Marine geo-microbiology and biogeochemistry – cellular to planetary scale science
John Moreau (University of Melbourne)
Marine geo-microbiological and biogeochemical studies involve multi-disciplinary collaborations amongst microbiologists, geochemists, and chemical/biological oceanographers. Information about microbial activity, microbially-mediated nutrient and trace element transformations and the distributions and structures of microbial communities form the research foci of this rapidly developing field. Research problems can involve cellular scale processes with regional and planetary scale implications, such as the rate of seafloor methane cycling, the distribution and structure of phototrophic bacteria, and interactions between planktonic microbes and particulate organic matter in the marine water column. Current studies in these areas are advancing our understanding of the microbial components and mechanisms involved in defining the chemical and biological properties of the world’s oceans, and will yield insights into oceanographic modelling of large-scale biogeochemical nutrient and trace element cycles. This symposium invites researchers working in marine microbiology and geo-microbiology, biogeochemistry, isotope geochemistry, chemical and biological oceanography, trace element and/or organic biogeochemistry, and related topics to present their latest contributions to this advancing multi-disciplinary area within the Australian marine sciences. Contributions are particularly welcome from scientists working on geo-microbiological and/or biogeochemical research topics under the auspices of the Australia-New Zealand Integrated Ocean Drilling Program (International Ocean Discovery Program in 2011), the Australian Institute of Marine Sciences, and the Australian Center for Ecogenomics Research.
