Underwater Sights and Wonders

Credit for this information and the photos goes to Wikipedia.  Many lists have been made of modern day wonders.

The Seven Underwater Wonders of the World was a list drawn up by CEDAM International, an American-based non-profit group for divers, dedicated to ocean preservation and research.

In 1989 CEDAM brought together a panel of marine scientists, including Dr. Eugenie Clark, to pick underwater areas which they considered to be worthy of protection. The results were announced at The National Aquarium in Washington DC by actor Lloyd Bridges, who played in a TV show titled Sea Hunt:

Palau

Palau, officially the Republic of Palau, is an island nation in the Pacific Ocean, some 500 miles east of the Philippines and 2,000 miles south of Tokyo.
It recently became known to the world through the television show, Survivor.
Palau’s most populous islands are Angaur, Babeldaob, Koror, and Peleliu. The latter three lie together within the same barrier reef, while Angaur is an oceanic island several miles to the south. About two-thirds of the population live on Koror. The coral atoll of Kayangel is situated north of these islands, while the uninhabited Rock Islands (about 200) are situated to the west of the main island group. A remote group of six islands, known as the Southwest Islands, some 375 miles from the main islands, are also part of the country and make up the states of Hatohobei and Sonsorol.

Belize Barrier Reef

The Belize Barrier Reef is a series of coral reefs straddling the coast of Belize, roughly 1,000 ft offshore in the north and 25 miles in the south within the country limits. The Belize Barrier Reef is a 186 mile long section of the 560 mile long Mesoamerican Barrier Reef System, which is continuous from Cancún on the northeast tip of the Yucatán Peninsula through the Riviera Maya up to Honduras, making it the second largest coral reef system in the world after the Great Barrier Reef in Australia, popular for scuba diving and snorkeling.

Great Barrier Reef

The Great Barrier Reef is the world’s largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 1,600 miles over an area of approximately 133,000 square miles. The reef is located in the Coral Sea, off the coast of Queensland in northeast Australia.

The Great Barrier Reef can be seen from outer space and is the world’s biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps.

Deep-Sea Hydrothermal Vents

A hydrothermal vent is a fissure in a planet’s surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots.

Hydrothermal vents in the deep ocean typically form along the Mid-ocean ridges, such as the East Pacific Rise and the Mid-Atlantic Ridge. These are locations where two tectonic plates are diverging and new crust is being formed.

The water that issues from seafloor hydrothermal vents consists mostly of sea water drawn into the hydrothermal system close to the volcanic edifice through faults and porous sediments or volcanic strata, plus some magmatic water released by the upwelling magma.

Galápagos Islands

The Galápagos Islands (official name: Archipiélago de Colón) are an archipelago of volcanic islands distributed around the equator in the Pacific Ocean, 972 km west of continental Ecuador. It is a UNESCO World Heritage site: wildlife is its most notable feature.

The Galápagos islands and its surrounding waters are part of a province, a national park, and a biological marine reserve.
The group consists of 15 main islands, 3 smaller islands, and 107 rocks and islets. The islands are located at the Galapagos Triple Junction. It is also atop the Galapagos hotspot, a place where the Earth’s crust is being melted from below by a mantle plume, creating volcanoes

Lake Baikal

Lake Baikal is the world’s second most voluminous lake, after the Caspian Sea. It is the most voluminous freshwater lake in the world with an average depth of 2,442 ft and contains a total of roughly 20 percent of the world’s surface fresh water. Located in the south of the Russian region of Siberia (between Irkutsk Oblast to the northwest and the Buryat Republic to the southeast, near the city of Irkutsk), the body of water is also known as the “Pearl of Siberia”.

At 5,390 ft Lake Baikal is the deepest, and among the clearest of all lakes in the world.

Northern Red Sea

The Northern Red Sea region of Eritrea is one of the country’s six regions. It lies along the northern three quarters of the Red Sea, and includes the Dahlak Archipelago and the coastal city of Massawa. The region borders the Anseba, Central and Southern regions to the west, and the Southern Red Sea region to the east. It has an area of around 27,800 km². The lowest point in Eritrea, Lake Kulul, is in this region.
The Red Sea is a seawater inlet of the Indian Ocean, lying between Africa and Asia. The connection to the ocean is in the south through the Bab el Mandeb strait and the Gulf of Aden. In the north, there is the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez (leading to the Suez Canal).
Occupying a part of the Great Rift Valley, the Red Sea has a surface area of roughly 169,100 square miles. It is about 1398 miles long and, at its widest point, is 220.6 miles wide. It has a maximum depth of 7254 feet in the central median trench, and an average depth of 1,608 feet. However, there are also extensive shallow shelves, noted for their marine life and corals. The sea is the habitat of over 1,000 invertebrate species, and 200 soft and hard corals. It is the world’s northernmost tropical sea.
