Palaeoclimatology and Palaeoceanography from Laminated Sediments (Geological Society Special Publication Ser. ; No. 116)

Concerned with laminated sediments of marine or lacustrine origin. Laminated sediments are unique in providing annual or sub-annual resolution, often recording individual depositional events. The book acts as a focus for results of current studies ranging from the Black Sea to the deep sea laminations of the equatorial Pacific. This volume will be of interest to geologists, sedimentologists, oceanographers and all who are concerned with climate change.

The separation of anthropogenically driven change from natural 'baseline' variability within the atmosphere/ocean system is a prerequisite to identifying human impact on global climate. An understanding of past climate variability is therefore a key to predicting future climate change. The sedimentary record of the oceans, seas and lakes is produced by a series of depositional events that occur on seasonal timescales but can rarely be resolved due to mixing of the sediment by bottomdwelling organisms. Where they are preserved, laminated sediments act like tree rings to record these seasonal-scale processes, such as plankton blooms and floods, and provide a uniquely high-resolution record of environmental change. In addition, annually laminated or 'varved' sediment sequences act as geochronometers against which other timescales can be tested. Laminated sediments may therefore be used to develop records of interannual and decadal-scale variability which serve to test models of climate change. The authors cover a range of topics that include strategies for study and techniques of analysis. A series of case studies, dealing with a variety of lacustrine and marine records, illustrates the wide potential of laminated sediments as palaeoclimatic and palaeoceanographic indicators Concerned with laminated sediments of marine or lacustrine origin.

Understanding the 'tipping points' that have lead to rapid changes in the Earth's climate is vitally important with the realization that humans modify global climate. In an effort to better understand past and future climate change, general circulation models have become the forerunners of attempts to simulate future climate. Although extraordinarily sophisticated, they remain imperfect tools that require 'grounding' in geological data. In this, the study of past major climate transitions like the Palaeozoic icehouse worlds and the extreme greenhouse of the Cretaceous are invaluable. Both the mechanisms that forced changes in the Earth's climate as well as the proxies that track these changes are discussed. The central message of the book is that general circulation models tested with geological data in an iterative 'ground truth' process provide the best estimates of the Earth's ancient climate.
