Late Quaternary paleoclimatology and paleooceanography of the Labrador Sea and Baffin Bay: an alternative viewpoint
Previous interpretations of Labrador Sea and Baffin Bay sediment cores were hampered by failure to recognize that the presence of small (62–149 μm) specimens of ‘subpolar’ planktic foraminifera in high‐latitude marine sediments is primarily a function of the geochemistry of the water column and/or s...
