3. But Dotson connects to Thwaites, and the new research finds that a huge, upside down canyon is being carved out of its ice from below.

4. Petermann ice shelf in Greenland also has one of these canyons down its center and there could well be more

6. It can concentrate its energy in one place sometimes, with powerful results -- thus, the canyon cuts almost halfway through Dotson.

7. & combined w/ new calving pattern at Pine Island Glacier, this suggests continuing, marked change in this region
