Abstract
SEDIMENT cores were obtained from the Iberia Abyssal Plain and the Biscay Abyssal Plain1 on a cruise of R.R.S. Discovery II in 1958 organized by the Department of Geodesy and Geophysics of the University of Cambridge. These cores consist of beds of sediment deposited by turbidity currents, which are sometimes only a few cm thick but are more often 50–100 cm thick, and alternating with these beds is normal pelagic sediment, not thicker than about 40 cm. These cores have characteristics similar to those of abyssal plain sediments elsewhere described by Ericson and others2.
