3. 2. Detection and classification of sea ice from spaceborne multi-frequency synthetic aperture radar imagery and radar altimetry

   Författare :Wiebke Aldenhoff; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Beaufort Sea; sea ice classification; sea ice; sea ice concentration; Fram Strait; SAR imaging; radar altimetry;

   Sammanfattning : The sea ice cover in the Arctic is undergoing drastic changes. Since the start of satellite observations by microwave remote sensing in the late 1970's, the maximum summer sea ice extent has been decreasing and thereby causing a generally thinner and younger sea ice cover.

4. 3. Satellite Radar Altimetry for Determination of Geoid Undulations and Gravity Anomalies

   Författare :Jonas P. Noréus; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resolution; water vapour; geodesy; geoid undulations; gravity anomalies; precision; kriging; satellite remote sensing; radar altimetry;

   Sammanfattning : The sea level changes both temporally (due to dynamic effects) and spatially (due to sea bottom topography and inhomogeneities in the Earth's crust). Satellite radar altimetry is a remote sensing technique which can be used for e.g. determination of the instantaneous and mean sea level, and gravity anomalies at sea. LÄS MER
