 files. with supporting information provided in CSV files.
