Earth science: Sediment en route to oblivion
Philip A. Allen1
Abstract
Sudden collapses of the sea floor can generate oceanic sediment flows that dwarf the global annual sediment input from rivers. Such flows can travel great distances, and undergo transformation along the way.
The seabed of the oceans is prone to failure, generating high-density sediment flows of immense volume that can run for hundreds to thousands of kilometres from the continental margin to the deep oceanic plains. On page 541 of this issue, Talling and co-workers1 report on one such flow, which occurred about 60,000 years ago off northwest Africa.
