We quantitatively relate the sizes of icebergs to the properties of the icequakes they produce.  Then, using 18 months of seismic recordings (~350,000 calving icequakes), we examine variations in calving flux.  Iceberg calving rates vary seasonally based on rates of submarine melt, and on hourly/daily timescales based on tidal stage.
