The variations in sea level trends seen here primarily reflect differences in rates and sources of vertical land motion. (kaltesonne.de)
These are stations not experiencing significant vertical land motion. (kaltesonne.de)
Sea level change based on satellite altimetry is measured with respect to the Earth's centre of mass, and thus is not distorted by land motions, except for a small component due to large - scale deformation of ocean basins from GIA. (ipcc.ch)
