Princess Elizabeth Land

Princess Elizabeth Land. It is a sector of Antarctica lying between Longitude 73° east and 87° 43' east, forming a significant portion of the Australian Antarctic Territory. The region is bordered by Mac. Robertson Land to the west and Kaiser Wilhelm II Land to the east, with its interior dominated by the vast Antarctic ice sheet. This remote and frigid area is characterized by its extensive ice shelves, including the West Ice Shelf, and notable coastal features such as the Ingrid Christensen Coast.

Geography

The terrain is dominated by the immense Lambert Glacier, one of the world's largest and fastest-moving glaciers, which flows into the Amery Ice Shelf. Key coastal features include the Larsemann Hills and the Vestfold Hills, which contain rare ice-free areas known as Antarctic oases. Other significant geographical landmarks are the Grove Mountains in the interior and the Prince Charles Mountains, which form a major escarpment. The coastline is indented by several bays, including Mawson and Princess Astrid Coast, and faces the Southern Ocean.

History

The land was discovered and named by the British Australian and New Zealand Antarctic Research Expedition (BANZARE) led by Sir Douglas Mawson in 1931, in honor of the future Queen Elizabeth II. This expedition, aboard the RRS Discovery, charted much of the coastline, with further mapping conducted by later operations like Operation Highjump. The area's history is also linked to early whaling activities in the Southern Ocean and subsequent territorial claims during the Heroic Age of Antarctic Exploration. The region fell within the sector claimed by the United Kingdom as the Falkland Islands Dependencies, which was later transferred to Australia.

Exploration and research

Modern scientific investigation began with the establishment of permanent stations, most notably Davis Station by the Australian Antarctic Division in 1957, which remains a hub for research in disciplines like glaciology and marine biology. The Soviet Union also operated Sovetskaya Station inland during the International Geophysical Year. Ongoing research projects involve international collaborations, such as those with the British Antarctic Survey, and focus on ice core drilling in the Aurora Subglacial Basin, cosmic ray detection, and monitoring climate change impacts on the Antarctic ice sheet. Remote sensing via NASA and European Space Agency satellites is critical for these studies.

Climate and environment

The climate is a severe polar climate, with temperatures at Davis Station averaging from -15°C in summer to -30°C in winter, and extreme lows recorded inland. It experiences the Antarctic katabatic wind and full periods of midnight sun and polar night. The environment includes unique ecosystems in the ice-free hills, home to species like Antarctic moss and lichen, while the surrounding waters support Antarctic krill, Weddell seals, and Adélie penguin colonies. The region is protected under the Antarctic Treaty System and designated as an Antarctic Specially Protected Area in several locations to preserve its pristine nature.

Sovereignty and administration

It is administered by Australia as part of the Australian Antarctic Territory, a claim suspended but not invalidated under the Antarctic Treaty. The treaty, signed by original parties including the United States, the Soviet Union, and the United Kingdom, designates the continent for peaceful scientific research. Day-to-day governance and logistical support are managed by the Australian Antarctic Division, with activities regulated by the Protocol on Environmental Protection to the Antarctic Treaty. Australia maintains a strong presence through its stations and collaborates on policy within the Antarctic Treaty Consultative Meeting.
