Zachariæ Isstrøm is a major outlet glacier of the Greenland Ice Sheet in northeast Greenland, flowing into the northern part of Jøkel Bay. Named by the Denmark expedition of 1906–08 for Danish naval officer Georg Hugh Robert Zachariæ, it drains 91,780 square kilometers and holds ice equivalent to about 0.5 meter of global sea-level rise. Its measured ice flux rose from 11.7 cubic kilometers per year in 1996 to 15 in 2015. Once near mass balance until 2003, it then began losing mass rapidly, with faster ice flow and a major retreat after breaking loose from a stable position in 2012, making it an important example of changing Greenland ice dynamics.
