A new model yields insights into glaciers’ retreats and advances, shows cyclic nature of tidewater glaciers

A University of Alaska Fairbanks study looking at the physics of tidewater glaciers has yielded new insights into what drives their retreat-and-advance cycles and the role that climate plays in these cycles.

Lead author and UAF geophysics doctoral student Douglas Brinkerhoff said the study in Nature Communications reveals that shifting sediments drive the cycles among tidewater glaciers in temperate climates such as southern Alaska.

BINGO.

Bed interactions have been known for decades to be HUGE factors in the advance/retreat of glaciers, especially at the terminus (snout).

If that weren't the case, those planes which made a forced landing in Greenland during WWII wouldn't have wound up buried in a hundred feet of ice, and those bodies from the missing India Air crafts that crashed in the Alps wouldn't have been concealed in the first place.
