dc.description.abstract | Climate-driven ice-water interactions in the contact zone between marine-terminating glaciers
and the ocean surface show a dynamic and complex nature. Tidewater glaciers lose volume through the
poorly understood process of calving. A detailed description of the mechanisms controlling the course of
calving is essential for the reliable estimation and prediction of mass loss from glaciers. Here we present the
potential of hydroacoustic methods to investigate different modes of ice detachments. High-frequency
underwater ambient noise recordings are combinedwith synchronized, high-resolution, time-lapse photography
of the Hans Glacier cliff in Hornsund Fjord, Spitsbergen, to identify three types of calving events: typical
subaerial, sliding subaerial, and submarine. A quantitative analysis of the data reveals a robust correlation
between ice impact energy and acoustic emission at frequencies below 200 Hz for subaerial calving. We
suggest that relatively inexpensive acoustic methods can be successfully used to provide quantitative
descriptions of the various calving types. | pl_PL |
