Facts about Iceberg Dynamics

1. 05

   The rolling and capsizing of icebergs transfers enormous energy, generating seismic waves detectable by instruments thousands of kilometers away.

   Iceberg dynamics involve a process called 'calving,' where large chunks of ice break off glaciers or ice shelves under the stress of gravity and ocean forces.

   Melting icebergs release trapped ancient air bubbles and freshwater, measurably altering local ocean salinity and affecting marine circulation patterns.

   Tabular icebergs, which calve from ice shelves in Antarctica, can extend hundreds of kilometers in length and dwarf many countries in surface area.

   Approximately 90 percent of an iceberg's total mass lies below the ocean surface, making only a small fraction visible above water.
