A. Bowie (ACE-CRC) Research Voyage ss2011_v02 Australian-New Zealand GEOTRACES GP13 Australasian GEOTRACES: A collaborative international study of the marine biogeochemical cycles of trace elements and their isotopes along a zonal section (GP13) of the Pacific Ocean east of Australia. Scientific Objectives: This project will undertake an integrated oceanographic transect and dust monitoring program for iron, other trace elements, and their isotopes (TEIs) along the western end of the GP13 zonal section (~30oS) east of Australia. Our innovative measurement and analysis strategy will identify processes and quantify fluxes that control the distributions of key TEIs in the southwestern Pacific Ocean, and establish the sensitivity of these distributions to changing environmental conditions. We will use a series of novel techniques to fingerprint the sources, sinks and internal cycling of TEIs, focussing on the atmospheric delivery of irondust to the remote ocean. This project will provide maximum scientific reward for evaluating future global change, and has strong international collaborative activity under the auspices of the international GEOTRACES ( program. Outcomes of this project will be an improved ability to predict climate-driven changes in the supply and biogeochemistry of trace elements in ocean waters around Australia. Our research will quantify the importance of atmospheric dust for marine ecosystem health, help inform Government policy on ocean iron fertilisation as a carbon sequestration strategy, and provide a broad basis for evaluating future climatic changes in coupled atmospheric ocean processes.
