  6. Relative gravimetry Gravity were determined for the Fundamental benchmark of the Third levelling of Finland at Metsähovi • Gravity were measured by FGI in the Department of Physical Sciences of the Helsinki University Finnish Geodetic Institute

  7. Satellite gravimetry J. Virtanen et al. Compared GRACE modelling with regional and local water storage models: Baltic Sea model (Finnish Institute of Marine Research) WSFS (Watershed Simulation and Forecasting system) of the Finnish Environment Institute) model Finnish Geodetic Institute

  9. Superconducting gravimetry, Metsähovi Finnish Geodetic Institute

  10. Superconducting gravimetry Metsähovi Finnish Geodetic Institute

  11. New 50.4 m long NSWT in Lohja mine (20 km west from Metsähovi) • 50.4 meter NSWT built in Oct-Dec 2007 • Tube and pots directly on bedrock with sand,concrete plates and triangle bricks 2 Finnish Geodetic Institute

  12. Finnish Geodetic Institute

  13. Geodetic-VLBI Geodetic-VLBI FGI/HUT team in Metsähovi participated on 8 geodetic VLBI campaigns in 2007 and 2 in the beginning of 2008. 2 Finnish Geodetic Institute

  14. Local crustal deformation measurements • - • Precise GPS network measurements and optical distance measurements continued 2007 in the vicinity of nuclear power plant Olkiluoto in south-western Finland • Repeated GPS measurements in possible nuclear waste location sites Olkiluoto, Kivetty and Romuvaara Finnish Geodetic Institute

  15. SLR Metsähovi • K. Arsov is developing a new Satellite Laser Ranging system in Metsähovi with kHz laser system. Telecope, recording facility and observation building are going to be renovated. Finnish Geodetic Institute

  16. DynaQlim DynaQlim –Upper mantle Dynamics and Quaternary Climate in Cratonic areas directed by M.Poutanen had a national meeting in Dec. 2007 and international meeting in Jan 2008 in Copenhagen. Finnish Geodetic Institute
