A new global transfer function (admittance) between oceanic geoid and seafloor depth has been derived for the wavelength band 1000--4000 km, after removal of lithospheric cooling effects using the most recently published crustal ages of the oceans. In this wavelength band, the admittanc is positive, reaches a maximum of ~5m/km around 2750 km wavelength, then decreases to ~2.5 m/km, on the average, at shorter wavelengths (between 2500 km and 1000 km). These values are systematically higher by 30--40% than those we derived in a previous study using crustal ages of poorer quality. In view of these new results, we cannot exclude that part of the signal at the 2750 km wavelength is of convective origin, unlike the conclusions of the previous study. On the other hand, at shorter wavelengths, the observed admittance can still be interpreted in terms of crustal thickening and sediment loading. ¿ American Geophysical Union 1987
