These basins were formed nearly 100 million years ago, back when the South Atlantic was a narrow marine environment between South America and Africa. The region is characterised by extensive deep sedimentary environments and pockmark fields, where it is speculated that natural gas may be emitted from the seabed and potentially sustain chemosynthetic ecosystems. There are also steep rocky slopes that are home to important cold-water coral reef systems, irregularly threatened by fisheries activity. Many knowledge gaps exist in this region, and filling them is critical for responsible management of current and future human activities. false 10.
