Abstrakt:
A distinct peak has been discovered in the ³⁶Cl data from the GRIP ice core between the Dansgaard Oeschger (D-O)
events 6 and 7 at approximately 32 kyr BP. This peak can be attributed to a minimum of the geomagnetic dipole field
associated with the Mono Lake event. Since the ³⁶Cl peak reflects a higher production rate of all cosmogenic
radionuclides, it has an impact on the ¹⁴C dating of the last ice age. Furthermore, it provides an additional time marker
similar to a peak found earlier corresponding to the Laschamp event at approximately 39 kyr BP.
