%X We investigate two ocean models for model validation and the altimetry data from TOPEX/Poseidon (T/P) and conclude that the mass transfer within the oceans, specifically within the Pacific Ocean, contribute to at least part of the variation of the Earth oblateness ( J 2 ) since 1997/1998. The abnormal J 2 variation since 1997/1998 may be from the variations of the steric effects, which are the result of thermal and saline variation, and might not be easily discerned from the sea surface height variations observed with the T/P data.
