Hydrography and altimetry agree within 4 cm rms, except in the Southern part of the section (South of 5°S). In the Northern hemisphere, the correlation between the two data sets is about 0.80 and the two power spectra present the same energy level .... The hydrographic data show an unusual tongue of fresh water around 7°N that results in positive dynamic height anomalies of about 10 dyn cm. The GEOSAT data analysed during the same period also show these anomalies with a similar scale. (D'après résumé d'auteur) %$ 126TELAPP05
