Planktic Foraminifer Census Data from Northwind Ridge Cores PI-88-AR P3, PI-88-AR P7, and PI-88-AR P9, Arctic Ocean

U.S. Geological Survey Open-File Report 93-218
Version 1.0

By Kevin M. Foley and Richard Z. Poore


The U.S. Geological Survey recovered 9 piston cores from the Northwind Ridge in the Canada Basin of the Arctic Ocean from a cruise of the USCGC Polar Star during 1988. Locations of these core sites are given in table 1 and shown in figures 1 and 2. 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 one million years. This report includes quantitative data on foraminifers and selected sediment size-fraction data in 98 samples from Northwind Ridge core PI-88AR P3, 51 samples from core PI-88-AR P7 and 117 samples from core PI-88-AR P9. These foraminifer data will be the basis for future interpretive studies.
