Abstract

Research was conducted to monitor arctic river ice conditions in Siberia. The lack of traditional hydrological measurements in those remote inaccessible regions makes the use of satellite data a key technique in obtaining information on their hydrological cycle. The Global Flood Detection System (GFDS) based on microwave satellite data of AMSR-E system was used to observe river ice conditions in the polar region. The orbital gauging observations are serving the basis of artic river monitoring. The ice break-up in spring is a significant change in the river condition well detectable by the GFDS system. Variations in the time-series of several years can be mean to quantify effects of global climate change. Results show more significant change in the spring melting than in the freezing period. The ice-break up is showing more variation in Siberian rivers than in those of North-America. For this reason only the break-up period in the Siberian rivers was investigated. Limitation of the system is the length of the time-series still the trend shows that the period of ice-break up in the rivers are moving towards early spring.
