6 Ocean Landscapes That Are Simply Unique In The World

When people mention the word 'ocean' many think of the endless blue that touches the sky on the horizon. However, oceanic expanses are not so monotonous. In addition to the usual islands, peninsulas and coral reefs that we used to see at the ocean expanses, there are some ocean landscapes that are simply unique in the world.

# Meeting Place of the Atlantic Ocean and Caribbean Sea at Eleuthera Island, Bahamas

Eleuthera is one of several islands that lies within the archipelago in The Bahamas, about 80km (50mi) east of the capital city Nassau. It is long – about 180km (112mi) – and thin - only about 1.6 km (1mi) wide in places. The light blue waters of the shallow Caribbean Sea on one side of the island stand out in stark contrast to the deep blue of the Atlantic Ocean thousands of feet in depth. One of the best places to see this extraordinary juxtaposition is at the Glass Window Bridge.

# Meeting Place of the Baltic and North Sea, Denmark/Sweden

In the resort town of Skagen you can watch an amazing natural phenomenon. This city is the northernmost point of Denmark, where the Baltic and North Seas meet. The two opposing tides in this place can not merge because they have different densities. The area where the Baltic and the North Sea come into contact is quite shallow and so the contact face is relatively small. There is of course some mixing but it is quite minimal due to the difference of the density.

# Horizontal Falls, Australia

The Horizontal Falls or Horizontal Waterfalls (nicknamed the "Horries") is the name given to a natural phenomenon on the coast of the Kimberley region in Western Australia. Despite their name, the Horizontal Falls are a fast-moving tidal flow through two narrow, closely aligned gorges of the McLarty Range, located in Talbot Bay. The direction of the flow reverses with each change of tide. As tides in the Kimberley can reach 10 metres (33 ft), a peak tide gives rise to a significant difference in the sea level on either side of each gorge.

# The Deep Channel at the Great Barrier Reef, Australia

The Great Barrier Reef is the world's largest coral reef system. It is composed of nearly 3,000 individual reefs and 920 islands stretching for over 2,650kilometres (1,620mi) over an area of approximately 345,000 square kilometres (133,100sqmi). The reef is located in the Coral Sea, off the coast of Queensland, Australia. The Great Barrier Reef is the world's biggest single structure made by living organisms and can be seen from outer space. The reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports an incredible diversity of life and was declared a World Heritage Site in 1981. It is one of the seven natural wonders of the world.

# Underwater Waterfall, Mauritius

Mauritius is an island nation officially called the Republic of Mauritius, or in French, République de Maurice, located in the Indian Ocean about 2,000 km (1,240mi) off the southeast coast of the African continent. A fascinating illusion can be found at the Southwestern tip of the island. When seen from the air, a runoff of sand and silt deposits makes the illusion of an underwater waterfall. The visually deceiving impression is absolutely breathtaking when seen from aerial shots. In fact, the illusion can even be seen on Google Maps.

# The Great Blue Hole, Belize

The Great Blue Hole is a large submarine sinkhole off the coast of Belize. It lies near the center of Lighthouse Reef, a small atoll 70 km (43 mi) from the mainland and Belize City. The hole is circular in shape, over 300 m (984 ft) across and 124 m (407 ft) deep. The Great Blue Hole is a part of the larger Belize Barrier Reef Reserve System, a World Heritage Site of the United Nations Educational, Scientific and Cultural Organization (UNESCO).
