IMCRA Meso-scale Bioregions
The Integrated Marine and Coastal Regionalisation of Australia (IMCRA), formerly the Interim Marine and Coastal Regionalisation for Australia, is a biogeographic regionalisation of the oceanic waters of Australia's exclusive economic zone (EEZ). As of 2008, the most recent version is IMCRA Version 4.0. IMCRA actually defines two bioregionalisations: a benthic bioregionalisation, based on biogeography of fish together with geophysical data; and a pelagic bioregionalisation, base on oceanographic characteristics. The benthic bioregionalisation incorporates three separate regionalisations: #A regionalisation of the EEZ into provincial bioregions, based on the biogeography of bottom dwelling fishes. In IMCRA 4.0, 41 provincial bioregions, consisting of 24 ''provinces'' and 17 ''transitions''. #A regionalisation of the continental shelf into ''meso-scale regions'' based on biological and physical characters, and the distance from the coast. In IMCRA 4.0 there are 60 meso-scale reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biogeography
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area.Brown University, "Biogeography." Accessed February 24, 2014. . Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms. Knowledge of spatial variation in the numbers and types of organisms is as vital to us today as it was to our early human ancestors, as we adapt to heterogeneous but geographically predictable environments. Biogeography is an integrative field of inquiry that unites concepts and information from ecology, evolutionary biology, taxonomy, geology, physical geography, palaeontology, and climatology.Dansereau, Pierre. 1957 ...

Van Diemens Gulf
Van Diemen Gulf is a gulf in the Northern Territory of Australia. It connects to the Timor Sea in the north via Dundas Strait. Most of its area is also gazetted as a locality with the name Van Diemen Gulf. History The gulf was named after the Dutch colonial governor, Anthony van Diemen (1593–1645). Phillip Parker King and his crew in the 76-tonne cutter surveyed the coastline in early 1818, encountering local Aboriginal people and proas sailed by Makassans, and passed by the Gulf on other voyages. Geography The gulf connects to the Timor Sea in the north via Dundas Strait, and is also connected to the Beagle Gulf in the west by the Clarence Strait. It is partially enclosed by Melville Island and the Cobourg Peninsula, and measures about by . Rivers draining into the Gulf include the South Alligator River, the East Alligator River, the Mary River, Wildman River and the Adelaide River. The Kakadu National Park adjoins its south-east coast.

Torres Strait
The Torres Strait (), also known as Zenadh Kes, is a strait between Australia and the Melanesian island of New Guinea. It is wide at its narrowest extent. To the south is Cape York Peninsula, the northernmost extremity of the Australian mainland. To the north is the Western Province of Papua New Guinea. It is named after the Spanish navigator Luís Vaz de Torres, who sailed through the strait in 1606. Prehistory The islands of the Torres Strait have been inhabited by humans for at least 2,500 years and possibly much longer. The various Torres Strait Islander communities have a unique culture and long-standing history with the islands and nearby coastlines. Their maritime-based trade and interactions with the Papuans to the north and the Australian Aboriginal communities have maintained a steady cultural diffusion among the three societal groups, dating back thousands of years. History The first recorded European navigation of the strait was by Luís Vaz de Torres, a pilot ... [...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 ...

Great Australian Bight
The Great Australian Bight is a large oceanic bight, or open bay, off the central and western portions of the southern coastline of mainland Australia. Extent Two definitions of the extent are in use – one used by the International Hydrographic Organization (IHO) and the other used by the Australian Hydrographic Service (AHS). The IHO defines the Great Australian Bight as having the following limits: ''On the North.'' The south coast of the Australian mainland. ''On the South.'' A line joining West Cape Howe () Australia to South West Cape, Tasmania. ''On the East.'' A line from Cape Otway, Victoria to King Island and thence to Cape Grim, the northwest extreme of Tasmania. The AHS defines the bight with a smaller area, from Cape Pasley, Western Australia, to Cape Carnot, South Australia - a distance of . Much of the bight lies due south of the expansive Nullarbor Plain, which straddles South Australia and Western Australia. The Eyre Highway passes close to the cli ...
