The Caribbean Sea is a large tropical sea in the western Atlantic Ocean, southeast of the Gulf of Mexico, surrounded by the coasts of Central and South America and the islands of the Greater and Lesser Antilles. In this article, we are going to cover the Caribbean Sea, its boundaries and islands, climate and significance.
Caribbean Sea
The Caribbean Sea is one of the largest tropical seas in the world, situated in the western Atlantic Ocean, spreading between latitudes 9° and 22° N and longitudes 89° and 60° W. It covers an area of nearly 2,753,000 square kilometers, making it a vital part of the Earth’s marine geography.
- Southern boundary: Venezuela, Colombia, and Panama.
- Western boundary: Costa Rica, Nicaragua, Honduras, Guatemala, Belize, and Mexico’s Yucatán Peninsula.
- Northern boundary: The Greater Antilles, which include Cuba, Hispaniola (Haiti and the Dominican Republic), Jamaica, and Puerto Rico.
- Eastern boundary: The Lesser Antilles, a chain of smaller islands stretching from the Virgin Islands down to Trinidad and Tobago.
Among these, Jamaica, situated south of Cuba, is the largest island in the Caribbean.
The Caribbean Sea, along with the Gulf of Mexico, is sometimes also called the American Mediterranean, since both are enclosed between major landmasses. However, they differ greatly in their climate, currents, and water characteristics. The Cayman Trench, the deepest part of the Caribbean, plunges to about 7,686 meters below sea level, making it a significant geological feature.
