What is Coastal marine gravity modelling from satellite altimetry – case study in the Mediterranean about?
The coastal marine gravity eld is not well modelled due to poor data coverage. Recent satellite altimeters provide reliable altimetry observations near the coast, lling the gaps between the open ocean and land. We show the potential of recent satellite altimetry for the coastal marine gravity modelling using the least squares collocation technique. Gravity prediction error near the coast is better than 4 mGal. The modelled gravity anomalies are validated with sparse shipborne gravimetric measurements. We obtained 4.86 mGal precision when using the altimetry data with the best coastal coverage and retracked with narrow primary peak retracker. The predicted gravity eld is an enhancement to EGM2008 over the coastal regions. The potential improvement in alti-metric marine gravity will be bene cial for the next generation of EGM development.
