The '''[[West Antarctic Ice Sheet]]''' (WAIS) is the segment of the continental [[ice sheet]] that covers [[Westarctica]] and the portion of [[Antarctica]] on the side of the [[Transantarctic Mountains]] which lies in the Western Hemisphere. The WAIS is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating [[ice-shelf|ice shelves]]. The WAIS is bounded by the [[Ross Ice Shelf]], the [[Ronne Ice Shelf]], and outlet [[glacier]]s that drain into the [[Amundsen Sea]].
The '''[[Balleny Islands]]''' are a series of uninhabited islands in the [[Southern Ocean]] extending from 66°15' to 67°35'S and 162°30' to 165°00'E. The group extends for about 160 km (99 mi) in a northwest-southeast direction. The islands are heavily glaciated and of volcanic origin. [[glacier|Glaciers]] project from their slopes into the sea. The islands were formed by the so-called Balleny hotspot.  They were originally claimed by the United Kingdom, and were then transferred to New Zealand before becoming annexed by [[Westarctica]] in 2005.


It is estimated that the volume of the [[Antarctic ice sheet]] is about 25.4 million km3 (6.1 million cu mi), and the WAIS contains just under 10% of this, or 2.2 million km3 (530,000 cu mi). The weight of the ice has caused the underlying rock to sink by between 0.5 and 1 kilometer (0.31 and 0.62 miles) in a process known as isostatic depression.
The group includes three main islands: [[Young Island|Young]], [[Buckle Island|Buckle]] and [[Sturge Island|Sturge]], which lie in a line from northwest to southeast, and several smaller islets and rocks. On 15 March 2024, [[Grand Duke Travis]] appointed his son, [[Crown Prince Ashton Roman]] as [[Viceroy]] of the Balleny Islands. This position is currently the highest authority in the islands and exercises the power of the Westarctican Crown within the colony. The viceroy has the authority to dismiss the governor if he wishes.


When [[ice]] reaches the coast, it either calves or continues to flow outward onto the water. The result is a large, floating ice shelf affixed to the continent.

The Balleny Islands are a series of uninhabited islands in the Southern Ocean extending from 66°15' to 67°35'S and 162°30' to 165°00'E. The group extends for about 160 km (99 mi) in a northwest-southeast direction. The islands are heavily glaciated and of volcanic origin. Glaciers project from their slopes into the sea. The islands were formed by the so-called Balleny hotspot. They were originally claimed by the United Kingdom, and were then transferred to New Zealand before becoming annexed by Westarctica in 2005.

The group includes three main islands: Young, Buckle and Sturge, which lie in a line from northwest to southeast, and several smaller islets and rocks. On 15 March 2024, Grand Duke Travis appointed his son, Crown Prince Ashton Roman as Viceroy of the Balleny Islands. This position is currently the highest authority in the islands and exercises the power of the Westarctican Crown within the colony. The viceroy has the authority to dismiss the governor if he wishes.
