The Layers of the Arctic Ocean's Water

The very bottom layer of the Arctic Ocean's water is the densest, saltiest, water. This is because water that is very salty sinks to the bottom of the ocean. The second layer of water is the denser, saltier, water. This is the second layer because it is sort of salty so it does not fully sink. The third and top layer is the least salty, and least dense, so it is the very top layer of water. The Arctic Ocean's layers are very large part of the Arctic.
