Coral reefs around the islands are a paradise for diving and there are a variety of unique marine life.

Raja Ampat area is the island group, with one - the only means of transport that can be used by the Community about is the sea freight transportation. This transport is used both to reach the capital of the district Waisai or vice versa. With four main islands located in this area makes its own uniqueness.

This area is already known throughout the world for its natural beauty that is very charming. This region is also dubbed the Amazon region as a World Ocean. The nickname was given because of the location of these sites is in the center of world coral triangle. This region consists of many islands and narrow straits, resulting in most of the other dive destinations have a strong current, it is very exciting because the diver does not require much effort in doing this sport while looking beauty charm coral reefs and various types of fish is very beautiful.

Hardly exist anywhere else in the world that has the number of coral species that much in a natural area that can be said is not too broad. Even the spectacular news is around 10 times the number of coral species has ever been found throughout the Caribbean. Charm biodiversity Raja Ampat archipelago is indeed practically very abundant. Here you can find no less than about types of coral with decorated downstream mudiknya various types of right that many forms as well as body color colorful very beautiful, and you know, that would be to find about 1, species of fish in a single location is not too large.

Unknown September 11, at AM. The technical term for the difference in water level between high tide and low tide is tidal range. The flow and ebb are gradual, so it is not accurate to say that a high or low tide lasts around 6 hours and 12 minutes, i. The speed of the water flow varies during this period, and it also varies from place to place.

People who have to consider the tides in their daily life, like sailors, fishers, and surfers, often use what is called the rule of 12ths to calculate the expected water level. In the 1st hour, the tide would rise 1 foot. In the 2nd hour, it would rise 2 feet. In the 3rd and 4th hours, it would rise 3 feet. In the 5th hour, the tide would rise 2 feet, and in the 6th hour, 1 foot. The astronomical forces that drive the tides can be predicted very accurately, and these predictions are published in local tidal tables.

However, different weather conditions also affect the sea level and may cause both lower and higher tides than expected. If there is a storm, the seawater level often increases.

This is called a storm tide and is caused by a combination of storm surge and normal tidal movement. Strong offshore winds can move water away from coastlines, exaggerating the low tide. At the same time, onshore winds may cause the water to pile up onto the shoreline, making the low tide higher than usual.

High-pressure weather systems can lead to days with exceptionally low tides. In contrast, low-pressure systems may contribute to causing much higher tides than predicted.

The average tidal range in mid-ocean is around 1 meter or 3 feet. However, in some coastal areas, the tidal range can be more than 10 times higher in the most extreme regions. To give an average for tidal range along the world's coastlines doesn't make much sense, as they vary so much from place to place.

The environmental impact of tidal lagoons is minimal. The lagoons can be constructed with natural materials like rock. They would appear as a low breakwater sea wall at low tide, and be submerge d at high tide.

Animals could swim around the structure, and smaller organisms could swim inside it. Large predator s like sharks would not be able to penetrate the lagoon, so smaller fish would probably thrive. Birds would likely flock to the area. But the energy output from generators using tidal lagoons is likely to be low. There are no functioning examples yet. China is constructing a tidal lagoon power plant at the Yalu River, near its border with North Korea. A private company is also planning a small tidal lagoon power plant in Swansea Bay, Wales.

Using DTP, enormous dams as long as 50 kilometers 31 miles would extend straight from the shore into the open ocean. Often used as a source of hydroelectric power.
