SEIS-ADELICE temporary experiment measuring the cryo-seismicity of the Astrolabe glacier in Terre Adelie, Antarctica (RESIF-SISMOB)

To analyze the dynamics of Antarctica coastal glaciers and their interaction with the ocean, SEIS-ADELICE aims at measuring the cryo-seismicity of the Astrolabe glacier (Terre Adélie, Antarctica) from land and ocean bottom seismic observations. The first instrumental deployments occurred in January and February 2022. They consisted in a network of 6 broad-band (BB) stations from the French INSU-SISMOB pool deployed on the grounding line of the Astrolabe glacier, together with 4 OBS deployed at sea few km off the floating tongue of the glacier. These stations were complemented by semi-permanent BB seismological stations deployed on stable ice around the glacier for long term (several years) recording of the ice and of the glacier cryogenic activity.
