Skiing past grounded ice-berg

The tip of the "ice-berg." Everybody knows that most of an iceberg lies under the water, but most don't know that the amount beneath the surface varies from about 50% to 99%. The cause of the variation is largely in the amount of air that is trapped in the ice so affecting its buoyancy. An average iceberg will be about 80-90% beneath the surface. Very low lying pieces of ice of whatever size in the water are known as "growlers". These often have a green tinge to them.  

They are known as growlers because they present a particular hazard to shipping with the small amount visible above the water and the colour making them especially difficult to see and therefore especially dangerous.
