Abstract

Primary productivity in oceans is related to the amount of carbon and organic matter, which depends from a series of factors that spans from temperature, nutrients availability, ocean circulation, oxic-anoxic conditions, amount of CO2, fresh water and atmospheric changes. For those reasons defining the primary productivity conditions allows to understand climate changes, pollution distribution, ocean acidification, response to tectonic events, run-off variations, faster carbon cycle along time and how the ocean system respond to those environmental variations. The complexity of the carbon cycle along geological periods enhances the solution to understand future climate changes. Magnetotactic bacteria are prokaryotes that are capable to intracellularly biomineralize magnetite of an ideal single domain size (magnetosomes) for moving along the optimal oxic-anoxic conditions. However, bacterial magnetite has only been reported in a few pre-Quaternary records because progressive burial into anoxic diagenetic environments causes its dissolution. Nevertheless, the biogeochemical factors that control magnetotactic bacterial populations in such settings are not well known. We would like to document the environment and the preservation of bacterial magnetite, which dominates the palaeomagnetic signal throughout recent sediments from Brazilian Coast. Our aim is to search for magnetotactic bacteria and understand the microbial ecosystems and environmental change related to their presence in sediments. We would like study magnetotactic bacterial populations in marine settings depending crucially nutrients availability in the water column and in sediments, on particulate iron and organic carbon delivery to the seafloor, to understand the environmental condition that allow the presence of magnetotactic bacteria and magnetosomes in sediments.
