Gardner Island
Gardner Island is a largely ice-free island which lies about 3 km west of Broad Peninsula in the southern Vestfold Hills, in Prydz Bay on the Ingrid Christensen Coast of Princess Elizabeth Land, Antarctica. It has been designated an Important Bird Area (IBA) by BirdLife International because it supports about 27,000 breeding pairs of Adélie penguins. Snow petrels also breed on the island. The nearest permanent research station is Australia's Davis Station, 3 km to the east on Broad Peninsula.

Prydz Bay
Prydz Bay is a deep embayment of Antarctica between the Lars Christensen Coast and Ingrid Christensen Coast. The Bay is at the downstream end of a giant glacial drainage system that originates in the East Antarctic interior. The Lambert Glacier flows from Lambert Graben into the Amery Ice Shelf on the south-west side of Prydz Bay. Other major glaciers drain into the southern end of the Amery Ice Shelf at 73° S where the marine part of the system starts at the modern grounding zone. The Amery Ice Shelf extends about 550 km north of the Lambert Glacier grounding zone and occupies a valley between 80 and 200 km wide. Depths to the bed beneath the Amery Ice Shelf are poorly known in detail but it is clearly over-deepened, reaching around -2500 m MSL close to the grounding zone. The Amery Ice Shelf occupies a very large U-shaped valley with exposed nunataks along the flanks reaching 1500 m in elevation and total relief as high as 3000 m. Seaward of the Amery Ice Shelf ...

Princess Elizabeth Land
Princess Elizabeth Land is the sector of Antarctica between longitude 73° east and Cape Penck (at 87°43' east). The sector is claimed by Australia as part of the Australian Antarctic Territory, although this claim is not widely recognized. Geography Princess Elizabeth Land is located between 64°56'S and 90°00'S and between 73°35' E and 87°43'E. It is divided into two sectors: * Ingrid Christensen Coast, 73°35'E to 81°24'E * Leopold and Astrid Coast, 81°24'E to 87°43'E It is bounded on the west by Amery Ice Shelf, Mac. Robertson Land, and on the east by Kaiser Wilhelm II Land. Exploration Princess Elizabeth Land was discovered on 9 February 1931, by the British Australian and New Zealand Antarctic Research Expedition (BANZARE) (1929–31) under Sir Douglas Mawson. Princess Elizabeth Land was named by Mawson after Princess Elizabeth, granddaughter of King George V who reigned at the time as King of Australia, among his other titles. Princess Elizabeth would later g ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ...

Vestfold Hills
The Vestfold Hills are rounded, rocky, coastal hills, in extent, on the north side of Sorsdal Glacier on the Ingrid Christensen Coast of Princess Elizabeth Land, Antarctica. The hills are subdivided by three west-trending peninsulas bounded by narrow fjords. Most of the hills range between in height, with the highest summit reaching nearly . Geography The Vestfold Hills are largely snow and ice-free and are thus classified as an Antarctic oasis. They contain a great variety of lake systems with over 300 lakes and ponds including what is possibly the largest concentration of meromictic (stratified) lakes in the world. This region contains 37 permanently stratified water bodies, including six marine basins and seven seasonally isolated marine basins (SIMBs). These stratified basins also have great variety. They range in salinity from 4 g L−1 to 235 g L−1, in temperature from , in depth from , in area from and surface level from below to above sea level. The region contains ...

Ingrid Christensen Coast
The Ingrid Christensen Coast is that portion of the coast of Antarctica lying between Jennings Promontory, in 72°33′E, and the western end of the West Ice Shelf in 81°24′E. It is located in the western half of Princess Elizabeth Land, just east of the Amery Ice Shelf. Exploration The coast was discovered and a landing made on the Vestfold Hills on February 20, 1935, by Captain Klarius Mikkelsen in the ''Tórshavn'', a vessel owned by Norwegian whaling magnate Lars Christensen Lars Christensen (6 April 1884 – 10 December 1965) was a Norwegian shipowner and whaling magnate. He was also a philanthropist with a keen interest in the exploration of Antarctica. Career Lars Christensen was born at Sandar in Vestfold, No .... It was named for Ingrid Christensen, wife of Lars, who sailed in Antarctic waters with her husband, and was one of the first women to visit Antarctica. The southwestern portion of this coast was discovered and photographed from the air by U.S. Navy O ...

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking. History In 1985, following a specific request from the European Economic Community, Birdlife International ...

Adélie Penguin
The Adélie penguin (''Pygoscelis adeliae'') is a species of penguin common along the entire coast of the Antarctic continent, which is the only place where it is found. It is the most widespread penguin species, and, along with the emperor penguin, is the most southerly distributed of all penguins. It is named after Adélie Land, in turn named for Adèle Dumont d'Urville, who was married to French explorer Jules Dumont d'Urville, who first discovered this penguin in 1840. Adélie penguins obtain their food by both predation and foraging, with a diet of mainly krill and fish. Taxonomy and systematics The first Adélie penguin specimens were collected by crew members of French explorer Jules Dumont d'Urville on his expedition to Antarctica in the late 1830s and early 1840s. Jacques Bernard Hombron and Honoré Jacquinot, two French surgeons who doubled as naturalists on the journey, described the bird for science in 1841, giving it the scientific name ''Catarrhactes adeli ...

Snow Petrel
The snow petrel (''Pagodroma nivea'') is the only member of the genus ''Pagodroma.'' It is one of only three birds that has been seen at the Geographic South Pole, along with the Antarctic petrel and the south polar skua, which have the most southerly breeding sites of any bird, inland in Antarctica. Taxonomy The snow petrel was described in 1777 by the German naturalist Georg Forster in his book ''A Voyage Round the World''. He had accompanied James Cook on Cook's second voyage to the Pacific. We particularly observed a petrel, about the size of a pigeon, entirely white, with a black bill and blueish feet; it constantly appeared about the icy masses, and may be looked upon as a sure fore-runner of ice. Forster placed the snow petrel in the genus ''Procellaria'' that had been erected for the petrels by Carl Linnaeus in 1758 and coined the binomial name ''Procellaria nivea''. The snow petrel is now the only species placed in the genus ''Pagodroma'' that was introduced for the ...

Davis Station
The Davis Station, commonly called Davis, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Davis is situated on the coast of Cooperation Sea in Princess Elizabeth Land, Ingrid Christensen Coast in the Australian Antarctic Territory, a territory claimed by Australia. Davis lies in the Antarctic oasis, a remarkable ice free area known as the Vestfold Hills. Davis was named in honour of Captain John King Davis. Davis was listed on the Register of the National Estate on 26 October 1999 and has been included on the Commonwealth Heritage List as an indicative place, due to the condition of buildings and structures that varies from no longer exists/demolished due to poor condition, through to very good condition. Purpose Davis is a base for scientific research programs including the study of viruses and bacteria using molecular genetic techniques in glacial lakes, the impact of environmental change and pollution ...
