The Gulf of Guinea is located in the south-easternmost part of the North Atlantic Ocean and has an area of around 2.35 million km2. Its located in the intersection between Central and Western Africa and is bordered by Cape Lopez in Gabon and Cape Palmas in Liberia. The ocean inlet is home to several volcanic islands, including the nation of São Tomé and Príncipe. Many rivers flow into the Gulf of Guinea, with the most prominent ones being the Niger, the Volta and the Sanaga. Due to the large amount of organic sediments deposited by the Niger in the past millions of years, the region is now one of the world’s largest and most important oil extraction areas.
