Abstract

There is plenty of evidence on land that, from time to time, the Earth is hit by large extraterrestrial bodies. Not surprisingly, such impacts in the oceans leave little such evidence. But 30 years ago a site in the Southern Ocean was identified as a place where a bolide, known as the Eltanin meteorite, hit some 2.16 million years ago. A new survey, including the drilling of three cores at different depths, provides fresh data on the impact and its consequences: the impact left no crater on the sea floor, but it still could have been up to 4 kilometres in diameter.
