Potentials and Challenges of Cryoseismology with Fiber Optic Sensing in the High Arctic: A pilot experiment in Hornsund, Svalbard

Alfred Hanssen, Andreas K\"ohler, Andreas W\"ustefeld, Charlotte Bruland, Max Benke, Wojciech Gajek

Fiber-optic cables deployed across tundra and glacier in Svalbard can detect permafrost freezing, icequakes, calving, and river runoff.

✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We demonstrate how the dataset can be used for detecting permafrost freezing using noise interferometry, locating icequakes and calving events, as well as monitoring runoff from river-induced seismic noise.

C2weakest assumption

That the fiber-optic cable coupling to the ground or ice and the overall data quality remain sufficient under High Arctic conditions to produce usable signals from the targeted cryospheric processes.

C3one line summary

A multi-season DAS pilot in the High Arctic demonstrates feasibility for cryoseismological monitoring of permafrost, icequakes, and runoff while cataloging logistical and technical constraints.
