Original caption: Caves formed from water smashing against the base of an iceberg can become arches and holes in icebergs when they roll over as their centre of gravity shifts. Icebergs in Antarctica circulate with the Antarctic Circumpolar Current, the strongest current in the world, moving more than 4.8 billion cubic feet of water per second. In the Weddell Sea, icebergs that spin out of this fast current drift into the Iceberg graveyard. An iceberg is only one-fifth above water. --- Image by © Seth Resnick/Science Faction/Corbis
