1.      Absolute gravity campaigns

 

The absolute gravity meter FG5-220 of IfE (Hannover) has visited Denmark in the period June 2-12, 2003.  Four stations have been measured.

 

·        Buddinge. Close to the permanent GPS station and Pille 1, the fundamental gravity station of the danish presicion gravity network. The site is not anymore in the hands of KMS, which is why it was important to move it. A marker on the floor marks the station. The station was levelled by KMS.

 

·        Vestvolden. The new absolute gravity station in Copenhagen located in a building housing a seismological archive. After the gravity measurenment, the station has received a marker on the floor. The station was levelled by KMS.

 

·        Helsingør. Hall of a school (10 klasses skole). The station lies on the 56ºN land uplift gravity line.

 

·        Tebstrup (near Skanderborg, Jutland). Old peoples home. The station lies on the 56ºN land uplift gravity line.

 

 

2.      Land uplift gravity lines

  

Participation in two international relative gravity campaigns along land uplift gravity lines:

·        63ºN line with the Finnish Geodetic Institute and Lantmäteriet

·        56ºN line with Lantmäteriet

 

 

3.      Others
