| Description: |
Researchers for the first time have used seismic sensors to track meltwater flowing through glaciers and into the ocean, an essential step to understanding the future of the world's largest glaciers as climate changes. The new technique offers scientists a tool for tracking meltwater at glaciers that end in the ocean, called tidewater glaciers. Unlike landlocked glaciers, where scientists can simply measure the meltwater flowing in glacial rivers, there previously had not been a method available to track what's occurring within tidewater glaciers.
