Cryoseismic activity and dynamics of the Astrolabe Coastal Glacier, East Antarctica - The SEIS-ADELICE project (2020-2025)

As part of the SEIS-ADELICE project (2020–2025), hundreds of seismological instruments were deployed on and around the Astrolabe Glacier in Terre Adélie, East Antarctica. The aim was to monitor the cryoseismic activity of an Antarctic outlet glacier as it reaches the ocean, image its internal structure and thickness, and investigate its interactions with the underlying ocean and local bedrock. This paper describes the sequential deployment of broadband, mid-band, and short-period instruments on land and at sea, the noise levels obtained in various environments and the quality of the seismological data in different frequency bands. It also presents a few non-exhaustive examples of data to demonstrate their quality and potential for analysing various cryoseismic sources at different times, frequencies, and geographic scales.
