Abstract

The data which was obtained from 1993 to 2014 by 28 permanent GNSS-stations around the Gulf of Finland were used to study geodynamics of this region. It was the first case of using the data from the St. Petersburg Urban Planning and Architecture Committee’s stations. Geodynamics of this region is interesting because it is a very old geological transition zone between the Baltic Shield and the East European Platform. The PPP strategy of GIPSY 6.3 was used for calculation of the station position time series which were corrected with consideration of the atmospheric loading effects. The station velocities were used to assess the strain field of this region. The strain field was estimated by the algorithm that considers at predetermined points the strain tensor as the symmetric part of the velocity gradient. Strain components were found on the basis of the Least square method and the smoothing covariance function. The velocity vectors of stations referred to the Baltic shield demonstrate a small local rotation of the Baltic Shield in the counterclockwise direction with respect to the East-European platform. The strain field has a weak (less than 3 nanostrain/year) compression in the direction from the northwest to the southeast

AB  - The data which was obtained from 1993 to 2014 by 28 permanent GNSS-
stations around the Gulf of Finland were used to study geodynamics of
this region. It was the first case of using the data from the St.
Petersburg Urban Planning and Architecture Committee’s stations.
Geodynamics of this region is interesting because it is a very old
geological transition zone between the Baltic Shield and the East
European Platform. The PPP strategy of GIPSY 6.3 was used for
calculation of the station position time series which were corrected
with consideration of the atmospheric loading effects. The station
velocities were used to assess the strain field of this region. The
strain field was estimated by the algorithm that considers at
predetermined points the strain tensor as the symmetric part of the
velocity gradient. Strain components were found on the basis of the
Least square method and the smoothing covariance function. The
velocity vectors of stations referred to the Baltic shield
demonstrate a small local rotation of the Baltic Shield in the
counterclockwise direction with respect to the East-European
platform. The strain field has a weak (less than 3 nanostrain/year)
compression in the direction from the northwest to the southeast
