Zeehan Commonwealth Marine Reserve
Zeehan Commonwealth Marine Reserve is a 19,897 km2 marine protected area within Australian waters located west of Tasmania and extending to near King Island. The reserve was established in 2007 and is part of the South-east Commonwealth Marine Reserve Network. The reserve includes a variety of seabed habitats, including exposed limestone, that provides important habitat for a variety of commercial fish species as well as giant crab. There is a broad depth range, from the shallow continental shelf of about to the abyssal plain with depths of over . Protection The entire Murray marine reserve area is IUCN protected area category VI and has two zones; 'Special Purpose' and 'Multiple Use'.

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or approximately 20% of the water area of Earth#Surface, Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia (continent), Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. The Indian Ocean has large marginal or regional seas, including the Andaman Sea, the Arabian Sea, the Bay of Bengal, and the Laccadive Sea. Geologically, the Indian Ocean is the youngest of the oceans, and it has distinct features such as narrow continental shelf, continental shelves. Its average depth is 3,741 m. It is the warmest ocean, with a significant impact on global climate due to its interaction with the atmosphere. Its waters are affected by the Indian Ocean Walker circulation, resulting in unique oceanic currents and upwelling patterns. The Indian Ocean is ecologically diverse, with important ecosystems such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

It is part of the West Coast Council, along with the seaport Strahan, Tasmania, Strahan and neighbouring mining towns of Rosebery, Tasmania, Rosebery and Queenstown, Tasmania, Queenstown. History The greater Zeehan area was inhabited by the indigenous Peerapper and Tommeginne clans of the Aboriginal Tasmanians#North West, North West group for over 10,000 years prior to the British colonisation of Tasmania. They were greatly coastal peoples, residing in small numbers on a diet consisting of Short-tailed shearwater, muttonbirds, Brown fur seal, seals, swan eggs and cider gum, and constructed bark huts when strong westerly winds brought about rain and icy temperatures.

Protected Areas Of Australia
Protected areas of Australia include Commonwealth and off-shore protected areas managed by the Australian government, as well as protected areas within each of the six states of Australia and two self-governing territories, the Australian Capital Territory and the Northern Territory, which are managed by the eight state and territory governments. Commonwealth and off-shore protected areas in the Australian Capital Territory, the Northern Territory, the Christmas Island Territory, the Cocos (Keeling) Islands Territory, the Norfolk Island Territory and the Australian Antarctic Territory are managed by Director of National Parks, an agency within the Department of Climate Change, Energy, the Environment and Water, with the exception of the Great Barrier Reef Marine Park, which is managed by the Great Barrier Reef Marine Park Authority, a separate body within the department. protected areas cover of Australia's land area, or about 19.75% of the total land area.

Commonwealth Marine Reserves
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 in ...

IUCN Protected Area Category
IUCN protected area categories, or IUCN protected area management categories, are categories used to classify protected areas in a system developed by the International Union for Conservation of Nature (IUCN). The enlisting of such areas is part of a strategy being used toward the conservation of the world's natural environment and biodiversity. The International Union for Conservation of Nature, IUCN has developed the protected area management categories system to define, record and classify the wide variety of specific aims and concerns when categorising protected areas and their objectives. Further supplementary guidelines have been developed specific to marine protected areas (MPAs). This categorisation method is recognised on a global scale by national governments and international bodies such as the United Nations and the Convention on Biological Diversity. Categories Category Ia – strict nature reserve A strict nature reserve (IUCN Category Ia) is an area which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abyssal Plain
An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between . Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth's surface. They are among the flattest, smoothest, and least explored regions on Earth. Abyssal plains are key geologic elements of oceanic basins, the other elements being an elevated mid-ocean ridge and flanking abyssal hills. The creation of the abyssal plain is the result of the spreading of the seafloor (plate tectonics) and the melting of the lower oceanic crust. Magma rises from above the asthenosphere (a layer of the upper mantle), and as this basaltic material reaches the surface at mid-ocean ridges, it forms new oceanic crust, which is constantly pulled sideways by spreading of the seafloor. Abyssal plains result from the blanketing of an originally uneven surface of oceanic crust by fine-grained sediments, mainly clay and silt. Much of th ...

Continental Shelf
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an "''insular shelf''." The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the gradients of the slope and the shelf. Under the United Nations Convention on the Law of the Sea, the name continental shelf was given a legal definition as the stretch of the seabed adjacent to the shores ...
