We just learned about the Antarctic Sea Ice.
Another part of the ice Antarctica is the Melt Pond.
Sometimes when it gets warm enough for ice to start melting, the top of it will melt and make a little pond on top of the other ice.
This melt pond area is darker than the white snow colored ice, so it warms up more with the sun and can cause it to melt more and get bigger.
Sometimes melt ponds are on top of sea ice.
If the sea ice melt pond keeps getting deeper as it melts, it will melt all the way through the ice.
Melt ponds are fresh water, but if they melt through to the ocean underneath that is salt water.
The salt water will melt the sea ice even more and make a bigger melt pond.
Other times melt ponds are on top of glaciers.
If a melt pond gets big and deep enough it will just hit the land underneath.
Melt ponds can also be underneath a glacier, like an underground lake.
