Sea of JapanThe Sea of Japan is the marginal sea between the Japanese archipelago, Sakhalin, the Korean Peninsula, and the mainland of the Russian Far East. The Japanese archipelago separates the sea from the Pacific Ocean. Like the Mediterranean Sea, it has almost no tides due to its nearly complete enclosure from the Pacific Ocean. This isolation also affects faunal diversity and salinity, both of which are lower than in the open ocean. The sea has no large islands, bays or capes.
PenguinPenguins are a group of aquatic flightless birds from the order Sphenisciformes (sfᵻˈnɪs@fɔrmiːz) of the family Spheniscidae (sfᵻˈnɪsᵻdiː,_-daI). They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator. Highly adapted for life in the ocean water, penguins have countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch with their bills and swallow whole while swimming.
Cold seepA cold seep (sometimes called a cold vent) is an area of the ocean floor where hydrogen sulfide, methane and other hydrocarbon-rich fluid seepage occurs, often in the form of a brine pool. Cold does not mean that the temperature of the seepage is lower than that of the surrounding sea water. On the contrary, its temperature is often slightly higher. The "cold" is relative to the very warm (at least ) conditions of a hydrothermal vent. Cold seeps constitute a biome supporting several endemic species.
Antarctic Treaty SystemThe Antarctic Treaty and related agreements, collectively known as the Antarctic Treaty System (ATS), regulate international relations with respect to Antarctica, Earth's only continent without a native human population. It was the first arms control agreement established during the Cold War, setting aside the continent as a scientific preserve, establishing freedom of scientific investigation, and banning military activity; for the purposes of the treaty system, Antarctica is defined as all the land and ice shelves south of 60°S latitude.
HobartHobart (ˈhoʊbɑːrt ; Nuennonne/palawa kani: nipaluna) is the capital and most populous city of the island state of Tasmania, Australia. Home to almost half of all Tasmanians, it is the southernmost and least-populated Australian state capital city, and second-smallest if territories are taken into account, before Darwin, Northern Territory. Hobart is located in Tasmania's south-east on the estuary of the River Derwent, making it the most southern of Australia's capital cities.
Tierra del FuegoTierra del Fuego (tiˈɛərə_dɛl_ˈfweɪɡoʊ, ˈtjera ðel ˈfweɣo; Spanish for "Land of Fire", rarely also Fireland in English) is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan. The archipelago consists of the main island, Isla Grande de Tierra del Fuego, with an area of , and a group of many islands, including Cape Horn and Diego Ramírez Islands. Tierra del Fuego is divided between Chile and Argentina, with the latter controlling the eastern half of the main island and the former the western half plus the islands south of Beagle Channel and the southernmost islands.
Polar regions of EarthThe polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles. These high latitudes are dominated by floating sea ice covering much of the Arctic Ocean in the north, and by the Antarctic ice sheet on the continent of Antarctica and the Southern Ocean in the south.
New Holland (Australia)New Holland (Nieuw-Holland) is a historical European name for mainland Australia. The name was first applied to Australia in 1644 by the Dutch seafarer Abel Tasman. The name came for a time to be applied in most European maps to the vaunted "Southern land" or Terra Australis even after its coastline was finally explored. The continent of Antarctica, later named in the 1890s, was still in largely speculative form; it resumed the name Terra Australis (sometimes suffixed Non Cognita, unknown).
Mount ErebusMount Erebus (ˈɛrɪbəs) is the second-highest volcano in Antarctica (after Mount Sidley), the highest active volcano in Antarctica, and the southernmost active volcano on Earth. It is the sixth-highest ultra mountain on the continent. With a summit elevation of , it is located in the Ross Dependency on Ross Island, which is also home to three inactive volcanoes: Mount Terror, Mount Bird, and Mount Terra Nova. The volcano has been active since about 1.
Land and water hemispheresThe land hemisphere and water hemisphere are the hemispheres of Earth containing the largest possible total areas of land and ocean, respectively. By definition (assuming that the entire surface can be classed as either "land" or "ocean"), the two hemispheres do not overlap. Determinations of the hemispheres vary slightly. One determination places the centre of the land hemisphere at (in the city of Nantes, France). The centre of the water hemisphere is the antipode of the centre of the land hemisphere, and is therefore located at (near New Zealand's Bounty Islands in the Pacific Ocean).
