Columbia Glacier Retreating - Geophysical Institute
2024年12月5日 · Columbia Glacier moves toward the sea at the rate of about one to three kilometers per year (about a mile) along its center line and roughly twice that fast along the edges where the ice is thinner. In order for the leading edge to actually move backward, therefore, the calving rate in the later months of the year must be phenomenal.
