Properties of North Atlantic Abyssal Plain Sediments From High-Quality Long Piston Cores

Abstract

Two abyssal plain sites on either side of the North Atlantic Ocean are characterized by sequences of distal turbidites and pelagic clays. At the Great Meteor East location, turbidites are quite thick and geotechnical properties such as water content and shear strength can be correlated to the observed stratigraphy. At the Southern Nares Abyssal Plain site, turbidites are much thinner, harder to identify, and less distinct from the pelagic clays. Geotechnical properties there can not easily be correlated to the type of sediment.
