Current Projects

I have produced a new model for the geomagnetic field consisting of a central axial dipole and a series of vertical off centered dipoles placed within the core to give the correct slope to the Lowes-Mauersberger function. The off centered dipoles are statistically concentrated towards the geographic poles so as to give the right variation of VGP scatter as a function of observation latitude. The model statistically explains the scatter of VGPs without any low latitude cutoff. This has been submitted for publication in Gcubed
I have recently published a paper in Geologisches Rundschau (2000) on a new model for the mechanical erosion rate.
I have produced a power spectrum of sea level changes spanning about fifteen orders of magnitude in frequency, with periods from 5 seconds to 600 million years. This has been published in Gcubed (2002). I am presenting further ramifications about this topic at the fall 2002 AGU meeing
With colleagues at Scripps Institution of Oceanography I am working on realistic model for the large magnetic anomalies recently detected over part of the southern hemisphere of Mars. We presented a paper on these results at the 1999 fall AGU meeting in San Francisco
