In February, Nicolas Mokus, Postdoctoral researcher working on WP2 at CNRS, joined partners from ISMER (Rimouski, QC, Canada), PMMH (Paris, France), and WHOI (Woods Hole, MA, USA) to instrument sea ice in the Saint Lawrence Estuary. The goal was to establish time series of the local sea ice state and properties and to compare an instruments and techniques. Using geophones and even smartphones as seismic sensors, they measured ice thickness and rigidity non-destructively. This year’s highlight: deploying optical fibres on the ice to track deformations with high spatial and temporal resolution. They also used drones extensively to capture imagery, enabling them to derive products like velocity fields.
