Donovan Islands
The Donovan Islands are a chain of about 8 islands lying well offshore, about northwest of Clark Peninsula in the eastern part of Vincennes Bay. First mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47, they were photographed from the air by the Australian National Antarctic Research Expeditions in January 1956, and were named after J. Donovan, Administrative Officer of the Antarctic Division, Melbourne, and leader of a number of relief expeditions to Heard Island and Macquarie Island Macquarie Island is an island in the southwestern Pacific Ocean, about halfway between New Zealand and Antarctica. Regionally part of Oceania and politically a part of Tasmania, Australia, since 1900, it became a Tasmanian State Reserve in 197 ....

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clark Peninsula
Clark Peninsula is a rocky peninsula, about long and wide, lying north-east of Australia's Casey Station at the north side of Newcomb Bay on the Budd Coast of Wilkes Land in Antarctica. History The peninsula was first mapped from aerial photographs taken by the US Navy's Operation Highjump in February 1947 and thought to be an island connected by a steep snow ramp to the continental ice overlying Budd Coast. It was subsequently photographed from the air by the Soviet expedition of 1956 and the Australian National Antarctic Research Expeditions (ANARE) of 1956 and 1962. The Wilkes Station party of 1957, whose headquarters were on Clark, determined that it was a peninsula rather than an island. This party was led by Scientific Station Leader Carl R. Eklund, who conducted many ground surveys and named many of the peninsula's features. The peninsula itself was named by the Advisory Committee on Antarctic Names (US-ACAN) for Captain John E. Clark, captain of , flagship of the we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vincennes Bay
Vincennes Bay is a large V-shaped bay, 105 km (65 mi) wide at its entrance between Cape Nutt and Cape Folger in Antarctica, marked by several large, steep glaciers near its head, lying along Knox and Budd Coasts. It was photographed from the air by US Navy Operation Highjump in 1946–47. The bay was entered in January 1948 by US Navy Operation Windmill icebreakers Burton Island and stations in the Windmill Islands in the NE portion of the bay. Named by the US-ACAN for the sloop of war , flagship of the USEE under Wilkes, from which a series of coastal landfalls along Wilkes Land were discovered and plotted during January–February 1840. Wilkes' chart suggests a possible coastal recession corresponding closely with the longitudinal limits for Vincennes Bay, although pack ice conditions prevented close reconnaissance by the USEE of the coast in this immediate area. Vincennes Bay is roughly triangular, 120 km north–south and 150 km east–west at its nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian National Antarctic Research Expeditions
The Australian National Antarctic Research Expeditions (ANARE ) is the historical name for the Australian Antarctic Program (AAp) administered for Australia by the Australian Antarctic Division (AAD). History Australia has had a long involvement in south polar regions since as early as Douglas Mawson's Australasian Antarctic Expedition in 1911. Further Australian exploration of the Antarctic continent was conducted during the British Australian and New Zealand Antarctic Research Expedition (BANZARE), which was conducted over the years 1929–1931. The Australian National Antarctic Research Expeditions were established in 1947 with expeditions to Macquarie Island and Heard Island. In 1948 the Australian Antarctic Division (AAD) was established to administer the expedition program. ANARE Name The name ANARE fell out of official use in the early 2000s. However current and former Australian Antarctic expeditioners continue to use the term informally as a means of identifica ...

Melbourne
Melbourne ( ; Boonwurrung/Woiwurrung: ''Narrm'' or ''Naarm'') is the capital and most populous city of the Australian state of Victoria, and the second-most populous city in both Australia and Oceania. Its name generally refers to a metropolitan area known as Greater Melbourne, comprising an urban agglomeration of 31 local municipalities, although the name is also used specifically for the local municipality of City of Melbourne based around its central business area. The metropolis occupies much of the northern and eastern coastlines of Port Phillip Bay and spreads into the Mornington Peninsula, part of West Gippsland, as well as the hinterlands towards the Yarra Valley, the Dandenong and Macedon Ranges. It has a population over 5 million (19% of the population of Australia, as per 2021 census), mostly residing to the east side of the city centre, and its inhabitants are commonly referred to as "Melburnians". The area of Melbourne has been home to Aboriginal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heard Island
The Territory of Heard Island and McDonald Islands (HIMI) is an Australian external territory comprising a volcanic group of mostly barren Antarctic islands, about two-thirds of the way from Madagascar to Antarctica. The group's overall size is in area and it has of coastline. Discovered in the mid-19th century, the islands lie on the Kerguelen Plateau in the Indian Ocean and have been an Australian territory since 1947. They contain Australia's only two active volcanoes. The summit of one, Mawson Peak, is higher than any mountain in all other Australian states or territories, except Dome Argus, Mount McClintock and Mount Menzies in the Australian Antarctic Territory. The islands are among the most remote places on Earth: They are located about southwest of Perth, southwest of Cape Leeuwin, Australia, southeast of South Africa, southeast of Madagascar, north of Antarctica, and southeast of the Kerguelen Islands (part of French Southern and Antarctic Lands). The isla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macquarie Island
Macquarie Island is an island in the southwestern Pacific Ocean, about halfway between New Zealand and Antarctica. Regionally part of Oceania and politically a part of Tasmania, Australia, since 1900, it became a Tasmanian State Reserve in 1978 and was inscribed as a UNESCO World Heritage Site in 1997. It was a part of Esperance Municipality until 1993, when the municipality was merged with other municipalities to form Huon Valley Council. The island is home to the entire royal penguin population during their annual nesting season. Ecologically, the island is part of the Antipodes Subantarctic Islands tundra ecoregion. Since 1948, the Australian Antarctic Division (AAD) has maintained a permanent base, the Macquarie Island Station, on the isthmus at the northern end of the island at the foot of Wireless Hill. The population of the base, constituting the island's only human inhabitants, usually varies from 20 to 40 people over the year. A heliport is located nearby. In Septemb ...
