Correlating high-frequency climate variations

There has been a great deal of recent interest in correlating high sedimentation rate marine sequences to high frequency climate fluctuations from the Greenland ice cores. However, conclusions about physical connections between far-field records and the Greenland cores are often based on subjective comparisons. The possibility that high-resolution marine records could be influenced by bioturbation and/or stochastic pubes in sedimentation is also sometimes insufficiently addressed. It is suggested that a protocol be established for a mote formal approach to correlating high-frequency events, with the software being made widely available to the research community. Such an approach should enable the climate community to more objectively assess claims concerning physical linkages between different regions.
