Continuous GNSS (GPS) Observation
SYOG was the 7th station to be registered with IGS, and is recognized as an indispensable station in Antarctic research.
Crustal movement in Antarctica as seen by IGS Data
Movements of Antarctica by analysiis of IGS data (1996-2009)
It seems that each observation point moves centering on off thecoast SYOG in clockwise direction. This is because that Antarctic plate containing Antarctica moves in clockwise direction, not because Antarctica itself deforms.
Also, signnificant uplift can be seen at observation point (OHIG, PALM) in Antarctic Peninsula.
|Analysis Organization：||Geography and Crustal Dynamics Research Center, Geospatial Information Authority of Japan|
|Data Period：||1996 - 2009|
|Analysis Strategy：||IGS 30s RINEX data was processed by PPP(Precise Point Positioning) with GIPSY-OASIS 6.0|
Site velocities were estimated by fitting the coordinate time series to linear line.
