The U.S. Geological Survey recovered 9 piston cores from the Northwind Ridge in the Canada Basin of the Arctic Ocean from the USCGC Polar Star during 1988 and 1989. Preliminary analysis of the cores suggests sediments deposited on Northwind Ridge preserve a detailed record of glacial and interglacial cycles for the last few hundred thousand to million years. This report includes quantitative data on planktic foraminifers and selected sediment size-fraction data in 130 samples from the Northwind Ridge Core 5. These foraminifer data will be the basis for future interpretive studies.
This work was funded by the U.S. Geological Survey Global Change and Climate History Program and the U.S. Department of Energy (Agreement No. DE-AI21-83MC20422).
