Tasman Fracture
The Tasman Fracture is a deep Oceanic trench, ocean trench off the South West Tasmania, south west coast of Tasmania. It is located within the boundaries of the Tasman Fracture Commonwealth Marine Reserve which lies within the Tasmania Province of the Integrated Marine and Coastal Regionalisation of Australia.

Oceanic Trench
Oceanic trenches are prominent, long, narrow topography, topographic depression (geology), depressions of the seabed, ocean floor. They are typically wide and below the level of the surrounding oceanic floor, but can be thousands of kilometers in length. There are about of oceanic trenches worldwide, mostly around the Pacific Ocean, but also in the eastern Indian Ocean and a few other locations. The greatest ocean depth measured is in the Challenger Deep of the Mariana Trench, at a depth of below sea level. Oceanic trenches are a feature of the Earth's distinctive plate tectonics. They mark the locations of convergent boundary, convergent plate boundaries, along which lithosphere, lithospheric plates move towards each other at rates that vary from a few millimeters to over ten centimeters per year. Oceanic lithosphere moves into trenches at a global rate of about per year. A trench marks the position at which the flexed, subduction, subducting slab (geology), slab begins to d ...

South West Tasmania
South West Tasmania is a region in Tasmania that has evoked curiosity and wonder during the period of European presence on the island. Initially relatively unexplored by Europeans, in the mid-twentieth century the area was considered for its potential resources for development. Much of the area is now protected within the Southwest National Park and as part of the Tasmanian Wilderness World Heritage Area. The most notable controversy occurring in the region was the flooding of Lake Pedder as part of a hydro-electric development, in 1972. This was followed, further north, by the proposed damming of the Franklin River in the early 1980s, which did not proceed. Southwest is a locality that covers most of the region. The locality (and therefore the region) is in the local government areas of Derwent Valley (29%), Huon Valley (20%), Central Highlands (7%) and West Coast (44%). Its central point, near the encircled locality of Strathgordon, is about west of the town of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tasmania
Tasmania (; palawa kani: ''Lutruwita'') is an island States and territories of Australia, state of Australia. It is located to the south of the Mainland Australia, Australian mainland, and is separated from it by the Bass Strait. The state encompasses the main island of Tasmania, the List of islands by area#Islands, 26th-largest island in the world, and the List of islands of Tasmania, surrounding 1000 islands. It is Australia's smallest and least populous state, with 573,479 residents . The List of Australian capital cities, state capital and largest city is Hobart, with around 40% of the population living in the Greater Hobart area. Estimated resident population, 30 June 2017. Tasmania is the most decentralised state in Australia, with the lowest proportion of its residents living within its capital city. Tasmania's main island was first inhabited by Aboriginal Australians, Aboriginal peoples, who today generally identify as Palawa or Pakana. It is believed that Abori ...

Tasman Fracture Commonwealth Marine Reserve
Tasman Fracture Commonwealth Marine Reserve is a 42,502 km2 marine protected area within Australian waters located off the coast of south-west Tasmania. It extends to the southerly limits of the Australian exclusive economic zone in the Indian Ocean and encompasses the Tasman Fracture. The reserve was established in 2007 and is part of the South-east Commonwealth Marine Reserve Network. The reserve includes a number of undersea peaks rising to less than below the sea surface that provide habitat to deepwater hard corals. The reserve is also habitat to many seabirds, seals and cetaceans, such as dolphins and killer whales. The fauna of this reserve includes subantarctic fishes and seabed invertebrates. Biodiversity within the reserve is influenced by the most easterly extent of the Zeehan Current. Protection Most of the Tasman Fracture marine reserve area is IUCN protected area category VI, however there are multiple zoned areas within the reserve with different prot ...

Tasmania Province
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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South-east Commonwealth Marine Reserve Network
Australian marine parks (formerly Commonwealth marine reserves) are marine protected areas located within Australian waters and are managed by the Australian government. These waters generally extend from three nautical miles off the coast to the outer limit of Australia’s Exclusive Economic Zone at 200 nautical miles while marine protected areas located closer in-shore are the responsibility of the states or the Northern Territory. History Under the Howard government the world’s first Oceans Policy was developed. It included the creation of the Great Australian Bight Marine Park in 1998, greatly increased protection of the Great Barrier Reef Marine Park, and in 2007, established a series of large marine parks in Australia's south-east, now collectively known as the South-east Marine Parks Network. 2012 marine parks In 2012, the Australian government under Labor/Kevin Rudd revealed plans to create the world's largest marine reserve network, made up of five main zones ...
