FAUNAL, SEDIMENTARY AND MAGNETIC INVESTIGATIONS OF ARCTIC OCEAN BOTTOM CORES.

Cores taken from ice-island T-3 in the Arctic Ocean do not reflect marked climatic changes. Correlation was attempted among four cores taken from a small region of the Alpha Cordillera. Correlation attempts are based on two horizons--the tops of the cores and the level of the Brunhes-Matuyama magnet...

Description
Summary:Cores taken from ice-island T-3 in the Arctic Ocean do not reflect marked climatic changes. Correlation was attempted among four cores taken from a small region of the Alpha Cordillera. Correlation attempts are based on two horizons--the tops of the cores and the level of the Brunhes-Matuyama magnetic boundary, found by using a spinner magnetometer. Correlation on the basis of plankton abundance and amounts of ice-rafted debris is unfeasible. The plankton abundance and amounts of ice-rafted material show no relationship, as they should if the Arctic fluctuated between warm open conditions and closed rigid conditions. The most significant data for correlation are obtained from the single planktonic foraminifer, Globigerina pachyderma. (Author)
