ABSTRACT: The load of the
continental ice caps of the Ice Ages deformed the bedrock, and when the ice
melted in postglacial time, land rose. This process is known as glacial
isostasy. The deformations are compensated either regionally or globally.
Fennoscandian data indicate a regional compensation. Global sea level data
support a regional, not global, compensation. Subtracting GIA corrections from
satellite altimetry records brings—for the first time—different sea level
indications into harmony of a present mean global sea level rise of 0.0 to 1.0
mm/yr.
