Abstract

The detailed palaeomagnetic study of core 85027016, collected in central Baffin Bay, confirms the occurrence of anomalous directions in the depositional remanent magnetization, previously observed in the upper part of the Pleistocene sequence. Chronology and sedimentation rates are discussed on the basis of new 14C ages, 18O isotopic stratigraphy, and palaeoclimatic arguments provided by other works. Two successions of anomalous inclinations are recorded between 15 000 and 30 000 years BP, preceded by long-period secular variations. The possible occurrence of geomagnetic excursions in this region is discussed in considering contemporaneous high-resolution palaeomagnetic records of the Northern Hemisphere.
