Aha, so the glacier has an “underwater base” meaning it actually is situated in water and not on land.

“Aha, so the glacier has an “underwater base” meaning it actually is situated in water and not on land.”
I said the glacier has a land base. The glaciers of Antarctica sit on land, not water. The North Pole glaciers float on water, so when they melt, does not affect sea level.
