Possible Effects of Orbital Variations on Past Sources and Transports of Eolian Material: Estimates from General Circulation Model Experiments

Part of the NATO ASI Series book series (ASIC, volume 282)

Abstract

Paleoclimate simulation experiments for various orbital configurations of precession, tilt and eccentricity (for 9000 and 125,000 years ago) and for glacial-age boundary conditions (for 18,000 years ago) provide examples of possible variations in sources/sinks and transports of eolian material. These types of experiments are likely to play an increasingly important role in helping to interpret the eolian sediment record.
