* Assessment of the heat-flow in the Great Basin and the Snake River Plain using aeromagnetic maps. Methodology: study of the radial power spectrum of magnetic anomalies to estimate the depth to the bottom of magnetic sources assumed to correspond to the depth to the Curie temperature isotherm. * Study of the intensity fluctuations of the paleomagnetic field using marine magnetic anomaly profiles. Methodology: Computation of stacks of marine magnetic profiles for various oceanic basins. The comparison of these stacks shows the existence of worldwide coherent short wavelength anomalies (or tiny wiggles), associated, for most of them, to variations in intensity of the magnetic field. * Study of the statistical properties of the magnetic field produced by numerical geodynamo simulations. |
PhD Thesis: Study of the behavior of the Earth’s magnetic field during periods of stable polarity - Etude sur le comportement du champ magnétique terrestre durant les périodes de polarité stable. |
