An '''[[iceberg]]''' is a large piece of freshwater [[ice]] that has broken off a [[glacier]] or an [[Ice-shelf|ice shelf]] and is floating freely in open water. It may subsequently become frozen into [[pack ice]] (one form of sea ice). As it drifts into shallower waters, it may come into contact with the seabed, a process referred to as seabed gouging by ice. About 90% of an iceberg is below the surface of the water.
The '''[[Whitmore Mountains]]''' are an isolated mountain range of the Transantarctic Mountains System, located in the [[Marie Byrd Land]] region of [[Westarctica]]. They consist of three small mountains and a cluster of [[nunatak]]s arranged in a semicircular pattern extending over 15 miles. When researching the National Geographic Atlas map of [[Antarctica]], [[Grand Duke Travis]] was inspired by the fact that the Whitmore Mountains were located in the unclaimed section of Marie Byrd Land and they shared the name of his childhood best friend, [[Viscount of Whitmore|Neil Whitmoyer]]. Were it not for this immediate confirmation, it is entirely possible the Grand Duke might not have decided to move forward with his plan to claim Westarctica.


In addition to size classification, icebergs can be classified on the basis of their shape. The two basic types of iceberg forms are tabular and non-tabular. Tabular icebergs have steep sides and a flat top, much like a plateau, with a length-to-height ratio of more than 5:1. This type of iceberg, also known as an ice island, can be quite large, as in the case of Pobeda Ice Island. [[Antarctic]] icebergs formed by breaking off from an [[ice-shelf|ice shelf]], such as the [[Ross Ice Shelf]] or [[Filchner-Ronne Ice Shelf]], are typically tabular. The largest icebergs in the world are formed this way.

Whitmore Mountains - Mt Chapman.jpg

The Whitmore Mountains are an isolated mountain range of the Transantarctic Mountains System, located in the Marie Byrd Land region of Westarctica. They consist of three small mountains and a cluster of nunataks arranged in a semicircular pattern extending over 15 miles. When researching the National Geographic Atlas map of Antarctica, Grand Duke Travis was inspired by the fact that the Whitmore Mountains were located in the unclaimed section of Marie Byrd Land and they shared the name of his childhood best friend, Neil Whitmoyer. Were it not for this immediate confirmation, it is entirely possible the Grand Duke might not have decided to move forward with his plan to claim Westarctica.
