A total of 661 lake/wetland, geomorphic, marine, and speleothem records were identified and then assessed against a set of a priori criteria based on temporal resolution, record length, dating methods, and confidence of the proxy-climate relationship over the Common Era. A high quality subset of 22 records across Australasia met the criteria and they are endorsed for subsequent analyses. New chronologies based on progressive Bayesian techniques were constructed for the high quality records to ensure a consistent approach to age modelling and quantification of age uncertainties. Chronological uncertainty was the primary reason why records did not meet the selection criteria. Despite present limitations, existing proxies and reconstruction techniques that successfully capture climate variability in the region show potential to address spatial gaps and expand the range of climate variables covering the last 2000 years from the Australasian region. #--------------------------------------- # Publication # Authors: Marx, SK; McGowan, HA; Kamber; BS # Published_Date_or_Year: 2009 # Published_Title: Long-range dust transport from eastern Australia: A proxy for Holocene aridity and ENSO-type climate variability # Journal_Name: Earth and Planetary Science Letters # Volume: 282 # Edition: # Issue: 1-4 # Pages: 167-177 # Report Number: # DOI: 10.1016/j.epsl.2009.03.013 # Online_Resource: # Full_Citation: Marx, S.

The trace element chemistry of deposited dust is used to identify the Australian source areas, and to calculate Australian dust deposition rates in New Zealand. This is used to infer patterns of aridity and climate variability in eastern Australia during the Holocene. Prior to 4800 cal. BP, dust deposition patterns imply that the Australian climate was relatively wet due to an active/persistent monsoon. Southern Australian source regions supplied the majority of dust transported to New Zealand at this time. After 4800 cal. BP the Australian climate became significantly more and and variable, attributed to the onset of ENSO-type conditions. The Lake Eyre Basin switched on as a dust source, while overall Australian dust deposition in New Zealand increased >4 times. Rates of Australian dust deposition were found to match patterns of increased ENSO variability, which is attributed to the combined effect of enhanced sediment supply to Australian dust source areas (during wet La Nina events) and preferable conditions for dust transport (during El Nino induced drought). Results also show that Australian dust deposition is a significant sedimentary process in New Zealand and is likely to influence both geochemical cycles and soil development suggesting that it may contribute up to 90% of material in the bog #--------------------------------------- # Funding_Agency # Funding_Agency_Name: # Grant: #--------------------------------------- # Site Information #
