Bridging environmental magnetism with biogeophysics to study biogeochemical processes of today

Session ID#: 82154

Session Description:
The development of biogeophysics revolutionized near surface geophysics by allowing the study of biological processes. An important outcome is a better understanding of how hydrocarbon-degrading microorganisms affect geophysical signatures. As a consequence, time can now be incorporated as a fourth dimension in geophysical investigations and provide geophysical methods environmental monitoring abilities, a capability especially important in pollution studies. In a different geophysical scope, environmental magnetism was developed to study events from the past, using powerful tools to identify fingerprints of magnetic minerals and discover their role in biogeochemical processes. New applications of environmental magnetism include issues of worldwide concern, such as contaminated soils and atmospheric pollution. Our ability to monitor and even promote environmental change through magnetic signals can evolve significantly by bridging these fields. We welcome submissions on all aspects of environmental magnetism and biogeophysics. Interdisciplinary studies and new analysis techniques are especially encouraged.
