Short summary
Receding tidewater glaciers are important contributors to sea level rise. Understanding their dynamics and developing models for their attrition has become a matter of global concern. Long-term monitoring of glacier frontal ablation is very difficult. Here we show for the first time that calving fluxes can be estimated from the underwater sounds made by icebergs impacting the sea surface. This development has important application to understanding the response of glaciers to warming oceans.
