Controls on the distribution of deep-sea sediments
We show that the parameters controlling the distribution of global seafloor sediments differ from the traditional view that sedimentation is primarily controlled by planktonic biological productivity [McCoy and Sancetta, 1985]. Our analysis provides constraints for the oceanographic conditions under which deep-sea sediments formed, at …
