Lake Kivu, one of the African Great Lakes, sits along a tectonic plate boundary called the East African Rift, which is dotted with hot springs that feed carbon dioxide and methane into the water.

The lake’s geochemistry is unusual, largely as a consequence of local subaquatic springs that absorb carbon dioxide from the region’s volcanic soil and feed the gas into Kivu’s deepest waters.

Deep at the bottom of the lake, about 1,000 feet (300m) down, Kivu's water is heavy with dissolved gas. The lake contains an estimated 256 cubic kilometres of carbon dioxide (CO2) and 65 cubic ...
