Abstract
Several new satellite altimetry missions have started delivering data that will seriously improve global high resolution gravity fields. The impact of these new geodetic mission data is significant with the quality of the altimetric gravity field nearing that of marine gravity observations in many regions. We demonstrate the quality of the new satellite altimetry data by comparison to high quality marine gravity data over the Capel and Faust basins, offshore Eastern Australia. An improvement of 10% is seen in the region in comparison with vintage altimetric gravity fields. Over the sampled wavelengths, the DTU13 gravity data appears to have the best resemblance to the reference marine gravity data, exhibiting the overall least difference amplitude over most wavelengths.
