Short summary

Early data by pendulum instruments in Norway contributed to the first global gravity system. Spring gravimeters were used for a national gravity database, geoid computation, and for geophysical prospecting. Absolute gravimeters revealed gravity changes caused by land uplift since the last ice age. The first gravity data at sea were obtained in the Arctic Ocean. Current terrestrial and satellite data allow geodynamical studies relevant to climate change, caused by melting glaciers and ice sheets.
