Original caption: An iceberg drifts in the iceberg graveyard. 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. Icebergs sometimes spin out of this current and drift. The Iceberg graveyard is an area where many icebergs from the Weddell Sea end up creating a spectacular site. Icebergs come from a glacier or an ice shelf. Only one-fifth of an iceberg is above the water. --- Image by © Seth Resnick/Science Faction/Corbis
