Iceberg Collision Could Alter Ocean Currents

A very large iceberg recently struck Antarctica, which broke loose a huge piece of ice. This block of ice holds the equivalent of 1/5th the earth's yearly consumption of water. Some scientists are concerned with its possible effects. There is mainly open water in the area the iceberg dislodged, which means there will be massive water displacement in an area very important for ocean currents. The ice could fill the area with cold water, which means it will not sink and rise normally, which is critical for currents. Others suggest that while these weigh as much as 800 billion tons, they will not cause any damage. They are expected to move west in the current.
