Short summary
This paper aims to improve the understanding of variations in ocean conditions around the Greenland Ice Sheet, which have been called upon to explain recent glacier change. Changes in iceberg elevation over time, measured using satellite data, are used to estimate average melt rates. We find that iceberg melt rates generally decrease with latitude and increase with keel depth and can be used to characterize ocean conditions at Greenland's inaccessible marine margins.
