Twice a day, the ocean lifts a glacier. The movement is small, sometimes only a few centimeters. It happens quietly, far from cities and coastlines. But along the edges of glaciers, these subtle tidal pulses help control how quickly ice flows into the sea.
Working with Dr. Wesley Van Wychen, Dr. Jae Hun Kim studies how glaciers in Greenland and the Canadian Arctic respond to the rhythm of the tides. Using radar, he tracks the grounding line, the place where a glacier lifts off bedrock and begins to float. This narrow boundary plays a crucial role in glacier mass loss.
