introduccionIntroduction

The Coral Sea is a marginal sea of the South Pacific off the north eastern coast of Australia, and is classified as an interim Australian bioregion. The Coral Sea extends 2,000 miles along the north eastern Australian coast.

It borders on the west with the east coast of Queensland, thereby including the Great Barrier Reef; In the east, Vanuatu and new Caledonia; And, in the northeast, by the southern end of the Solomon Islands. In the northwest, it reaches the south coast of new Guinea including the Gulf of Papua. It melts with the Tasmanian sea in the south, with the Sea of Solomon in the north and with the Pacific Ocean in the east. In the West, it is limited by the mainland coast of Queensland, and in the northwest, it connects with the Arafura Sea through the Strait of towers.

The sea is characterized by its warm and stable climate, with frequent rains and tropical cyclones. It contains numerous islands and reefs, as well as the world's largest reef system, the great Coral Barrier, which was declared a World Heritage Site by UNESCO in 1981.

geologiaGeology

The Coral Sea basin was formed between 58 million and 48 million years ago when the Queensland continental shelf rose as the continental blocs sank at the same time. The sea has been an important source of coral for the Great Barrier Reef, both during its formation and after lowering the sea level.

The processes of geological formation are still happening today, as evidenced in part by seismic activity. Several hundred earthquakes with the magnitude between 2 and 6 were recorded in the period 1866-2000 along the Queensland coast and in the Coral sea itself.

The sea received its name due to its numerous choral formations. It includes the Great Barrier Reef, which stretches about 2,000 km along the north eastern coast of Australia and also includes approximately 2,900 individual reefs and 1,000 islands.

hidrologiaHidrology

The main currents of the Coral sea turn counter-clockwise, including the Australian current of the east. It brings warm, low-nutrient waters from the Coral Sea along the east coast of Australia to the fresh waters of the Tasmanian Sea. This current is the strongest along the Australian coast and carries 30 million m3/s of water within a flow band of about 100 kilometres wide and 500 meters deep. The current is stronger around February and weaker around August.

The main river that flows into the sea is the Burdekin River, which has its south eastern delta of Townsville. Due to seasonal and annual variations in cyclone succession and precipitation (typically between 200 and 1600 mm/year), their annual discharge may vary more than 10 times in two consecutive years. This irregularity gives rise to fluctuations in the composition of seawater near the delta of the river.

The surface water temperature varies in the south of the sea from 19 ° C in August to 24 °C in February. It is quite warm and stable at 27 – 28 ° С in the north all year round. The salinity of the water is 34,5-35,5 ‰ (parts per mil). The water is mostly very clear, with the visibility of about 30 meters near the reefs.

climaClimate

The sea has a subtropical climate and is frequently hit by tropical cyclones, especially between January and April. The cyclonic frequency decreased from 1997 to 2005 to 1.5 cyclones per year (12 in total).

Annual rainfall varies between 1,000 and 3,000 mm depending on the area. Most rains fall between December and March, in the form of intense showers lasting 30 – 60 days. The number of clear days per year varies approximately between 80 and 125, and the typical temperature variation throughout the year is 18 – 27 °C.

The Australian coast of the Coral Sea is mostly made up of sand. The Great Barrier Reef is too far away to provide significant coral deposits, but it effectively provides a screen against ocean waves. As a result, most of the Earth's vegetation extends under the sea, and coastal waters are rich in underwater vegetation, such as green algae.

The islands of the Great Barrier Reef contain more than 2,000 species of plants, and three of them are endemic. The northern islands have 300 to 350 species of plants that tend to be woody, while the southern islands have 200 that are more herbaceous; The region of Whitsunday is the most diverse, has 1,141 species. The plants are scattered by the birds.

Además de su interés científico, el arrecife se ha vuelto cada vez más importante como atracción turística. La creciente preocupación por la preservación de su patrimonio natural ha llevado a un mayor control de las actividades potencialmente amenazadoras como la perforación de recursos petrolíferos. El uso extensivo de las embarcaciones turísticas y la sostenibilidad de la pesca comercial fueron cuestiones controvertidas a finales del siglo XX.

The sea hosts numerous species of anemones, sponges, worms, gastropods, lobsters, prawns and crabs. Algae such as Lithothamnion and Porolithon dye purple many coral reefs and Halimeda green algae is found all over the sea. The coastal plants consist of only 30 to 40 species, and the mangroves are in the northern part of the sea.

It has about 400 species of corals both hard and soft, which belong to 36 genera. We also have living in reefs more than 1,500 species of fish and 500 species of algae, including thirteen species of the genus Halimeda.

The Crown of Thorns Sea Star (Acanthaster Planci) is the main predator of the reefs, as it preys on the coral polyps clambering over them, taking out their stomachs, and releasing digestive enzymes to absorb the liquefied tissue. An adult individual can eat up to 6 m2 of reef per year.

There are at least 30 species of whales, dolphins and porpoises, including the hunchbacked Indo-Pacific Dolphin, the humpback whale and the dugongs. Six species of sea turtles breed in the Great Barrier Reef.

More than 200 species of birds (including 22 species of seabirds and 32 species of terrestrial birds) visit, nest, or perch on the islands and reefs, including the White-bellied Sea eagle and the spatula. Most nesting sites are located on the islands of the North and South regions of the Great Barrier Reef, with between 1.4 and 1.7 million of birds using the sites to breed.

Seventeen species of sea serpents, including Laticauda Colubrina, live in the Great Barrier Reef in warm waters up to 50 meters deep and are more common in the South than in the northern section. None of them are endemic or in danger of extinction. The venom of many of these snakes is highly toxic; For example, Aipysurus duboisii is considered to be the most poisonous sea serpent in the world.

There are more than 1,500 species of fish, including the Clown (fish), the red bass (Lutjanus Bohar), the Red-throated Emperor (Lethrinus miniatus), the Coral Trout (Plectropomus leopardus) and several species of snapper (Lutjanidae). 49 species spawn in mass and 84 other species spawn in other places at their fingertips. With a maximum total length of 0.84 cm, Schindleria Brevipinguis, who is originally from the Great Barrier Reef, is one of the smallest fish and vertebrate known.

Salt water crocodiles live in mangrove swamps and salt flats on the coast. Around 125 species of sharks, rays, skates or Chimaera live in the Great Barrier Reef, as well as about 5,000 species of molluscs. The latter include the giant clam and several nudibranchs.

A study of 443 individual sharks gives the following distribution of their species on the Australian side of the Coral Sea: Reef-grey shark (Amblyrhynchos shark, 69%), white-tipped reef shark (Triaenodon obeso, 21%), Puntal shark Silver (Carcharhinus albimarginatus, 10%), Tiger shark (Galeocerdo Cuvier, < 1%) and Great hammerhead shark (Sphyrna mokarran, < 1%).
