Lihou Reef National Nature Reserve is a 8,440 km² marine reserve in Australia in the Coral Sea . The eponymous atoll Lihou Reef should not be confused with the island of Lihou . It is located off the east coast of Australia about 700 km from Cairns in Queensland . Together with the Coringa-Herald National Nature Reserve 100 km away , it forms the larger Coral Sea Reserves Ramsar Site with an area of 17,290 km, which was established on August 16, 2002. It is a wetland of international importance according to the Ramsar Convention and one of the largest lagoons in the world.
history
Now known as Lihou Reef and Cays , the atoll was discovered by Lieutenant John Lihou of the Royal Navy on February 23, 1823. Lihou, who was a ship master on the brig HMS Zenobia , was en route from Manila to South America . After a dangerous passage through the Great Barrier Reef , it left this through an opening in the Murray Islands . On the further journey through the Coral Sea , the atoll Lihou Reef and Cays , 1155 km as the crow flies from the Murray Islands, was sighted.
geography
The Lihou Reef is the second largest atoll in the Coral Sea , according to to New Caledonia belonging Chesterfield Islands (here the even larger submarine is Lansdowne Bank not included). It is U-shaped, with an opening in the southwest. The size of the lagoon measures 100 by 30 km, with an area of 2,529 km², and makes this atoll one of the largest in the world, although the total land area of all islands on the fringing reef ( Cays ) is barely more than one square kilometer. The lagoon is about 60 m deep. The marine reserve includes 18 cays, 9 each in the Northern Rim and 9 in the Southern Rim , ranging in size from 0.5 to 16.8 hectares .
