The Northwest Shelf Province, also known as Exmouth to Broome, [1] is a biogeographic region of Australia's continental shelf.
The Northwest Shelf Province, also known as Exmouth to Broome, [1] is a biogeographic region of Australia's continental shelf.
The Northwest Shelf Province includes the coastal waters and continental shelf of north-western Western Australia between North West Cape and Cape Leveque. It has an area of 238,759 km2, extending from the shore to 200 m depth. It varies in width from about 50 km at Exmouth Gulf to more than 250 km off Cape Leveque. [2]
The Northwest Shelf Province adjoins the Central Western Shelf Transition or Ningaloo region on the southwest. The Northwest Shelf Transition lies east of Cape Leveque. To the north the continental slope descends towards the Indian Ocean's abyssal plain.
The waters are tropical. Surface waters are derived from the Indonesian Throughflow, and circulate through the province via branches of the South Equatorial and Eastern Gyral currents. [3] Tidal ranges are generally high.
The Northwest Coast, including the Pilbara Coast and Eighty Mile Beach, is the most cyclone-prone region of the entire Australian coastline. On average two cyclones cross the coast each year, one of which is severe. [4]
The Integrated Marine and Coastal Regionalisation of Australia (IMCRA) identifies five distinct meso-scale bioregions that make up the province. [5]
The Bass Strait Shelf Province is a biogeographic region of Australia's coastal and continental shelf waters. It covers the central Bass Strait between Tasmania and the southern Australian mainland. It is a provincial level bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system. The Bassian and adjacent Tasmanian Shelf provinces correspond to the Bassian marine ecoregion in the WWF's Marine Ecoregions of the World system.
The Central Eastern Shelf Province is a biogeographic region of Australia's coastal and continental shelf waters. It includes the warm temperate coastal waters of eastern Australia. It is a provincial level bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system. It corresponds to the Manning-Hawkesbury marine ecoregion in the WWF's Marine Ecoregions of the World system.
Tweed–Moreton, also known as the Central Eastern Shelf Transition, is a marine biogeographic region of eastern Australia.
The Central Western Shelf Province, also known as the Shark Bay marine ecoregion, is a biogeographic region of Australia's continental shelf and coastal waters. It includes the subtropical coastal waters of Western Australia.
The Northeast Shelf Province is a biogeographic region of Australia's coastal and continental shelf waters. It includes the tropical coastal waters of the central and southern Great Barrier Reef in northeastern Australia. It is a provincial level bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system. It corresponds to the Central and Southern Great Barrier Reef marine ecoregion in the WWF's Marine Ecoregions of the World system.
The Northeast Shelf Transition is a biogeographic region of Australia's coastal and continental shelf waters. It includes the tropical coastal waters of the northern Great Barrier Reef and the Torres Strait in northeastern-most Australia. It is a provincial level bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system. It corresponds to the Torres Strait and Northern Great Barrier Reef marine ecoregion in the WWF's Marine Ecoregions of the World system.
The Northern Shelf Province, also known as Arnhem Coast to Gulf of Carpentaria, is a biogeographic region of Australia's continental shelf. It includes the coastal waters of Arnhem Land and the Gulf of Carpentaria in Northern Australia.
The Northwest Shelf Transition, also known as Bonaparte Coast, is a biogeographic region of Australia's continental shelf. It adjoins the Kimberley region of Western Australia and the adjacent coast of the Northern Territory.
The Southeast Shelf Transition is a biogeographic region of Australia's coastal and continental shelf waters. It covers a portion of Australia's southeastern coast, from southern New South Wales to eastern Victoria, including the islands of the Kent Group and Furneaux Group at the eastern end of the Bass Strait. It is a provincial level bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system, and is a transitional region between the warm temperate Central Eastern Shelf Province to the northwest and the cool temperate Bass Strait Shelf and Tasmanian Shelf provinces to the west and south. It corresponds to the Cape Howe marine ecoregion in the WWF's Marine Ecoregions of the World system.
The Southwest Shelf Province, also known as the Leeuwin marine ecoregion, is a biogeographic region of Australia's continental shelf. It includes the temperate coastal waters of Southwest Australia.
The Southwest Shelf Transition, also known as the Houtman marine ecoregion, is a biogeographic region of Australia's continental shelf and coastal waters. It includes the subtropical coastal waters of Southwest Australia.
The Spencer Gulf Shelf Province, also known as the South Australian Gulfs marine ecoregion, is a biogeographic region of Australia's continental shelf and coastal waters. It includes the warm temperate coastal waters of South Australia's central coast. It is a provincial bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system.
The Tasmanian Shelf Province is a biogeographic region of Tasmania's coastal and continental shelf waters. It covers the western, eastern, and southern coasts of Tasmania. It is a provincial level bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system. The Tasmanian Shelf and adjacent Bass Strait Shelf provinces correspond to the Bassian marine ecoregion in the WWF's Marine Ecoregions of the World system.
The Western Bass Strait Shelf Transition is a biogeographic region of Australia's coastal and continental shelf waters. It is a transitional region between the cold-temperate Bass Strait Shelf and Tasmanian Shelf provinces and the warm-temperate Spencer Gulf Shelf Province. It is a provincial bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system. It is the southern portion of the Western Bassian marine ecoregion in the World Wildlife Fund's (WWF) Marine Ecoregions of the World system.
Western Australia has the longest coastline of any state or territory in Australia, at 10,194 km or 12,889 km. It is a significant portion of the coastline of Australia, which is 35,877 km.
The Pilbara Coast is the coastline of Western Australia's Pilbara region. It is often referred to as the North West Coast of Western Australia.
The Dampier Marine Park is an Australian marine park offshore of Western Australia, north-east of Karratha. The marine park covers an area of 1,252 km2 (483 sq mi) and is assigned IUCN category VI. It is one of the 13 parks managed under the North-west Marine Parks Network.
The marine ecoregions of the South African exclusive economic zone are a set of geographically delineated regions of similar ecological characteristics on a fairly broad scale, covering the exclusive economic zone along the South African coast.
Cape Keraudren is a coastal headland on the northern coast of Western Australia.
The Bassian ecoregion is a biogeographic region of Australia's coastal and continental shelf waters. It includes the cold-temperate waters surrounding Tasmania, including the central Bass Strait between Tasmania and the southern Australian mainland. This ecoregion, designated in the Marine Ecoregions of the World system by the World Wildlife Fund (WWF), includes both the Bass Strait Shelf and Tasmanian Shelf provincial level bioregions from the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system.
