This session explores the interactions between Earth’s magnetic field and life, from the origin, evolution and mechanisms of magnetoreception to broader impacts of geomagnetic field on ecosystems and planetary habitability. It seeks to integrate perspectives from earth sciences, biology, environmental sciences, and biomedical applications.
The geomagnetic field is a fundamental component of Earth’s system, shielding the biosphere from solar and cosmic radiation, modulating atmospheric processes, and influencing evolutionary pathways. Its temporal and spatial variability throughout Earth's history may have profoundly shaped the Earth’s habitability and the biosphere. Understanding these linkages is crucial not only for reconstructing past Earth systems but also for assessing planetary habitability beyond Earth.
We welcome contributions on: (i) the behavior and dynamics of Earth’s ancient and present magnetic field and its environmental consequences, including changes in radiation, atmospheric chemistry, and climate; (ii) the influence of Earth’s magnetic field on prebiotic chemistry and the origin of life; (iii) biological responses to magnetic fields in microorganisms, animals and ecosystems, including potential roles in Phanerozoic mass extinctions and evolutionary radiations; (iv) methodological and theoretical advances in magnetic measurements, with emphasis on innovations for detecting weak magnetic signals and biominerals; and (v) applications of biogenic magnetic nanoparticles in Earth science and beyond.
This session will bring together researchers from earth sciences, biology, environmental sciences, and planetary science to exchange ideas and foster interdisciplinary collaboration. It will provide a platform to strengthen biogeomagnetism research and to explore its implications for planetary habitability.
