Abstract:

Ocean Bottom Pressure time series from instruments deployed in the Southern Ocean are compared with GRACE products provided by different processing centres. Spatial correlation analysis of GRACE fields and the finite Elements FESOM model reveal considerable differences between different field. At the Southern Ocean OBP sites studied here, GRACE captures real oceanic mass variability, with small improvements by the recent release 04 data, On a global scale, a comparison of GRACE with the FESOM model revealed correlations of > 0.6 in most regions except part of the Atlantic.
