Abdelali Fadil, Lydie Sichoix, Jean-Pierre Barriot and Pascal Ortéga of the Tahiti geodesic observatory and Pascal Willis of the IGN and IPGP used sea level observations on Tahiti as part of a study into the indications of slow subsidence of the island of Tahiti.

Vertical speeds of the island of Tahiti were estimated based on several independent geodesic measurements, notably 17 years of differential altimetric measurements obtained between temporal series of altimetry and tide gauging.

Their results are recorded in the article entitled "Evidence for a slow subsidence of the Tahiti Island from GPS, DORIS, and combined satellite altimetry and tide gauge sea level records" that appeared in Volume 343, Number 5 of the "Comptes Rendus Geoscience" (Geoscience Reports), on pages 331-341 (May 2011), Doi: 10.1016/j.crte.2011.02.002.
