Ice regime study for the Ob-Yenisey estuaries using ERS SAR data

The ice parameters of the Ob-Yenisey estuaries are studied using synthetic aperture radar (SAR) data from ERS and RADARSAT satellites. Specific features of the Ob, Gyda Bays, Yenisey Gulf ice cover and Ob-Enisey recurring polynya has been accomplished and compared with wind and temperature observations. Based on the multi-temporal SAR, SLR radar and in situ observations the method for the support of practical navigation and off-shore operations at the western part of Siberia and Arctic is developed. A climatic study has also been made.
