IAMAS, IAPSO and IACS invite the international atmospheric, oceanographic and cryospheric research community to MOCA-09, their Joint Assembly, to be held in July 2009 in Montréal, Québec, Canada.
THE DEADLINE FOR THE SUBMISSION OF ABSTRACTS IS JANUARY 23, 2009
J13 Biogeochemistry and Climate
Conveners: Denise Smythe-Wright (IAPSO), Leif Anderson (IAPSO), John P. Burrows (IAMAS), Melissa Lafrenière (IACS)
Description: Global climate change is being driven by anthropogenic modification of the atmospheric composition primarily by the release of long lived greenhouse gases by the combustion of fossil fuels but also by the generation of short lived greenhouse constituents, resulting from air pollution and changes in land usage. However the response of the terrestrial and oceanic biospheres to climate change is highly non linear and inadequately understood. Measurements of atmospheric composition provide an early warning of the likely changes and Climate chemistry models are being developed to provide accurate prediction of change. Ocean observations have revealed a warmer and less alkaline ocean during the last decades and models tell us that this trend will likely continue and that the ocean will become stormier and less nutrient rich by the end of this century. How this will impact upon ocean biogeochemistry and its interaction with the atmosphere is unclear. Current research is addressing these important themes as we enter the next phase of the anthropocene. This symposium will focus on all aspects biogeochemistry and including climate and ecosystem model development. We particularly welcome contributions on carbon dioxide, methane and nitrous oxide measurements and their regional and global trends, carbon dioxide uptake, ocean acidification, carbon export, eutrophication/nutrient depletion, impacts of dust deposition due to storms and trace constituent measurements and the fluxes of short lived precursors.
