Summary of sediment descriptions of ARA Islas Orcadas Cruise 16 piston cores

The primary goals of the coring program aboard cruise 16-78 of ARA Islas Orcadas were to survey older (pre-Pliocene) sediments of the Maurice Ewing Bank, the Georgia Basin, and the Islas Orcadas Rise and to trace the flow of antarctic deep water in the southwest Atlantic Ocean between the Mid-Atlantic Ridge and the America-Antarctic Ridge (Wise et al. 1978). A total of 69 piston cores were recovered, of which 68 were received at the Antarctic Research Facility.
