2. Gravity field variations:
Our plans (as applied to DFG)
“The Fennoscandian Land Uplift:
a Test and Application Area for GRACE”
Absolute gravity determination with FG5-220 in Fennoscandia
in 2006: 15 stations
in 2007: 15 stations
in 2008: ~7 or 8 stations
(incl. reference and comparison measurements) }
Gravity field variations:
gravity and geoid change caused by recent uplift in Fennoscandia
(surface point and area information, models)
2008/2009: summing up and unifying of data sets (gravimetry and GPS height rates)
joint IfE /(FGI, KMS/DNSC, LM, SK) gravimetry campaigns
data exchange with partner institutes:
consideration of earlier campaigns (e.g. Wilmes et al. 2004) and recent campaigns with other absolute meters (UMB, BKG, FGI, NOAA)
BIFROST and latest GPS results

4.
reasonable record from the dipper: seasonal behaviour (low (!) water table in August),
assuming a porosity of 5% of Aksla: 3 m water table change may cause up to 5 μGal.

5. Absolute Gravity Determinations:
r = 0.90, dg/dGW = 0.18 μGal/cm
