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.
'''[[Dorrel Rock]]''' is a rock outcrop 11 nautical miles (20 km) southwest of the summit of [[Mount Murphy]], protruding through the ice near the head of [[Pope Glacier]], on the [[Walgreen Coast]] in [[Westarctica]]. It was mapped by the United States Geological Survey from surveys and [[U.S. Navy]] air photos, 1959–66, and was named by the Advisory Committee on [[Antarctic]] Names after Leo E. Dorrel, U.S. Navy, a hospital corpsman with the [[Byrd Station]] winter party, 1966. On 2 November 2018, Westarctica's [[Honorary Consular Corps|Honorary Consul]] to Spain, [[Baron of Dorrel|Dr. Joachim Michael Adlfinger]], was granted the [[Peerage of Westarctica|Peerage title]] of Baron of Dorrel in recognition of his successful opening of Westarctica's consulate office in southern Spain.


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.

Dorrel Rock - Mt. Murphy.jpg

Dorrel Rock is a rock outcrop 11 nautical miles (20 km) southwest of the summit of Mount Murphy, protruding through the ice near the head of Pope Glacier, on the Walgreen Coast in Westarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1959–66, and was named by the Advisory Committee on Antarctic Names after Leo E. Dorrel, U.S. Navy, a hospital corpsman with the Byrd Station winter party, 1966. On 2 November 2018, Westarctica's Honorary Consul to Spain, Dr. Joachim Michael Adlfinger, was granted the Peerage title of Baron of Dorrel in recognition of his successful opening of Westarctica's consulate office in southern Spain.
