DESCRIPTION:Cryosphere from space: the role of multi-polarisation synthetic
  aperture radar observations\n\nDott.ssa Mozhgan Zahriban Hesari\n\nThe cr
 yosphere includes far more than the sea ice and icebergs that move through
  polar waters. It also encompasses the extensive ice tongues\, coastal gla
 ciers\, and frozen coastal areas that extend from land into the ocean. The
 se places are always changing. Their shifts affect the global climate\, ho
 ld clues about past environmental conditions\, and shape ecosystems on lan
 d and in the sea. Understanding how these frozen regions behave is crucial
  for tracking climate change\, refining estimates of sea-level rise\, and 
 ensuring safe work and travel in polar and coastal areas.\n\nDue to the ha
 rsh environment characterising polar regions\, including inaccessibility\,
  adverse weather conditions as frequent rain\, snow and significant cloud 
 coverage\, and limited solar illumination\, spaceborne Synthetic Aperture 
 Radar (SAR) represents a valuable and irreplaceable observation tool that 
 allows getting information on a large scale at fine spatial resolution wit
 h sub-weekly temporal coverage.\n\nDuring the seminar\, several showcases 
 will be presented to emphasise the potential of time-series of dual-polari
 metric Sentinel-1 SAR measurements\, which are provided free of charge fro
 m the European Space Agency through the Copernicus Data Space Ecosystem\, 
 to address meaningful tasks. They include a robust and effective unsupervi
 sed detection and morphological tracking of icebergs and ice fronts belong
 ing to ice tongues and marine-terminated continental glaciers.\n\nThe goal
  is to show how it is possible to get useful information from SAR imagery 
 collected over the cryosphere and the role played by partial polarimetric 
 information to support a continuous and updated observation of polar regio
