Abstract Details

2012, Master of Science, Ohio State University, Geological Sciences.
While iceberg calving makes up a substantial portion of mass loss for marine-terminating glaciers, these dynamics remain poorly represented in predictions of sea-level rise and large-scale climate models, requiring more robust observational datasets. Breiðamerkurjökull glacier functions as a uniquely controlled field setting for obtaining a wide variety of environmental and geodetic measurements in conjunction with monitoring calving flux, making it possible to more carefully constrain the sometimes-contradictory relationships between calving and environmental conditions observed in previous studies. A time-lapse camera and water level logger were placed roughly 1 km from the glacier ice front to monitor ice loss and iceberg-generated tsunamis from April to September 2011. This record was used to estimate the volume of ice lost by calving during this period and obtain calving rates on hourly, daily, and weekly timescales. Weather, tide, and contemporaneous records of the temperature-salinity structure of the lagoon were used to examine relationships between these factors and calving. Calving was shown to be more common during the falling tide in both spring and fall.
