El Nino has changing wind patterns. Wind pushes the ocean water around: It leads to the Eastern Pacific (America) being lower than the West (Asia) normally (surface wind goes west), normally about ~50cm above mean before Asia and about 20cm below mean before America. This changes during El Nino events, when the surface wind changes direction and the water is pushed the other way (~20cm below mean before Asia and 20cm above mean before America). Those values include thermal expansion and stuff. The Marshall islands are more to the Asia side of the Pacific. There is a ~20cm dip in 1998. [1] It fits.
