The Thermosphere is located between 80 and 400 km above the mesopause. It contains electrically charged particles known as ions. It is therefore known as Ionosphere. The temperature here starts increasing with heights. Radio waves transmitted from the earth are reflected back to the earth by this layer. The International Space Station and other satellites orbit in this layer. Auroras are observed in the lower parts of this layer.
The Gulf of Guinea is the northeastern most part of the tropical Atlantic Ocean. In this Gulf, there happens the intersection of the Equator and the Prime Meridian (zero degree latitude and longitude).
