Formatted Abstract/Summary
A high-resolution, multiproxy record of palaeoclimatic and palaeoenvironmental variability extending ca. 36 14C kyr has been reconstructed from lake sediment from North Stradbroke Island, Queensland, Australia. Aeolian sediment deposits (consisting of both local and far-traveled material) extracted from lake sediment act as a proxy for aridity and drought in eastern Australia. Particle size analysis of the sediments provides an indication of palaeowind strength, and pollen and charcoal analyses provide insight into palaeoenvironmental conditions, correlating well with the record of aeolian sedimentation. Using bioclimatic envelopes, specific temperature and precipitation values can be estimated based on species identified in the pollen record. The quantification of specific climate variables during past periods of increased aridity (e.g. the Last Glacial Maximum) is valuable for gaining insight into what we might expect under various future climate change scenarios.
