Abstract
Monitoring glacier dynamics across multiple timescales is essential for advancing our understanding of cryospheric responses to climate change. To address this challenge, the HERMIT project (High-Altitude and Polar Research through Integrated GNSS and Seismic Technology), supported by the Swiss Polar Institute, is developing a compact and affordable platform that integrates Global Navigation Satellite System (GNSS) and seismic sensors for deployment in high-altitude and polar environments. The HERMIT system combines millimeter-precision GNSS positioning with three-component seismic measurements in a modular package designed for harsh conditions. By relying on affordable yet highly performant components, HERMIT seeks to enable denser and more versatile monitoring networks, with applications ranging from glacier dynamics to paraglacial slope stability. This contribution presents the development of the platform and first results from a 2025 field campaign on the Rhone Glacier (Switzerland), where ten HERMIT stations were installed to examine the temporal and spatial interactions between basal sliding and subglacial hydrology during the melt season.
