Acquiring high to ultra-high resolution geological records of past climate change



Ultra-high resolution sedimentary records allow reconstruction of climate change on human time-scales. Such records, drilled by ICDP/ODP in a few areas, have contributed significantly to current understanding of the climate system. The workshop will bring together experts to identify a global array of coring sites of high- to ultra-high-resolution sedimentary records to fully understand the ocean-continent-atmosphere system and test the findings of the IPCC Report using Multi-Platform Drilling.

The study of sedimentary records with high to ultra high temporal resolution approaching those of instrumental records (e.g. varved muds, muds rich in tephra layers, muds with excellent magnetic signals, dust, corals with growth bands) has a high potential to achieve several highly ranked scientific goals of the ICDP and IODP Initial Science Plans, including palaeoclimatic/ palaeoenvironmental reconstructions, the relative importance of anthropogenic versus natural forces in controlling climatic and environmental change, evolution and extinction of species, and well-being of humans in general. These records, ideally with a sub-annual to centennial resolution, provide a unique opportunity to evaluate the operation of the ocean-continent-atmosphere system globally, and on human time scales, and to appraise the relative importance of each part of the system. Their understanding is "an essential component of responsible management strategies for the resources and environment of the dynamic Earth" (cit. ICDP). Furthermore, determining environmental boundary conditions, primary causative mechanism, and operative feedbacks of climate variability in the geologic past represents an important component for testing predictions of future climate change as outlined in the Intergovernmental Panel on Climate Change (IPCC) Report.

Long records of excellent quality have been drilled through ocean drilling and contributed significantly to our current understanding of the climate system (e.g. ODP Drilling in the Santa Barbara Basin, California). Equally, lacustrine records of comparable resolution have significantly enhanced the climate "portfolio". When calibrated independently with C-14 dating, or when long-floating time scales can be constructed, varve time scales proved to be robust and suitable for large-scale correlation. Having such detailed multi-proxy records of past marine and continental environmental conditions available will allow researchers to better understand why and how the whole climate system responds rapidly to external and internal forcing and how the various oscillations of the climate system may interact over much longer time intervals.
