Caribbean Sea

The Caribbean Sea is a beautiful sea part of the North Atlantic Ocean in the warm tropics of the Western Hemisphere. It sits south of the Gulf of Mexico and southwest of the Sargasso Sea. All around it are many islands and lands, bounded by the Greater Antilles from Cuba to Puerto Rico, the Lesser Antilles from the Virgin Islands to Trinidad and Tobago, South America from Venezuela to Colombia, and Central America and the Yucatán Peninsula from Panama to Mexico.

This sea is one of the largest in the world, covering about 2,754,000 km². Its deepest spot is the Cayman Trough between the Cayman Islands and Jamaica, diving down more than 7,600 meters below sea level. The coastline is full of interesting features like gulfs and bays, such as the Gulf of Gonâve, the Gulf of Venezuela, and the Gulf of Honduras.

One amazing part of the Caribbean Sea is the world's second-largest barrier reef, called the Mesoamerican Barrier Reef. It stretches for over 1,000 kilometers along the shores of Mexico, Belize, Guatemala, and Honduras.

History

Main article: History of the Caribbean

The name Caribbean comes from the Caribs, one of the main native groups when Europeans first arrived in the late 1400s. After Christopher Columbus landed in The Bahamas in 1492 and found some of the islands, Europeans began calling the area the Sea of the Antilles.

From the 1500s onward, many European countries such as Spain, England, France, and others explored and settled the islands. The Caribbean Sea became an important place for trade and travel, and sometimes pirates would show up looking for treasure. Today, the area includes many island territories and borders several countries.

Extent

The International Hydrographic Organization defines the edges of the Caribbean Sea. To the north, it includes the Windward Channel, a line between Caleta Point in Cuba and Pearl Point in Haiti. To the east, it stretches from Point San Diego in Puerto Rico along the coast, including all the islands and waters of the Lesser Antilles, but stopping just before Trinidad.

Even though Trinidad and Tobago and Barbados sit on the same underwater land, they are considered part of the Atlantic Ocean, not the Caribbean Sea.

Geology

The Caribbean Sea sits on the Caribbean Plate and is surrounded by chains of islands called island arcs. These islands were formed when the South American Plate moved into the Caribbean Plate, creating active and extinct volcanoes like Mount Pelee and La Soufrière.

The Caribbean Sea formed around 160 to 180 million years ago when the ancient supercontinent Pangaea broke apart. Over time, the sea's shape changed, and today it has several deep basins separated by underwater ridges. The deepest part of the sea is the Cayman Trough, where the water can reach about 7,686 meters deep. The area can experience strong earthquakes, which sometimes cause tsunamis.

Oceanography

The Caribbean Sea has very similar water conditions all year round. The temperature only changes by about 3 °C (5.4 °F) between the coolest and warmest months. Over the past 50 years, the sea has gone through cooler times and warmer times, with changes linked to weather patterns like El Niño and La Niña. The saltiness of the water stays about the same at 3.6%, and it looks blue-green from above.

The deepest parts of the Caribbean Sea are similar to the deep parts of the Atlantic Ocean nearby. Water from the Atlantic flows into the Caribbean, and winds on the western side push water north, helping create rich fishing areas near Yucatán.

Ecology

The Caribbean Sea is home to many beautiful coral reefs, which are important habitats for sea life. These reefs support activities like fishing and scuba diving and are worth billions of dollars to the local economy. However, warm waters can harm the reefs, causing them to lose their color and become weak.

Sadly, pollution is also a big problem in the Caribbean Sea. Lots of garbage ends up in the water each year, which hurts the plants and animals that live there and can affect the jobs of people who depend on the sea for tourism and fishing.

Climate

The Caribbean Sea has a tropical climate because it is close to the equator and influenced by warm ocean currents. The main current is the North Equatorial Current, coming from the Atlantic. The weather varies from tropical rainforest in some places to tropical savanna in others. Some areas, like the ABC islands, stay dry because of cool ocean currents, while warm, moist trade winds bring rain to many regions.

Rainfall changes depending on the height of the land and the nearby water currents. Areas near the Caribbean Sea from Costa Rica to Belize, as well as the Dominican Republic and Puerto Rico, have rainy, tropical rainforest climates. Drier, seasonal climates are found in Cuba, northern Venezuela, Colombia, and southern Yucatán, Mexico. Very dry climates exist along the northern coasts of Venezuela and Colombia, including islands like Aruba and Curaçao.

The Caribbean can face strong storms called tropical cyclones. Though they don’t hit land often, they can cause damage when they do. These storms often start near the west coast of Africa and move across the Atlantic, or they can form in the Caribbean itself. The hurricane season lasts from June to November, with most storms happening in August and September. On average, about nine tropical storms develop each year, and five of these become hurricanes.

Flora and fauna

The Caribbean Sea is full of many different plants and animals, making it a place of high biodiversity. Many of these species are found only in this area, which means they are endemic.

The plants in the Caribbean are mostly tropical, with many different kinds growing because of changes in land shape, soil, and weather. About 13,000 types of plants grow here, and more than half of them are endemic. Some special plants include guaiac wood, which is the national flower of Jamaica, and the Bayahibe rose, the national flower of the Dominican Republic. In shallow water near coral reefs, you can find sea grasses like turtle grass and manatee grass.

The Caribbean Sea is also home to many animals. There are about 1,000 kinds of fish, such as sharks and parrotfish. The area has 90 types of mammals, including dolphins and whales. There are also many reptiles, like iguanas and sea turtles. Some of these animals are in danger, such as certain kinds of sea turtles and the blue iguana. Birds are also common here, with 600 different types recorded, including todies and frigatebirds.

Economy and human activity

The Caribbean region has grown busier with people and work since the time when new groups of people first arrived. The Caribbean Sea is a big place for getting oil, making around 170 million tons each year. It is also an important place for fishing, providing about 500,000 tonnes of fish yearly for nearby countries.

The area is well-known for making rum, with the first written record of it coming from Barbados around 1650. Tourism is very important here too. Each year, around 12 million visitors come to the Caribbean, with many enjoying activities like scuba diving and snorkeling on the beautiful coral reefs, which help the local economies grow.
