Gulf of Carpentaria

The Gulf of Carpentaria is a sea off the northern coast of Australia. It is enclosed on three sides by northern Australia and bounded on the north by the eastern Arafura Sea, which separates Australia and New Guinea. The northern boundary is generally defined as a line from Slade Point, Queensland (the northwestern corner of Cape York Peninsula) in the northeast, to Cape Arnhem on the Gove Peninsula, Northern Territory (the easternmost point of Arnhem Land), in the west.

At its mouth, the Gulf is 590 km (370 mi) wide, and further south, 675 km (420 mi). The north–south length exceeds 700 km (430 mi). It covers a water area of about 300,000 km2 (120,000 sq mi). The general depth is between 55 and 66 metres (30 and 36 fathoms) with a maximum depth of 69 metres (38 fathoms). The tidal range in the Gulf of Carpentaria is between two and three metres (6.5 and 10 ft). The Gulf and adjacent Sahul Shelf were dry land at the peak of the last ice age 18,000 years ago when global sea level was around 120 m (390 ft) below its present position. At that time a large, shallow lake occupied the centre of what is now the Gulf. The Gulf hosts a submerged coral reef province that was only recognised in 2004.

Yulluna (also known as Yalarnga, Yalarrnga, Jalanga, Jalannga, Wonganja, Gunggalida, Jokula) is an Australian Aboriginal language. The Yulluna language region includes the local government boundaries of the Shire of Cloncurry.

Kayardild (also known as Kaiadilt and Gayadilta) is a language of the Gulf of Carpentaria. The Kayardild language region includes the landscape within the local government boundaries of the Mornington Shire Council.

The first European explorer to visit the region (and Australia) was the Dutch Willem Janszoon (whose name is also written as Jansz) in his 1605–06 voyage. His fellow countryman, Jan Carstenszoon (or Carstensz), visited in 1623 and named the gulf in honour of Pieter de Carpentier, at that time the Governor-General of the Dutch East Indies. Abel Tasman also explored the coast in 1644. The region was later explored and charted by the English navigator Matthew Flinders in 1802 and 1803.

The first overland expedition to reach the Gulf was the Burke and Wills expedition, led by Robert O'Hara Burke and William John Wills which left Melbourne, Victoria in August 1860 and reached the mouth of the Bynoe River in February 1861. However, both men died on the return journey.

The land bordering the Gulf is generally flat and low-lying. To the west is Arnhem Land and Groote Eylandt, the largest island in the Gulf. To the east is the Cape York Peninsula and the Torres Strait which joins the Gulf to the Coral Sea. The area to the south (like the Cape York Peninsula, part of Queensland) is known as the Gulf Country.

The Gulf Country supports the world's largest intact savanna woodlands as well as native grasslands, known as the Carpentaria tropical savanna. The woodlands also extend up the west and east coast of the Gulf. They are dominated by Eucalyptus and Melaleuca species from the family Myrtaceae.
