Biogeomagnetism, Biogenic Magnetic Minerals, and the Environment
Session ID#: 80833
Session Description:
Organisms mineralize magnetic minerals directly or indirectly, and use them for known and unknown purposes in various natural processes within the present and past environments on Earth. We solicit contributions on all research aspects that will further the understanding of biogeomagnetism. Examples include, but are not limited to: the mineralization of magnetotactic bacteria and other Fe(III)-reducing and Fe(II)-oxidizing microorganisms in natural habitats and laboratory cultures; magnetic properties and potential applications of biogenic magnetic minerals; magnetofossil records at critical transitions in the geological past (e.g., polarity transitions, hyper-thermal climate events, mass extinctions), and their contributions to sedimentary magnetism; origin and evolution of magnetotaxis in microbes; magnetoreception and magnetic navigation in higher organisms; long-term correlation of deep-time geological and paleomagnetic records. Experimental investigations and theoretical modeling of the influence of changing geomagnetic fields on organisms and the biosphere as a whole (and through associated cosmic radiation influx variability) are also solicited.
