Late pleistocene paleotemperatures at tongue of the ocean, bahamas.

Estimates of paleotemperatures, based upon paleoecological analysis of planktonic foraminiferal thanatocoenoses of three piston cores from Tongue of the Ocean, Bahamas, indicate a maximum mean variation between Late Pleistocene glacial and nonglacial stages of 3.6 degrees C. The data also indicate that the Early Wisconsin glacial stage was 0.7 degrees C warmer than the Late Wisconsin glacial stage.
