Once in the water, roughly six-sevenths of an iceberg is below the surface. Since there is so much of the iceberg below the waterline, deeper currents move the mass more than winds or waves. One of the currents that moves icebergs in the North Atlantic is the Labrador Current.
1. Why are deeper currents, more than waves or wind, the moving force behind icebergs?
2. What factors might affect whether or not an iceberg moves far enough south to enter the shipping lanes?
