Predictions of future sea level rise depend on accurate estimates of the rate at which ice sheets deliver fresh water and ice to the oceans. These estimates are provided by models, which, in turn, depend on our understanding of iceberg calving, among other processes. Due to a lack of observations, the ability to project rates of iceberg calving needs improvement. This project works towards providing an inexpensive means of detecting and, potentially, characterizing such events, using the underwater noise generated by calving events. The data of this archive is limited to the set of underwater acoustic measurements collected in Sarqardleq fjord in West Greenland during the period 24-29 July, 2013. The acoustic measurements were collected simultaneously with other observations which include surface wave and oceanographic measurements, along with high temporal resolution time-lapse imagery of glacier calving events; these other observations are expected to be described in a future archive.
