High tide floating ice shelves
WebIce shelves, the floating extensions of the Antarctic and Greenland ice sheets, are not simply resting on the ocean waters: they rise, fall and bend with the tides. Ultimately, these oceanic motions impact the flow of ice coming from the glaciers that these ice shelves buttress.
