Short summary

As ice sheets grow and shrink, they move rocks around. In Scandinavia the movement took place mostly from inland to offshore areas, resulting in ongoing uplift in Scandinavia and subsidence in offshore areas. This study calculated the changes in height and gravity and found that they are significant. Thus, effects of past sediment loading have to be taken into account when interpreting measurements of height and gravity change in areas close to former ice sheets with large sediment transport.
