Tabular Iceberg

Tabular icebergs are huge chunks of frozen saltwater that break off from ice shelves. They do not raise sea level when they break off, because they were already in the ocean. But they can have a significant effect on the ability of creatures such as penguins to find food. Many more of them are breaking off as the climate warms.
