Winter Hydrology and Ice Regime of the Ob –yenisey Estuaries: Results of Satellite Sar Comprehensive Studies
نویسندگان
چکیده
Winter hydrology and ice regime of the Ob and Yenisey estuaries, including the ObYenisey recurring Polynya are studied with using satellite ERS /RADARSAT/Envisat SAR and multi-spectral data obtained by satellite “Resours”. Results of satellite microwave sounding of sea, brackishand fresh-water ice in this area are attracted. Sub-satellite field experiments of the coastal zones were provided onboard nuclear icebreaker “Sovetsky Soyuz”, “Jamal” and “Arktika”. Comprehensive studies of ice cover parameters of shallow water in the Ob Gulf were organized in frame of ARCDEV experimental voyage onboard icebreaker “Kapitan Dranytsyn” (April-May 1998). Yenisey Gulf and Ob-Yenisey estuaries were investigated onboard i/b “Vaygach” and “Taymir” in frame of several pilot studies that were provided in the Siberian Arctic since October 1993 till now.

CoRe-H2O - A dual frequency SAR mission for hydrology and climate research
Taking into account the needs for improved, spatially detailed observations of snow and ice in climate research, hydrology, and glaciology, the satellite mission COld REgions Hydrology High-resolution Observatory, CoRe-H2O, was proposed to ESA. As payload a coand cross-polarized Ku-band (17.2 GHz) and X-band (9.6 GHz) SAR was selected, because of its sensitivity to dry snow, thin sea ice, and t...

متن کاملToward Monitoring Surface and Subsurface Lakes on the Greenland Ice Sheet Using Sentinel-1 SAR and Landsat-8 OLI Imagery
Supraglacial lakes are an important component of the Greenland Ice Sheet’s mass balance and hydrology, with their drainage affecting ice dynamics. This study uses imagery from the recently launched Sentinel-1A Synthetic Aperture Radar (SAR) satellite to investigate supraglacial lakes in West Greenland. A semi-automated algorithm is developed to detect surface lakes from Sentinel-1 images during...
متن کاملAn Assessment of Ice Effects on Indices for Hydrological Alteration in Flow Regimes
Preserving hydrological variability is important when developing environmental flow regimes, and a number of tools have been developed to support this process. A commonly applied method is the index of hydrological alteration (IHA), which describes a set of indices that can be used to assess changes in flow regimes. In cold climate regions, river ice can have large effects on flow regimes throu...
