Sea ice in the laboratory: understanding ice fracturing
A sea ice model allows researchers to observe in the laboratory how waves cause fracturing in the marginal areas of ice. Cameras, lasers, and wave generators help analyze the increasing fragility of sea ice in the face of seasonal melting.
In PMMH’s laboratory, scientists recreate sea ice with a floating layer of glue-based material. By generating controlled waves and recording deformations with a camera and laser, they measure the threshold at which ice fractures. This setup helps understand the dynamics of marginal ice zones and the increasing fragility of polar ice caused by seasonal melting.
