The north-south tilt in the Australian Height Datum is explained by the ocean’s mean dynamic topography

Using geodetic and oceanographic data, we show that the apparent north-south slope between the Australian Height Datum (AHD) and the geoid is caused almost completely by the ocean’s time-mean dynamic topography (MDT). This is because the AHD was constrained to zero height at local mean sea level at...
