The results of 44-year integrated observations of the Kara Sea shore dynamics in the area of the VSEGINGEO Marre-Sale Station have been presented. The multi-year on-land registration of the sea shoreline retreat to the distance of 4.5 km in combination with detailed drilling of the shore zone and with the use of remote research methods enabled the authors to reveal the basic regularities in the manifestation and dynamics of destructive and accumulative processes within this area. The use of GIS-technologies have allowed one to obtain for the first time the objective qualitative data about the shoreline retreat and bottom areas of the shore cliffs (average and interval values) both for the total period of observation and particular periods. The real state of the shoreline in the station area and its dynamics are clearly registered by large-scaled aerial photos and video¬images taken in different years. Data of the remote sounding of the Earth (RSE) in the station area demonstrate the active manifestation of the geodynamic processes in the mouth of the Marre-Yakha river.
