Claimed undersea impact crater in the Atlantic Ocean
Map and regional seismic sections showing location of Nadir Crater
The Nadir crater is an undersea feature on the Guinea Plateau in the Atlantic Ocean, 248 mi (400 km) off the coast of Guinea. It is suggested to be an impact crater. The feature is named after the Nadir Seamount, located 100 km to the south, and is around 8.5 km wide. The paper announcing the discovery of the feature was published in Science Advances in 2022.[1] It has been proposed that the structure be drilled to confirm/disprove the impact origin.[2]
