Key Facts about Gulf of Guinea

About Gulf of Guinea:

  • It is the northeasternmost portion of the tropical Atlantic Ocean, located off the western coast of the African continent.
  • It is found at the junction of the Prime Meridian and the Equator at 0°0’N and 0°0’E. 
  • The area covers 2.3 million square kilometers, with approximately 6,000 kilometers of coastline.
  • It has a narrow continental shelf.
  • It has warm tropical waters with relatively low salinity because of the rivers that drain into it and also due to the high rainfall in the region.
  • Its major tributaries are the Volta and Niger rivers.
  • Coastline:
    • The 16 coastal countries that are situated along the Gulf of Guinea are Angola, Benin, Cameroon, Cote d’Ivoire, Democratic Republic of Congo, Republic of Congo, Guinea, Equatorial Guinea, Guinea-Bissau, Gabon, Nigeria, Ghana, São Tomé and Principe, Togo, and Sierra Leone.
    • The coastal region of the Gulf is mostly low-lying and is interspersed with mangrove swamps, marshes, and lagoons.
    • The coastline of the Gulf of Guinea is remarkably similar to the continental margin of South America (that runs from Brazil to the Guianas), thus establishing a clear confirmation of the theory of continental drift.
  • The Gulf of Guinea region accounts for more than 35% of the world’s total petroleum reserves.
  • It is one of the world’s most dangerous gulfs because of the widespread piracy that has severely affected many countries in West Africa, along with other international countries.

Q1) What is continental shelf?

A continental shelf is the edge of a continent lying beneath the ocean. This shelf extends from the coastline of a continent to a drop off point called the shelf break. The shelf break is where the underwater edge of a continent shelf begins to rapidly slope downwards towards the ocean floor depths. From the break, the shelf descends into the deep ocean floor in the form of a continental slope.
