Ice mass is a term used to describe large masses of ice that are found in the polar regions. It includes two main types of ice, floes and bergs. Floes are large pieces of floating ice that are found in the ocean, while bergs are large chunks of ice that have broken off from glaciers or ice shelves and are found in the sea. Both floes and bergs are important components of the Earth's climate system, as they help to regulate global temperatures.
