Lake Macleod and Sun Glint Highlighting Shores of Shark Bay, Australia

Australia – December 1st, 2012

Sun glint highlights the shoreline of Shark Bay, Peron Peninsula and Dirk Hartog Island in Western Australia. The bay itself covers an area of 10,000 km², with an average depth of 10 metres. It is divided by shallow banks and has many peninsulas and islands. The coastline is over 1,500 km long, and there are about 300 km of limestone cliffs overlooking the bay.

Visible to the north, not far inland from the coast, is Lake Macleod, the westernmost lake in Australia. A cool offshore current, coupled with a very flat coastal plain, contributes to the near-desert-like conditions along the coastal region as evidenced by the brown landscape around the lake and the highly reflective salt beds within the lake.

The Shark Bay World Heritage area is a series of gulfs, inlets, islands and bays and is split in two by the Peron Peninsula on Australias Coral Coast. The greenish color of the waters on either side of the peninsula is due to a mixture of sediments and algae.

Shark Bay World Heritage Area includes the nature reserves of Dirk Hartog, Bernier and Dorre islands and protects a 55% marine and 45% land environment.

Australia - September 5th, 2010

Most of the western part of Australia appears rusty red in color and quite arid, although the presence of vegetation increases as one moves southwards.

Notable features along the western coastline include the Shark Bay World Heritage Site. It is located below the center of the shoreline and contains several peninsulas and islands, the largest of which are Peron Peninsula (east) and Dirk Hartog Island (west).

The bay itself, in which some greenish algae or sediments can be seen, covers an area of 10,000 km², with an average depth of 10 metres.

The long, narrow peninsula situated between the Australia mainland (right) and Dirk Hartog Island (left) is called Peron Peninsula. It is part of the Shark Bay World Heritage Site in Western Australia. The water around the peninsula appears green in color due to a combination of algae and sediments.

The peninsula is some 80 miles (130 km) long, running north-northwesterly, east of Henri Freycinet Harbour and west of Havre Hamelin and Faure Island. It is the largest of the Shark Bay peninsulas.

The northern area contains the Francois Peron National Park. It is surrounded by the Shark Bay Marine Park and its lower southeast part is adjacent to the Hamelin Pool Marine Nature Reserve.

The narrowest section of the peninsula is between Nanga and Goulet Bluff, which has Shell Beach located on the eastern side that lies in the L’Haridon Bight.

Shark Bay, in the upper left quadrant, is a world heritage site in the Gascoyne region of Western Australia. It is located over 800 kilometres north of Perth, on the westernmost point of Australia.

The bay itself covers an area of 10,000 km², with an average depth of 10 metres. It is divided by shallow banks and has many peninsulas and islands. The coastline is over 1,500 km long.

It is located in the transition zone between three major climatic regions and between two major botanical provinces.

Shark Bay was inscribed as a World Heritage Site in 1991. The site covers an area of 23,000 square kilometres. It includes many protected areas and conservation reserves, including Shark Bay Marine Park, Francois Peron National Park, Hamelin Pool Marine Nature Reserve, Zuytdorp Nature Reserve and numerous protected islands.

Dirk Hartog Island (far left) is of major historic significance due to early explorers landing upon it.

Bernier and Dorre islands in the north west corner of the Heritage area are locations of some last remaining habitats of some Australian mammals threatened with extinction.

Shark Bay is an area of major zoological importance. The area supports 26 threatened Australian mammal species, over 230 species of bird, and nearly 150 species of reptile.

Shark Bay is home to about 10,000 dugongs (sea cows), and there are many dolphins, particularly at Monkey Mia.

It is an important breeding and nursery ground for fish, crustaceans, and coelenterates. There are 323 fish species, with many sharks and rays.

Shark Bay has the largest known area of seagrass, with seagrass meadows covering over 4000 km² of the bay. It includes the 1030 km² Wooramel Seagrass Bank, the largest seagrass bank in the world.

Shark Bay also contains the largest number of seagrass species ever recorded in one place; twelve species have been found, with up to nine occurring together in some places.
