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.
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
