We propose a new and improved recipe for inverting for crustal thickness variations from combined gravity and bathymetry data. The `new' ingredients with respect to previous studies are the posing of this problem as an inverse problem and the use of a downward continuation filter which can be tailored to find the crustal thickness solution which satisfies a minimum slope or maximal smoothness criteria, or a weighted combination of these desired solution features. We explore several suggestions for determining the `optimum' smoothing parameters for a given crustal thickness inversion. Then we compare this new method to that used previously in marine gravity studies. We find it to be an `improved' recipe for dealing with gravity data with observation errors of ~ 3-5 mGal, but not by much. This recipe will be most useful in extracting more geological information from marine gravity data where apparent observation errors are ~ 1 mGal, e.g. from future Global Positioning Satellite navigated studies.
