Paleointensity records from marine sediments at three locations in the Atlantic, Indian, and Pacific oceans show coherent and reproducible signals across the Brunhes-Matuyama reversal. The low-field susceptibility signals are predominantly anticorrelated between the Indo-Pacific and the Atlantic sites while the normalization of the natural remanent magnetization by any rock magnetic parameter yield identical results. We deduce that in these cases climatic components do not induce first order effects in the determination of relative paleointensity. The results establish the worldwide character of the triangular pattern displayed by the decay and recovery phases of the field intensity variations across the Brunhes-Matuyama reversal. |
