Ice islands (immense tabular-shaped icebergs) calve from ice shelves and ice tongues in northwest Greenland and northern Ellesmere Island. As they drift freely in the ocean they can make their way southwards where they are often viewed as hazards to navigation and offshore infrastructure. They also deteriorate over time and may produce numerous, smaller ice hazards (i.e., icebergs, bergy bits and growlers). Ice islands and icebergs also transport large amounts freshwater far from their origin and upon deterioration this freshwater will affect the physical, chemical and biological nature of the surrounding ocean waters. At WIRL, we study the deterioration of ice islands and icebergs, their drift trajectories, their influence on the ocean around them and how they can best be detected in satellite imagery.
