Ice calving is the breaking off of big chunks of ice at the edge of a glacier. It is the sudden release and breaking away of a mass of ice and often makes a huge cracking noise.
This is a close up of floating piece of ice that had only moments before come away from the huge Sawyer glacier found at the end of Tracy Arm located off the Gastineau Channel south of Alaska’s capital Juneau
Whilst I had seen Glaciers before in the mountains to see one at the water’s edge and changing in front of my won eyes was pretty amazing!
