Influence of GIA on Ocean Mass Variations

We use three GIA models (R F3L20, Pau-5-R a and Pel-5-VM4-R) to correct the re-sult of the ocean mass variations derived from GRACE (Gravity Recovery and Climate Exper-iment) during 2004 - 2010 . The corrected results are compared with the ocean mass variations estimated from combination of the Altimetry Satellite data and the ARGO (Array for Real-time Geostrophic Oceanography) data. We find that the result of 'Altimeter-Argo' agrees better with the ocean mass variations corrected by Pel-5-VM4-R GIA model than the correc-tion results with the other two GIA models. Base the above results, we recommend that Pel-5-VM4-R model is more appropriate to correct the ocean mass variations, and the contribu-tion of the ocean mass variations to the mean sea level is 1.5-2.0mm/a.
