Gunnar Spreen

Education
  • Ph.D. in Physical Oceanography, University of Hamburg, Department of Earth Sciences, Hamburg, Germany (2008)
  • Diplom degree in physics (comparable M.Sc.), University of Hamburg, Department of Physics, Hamburg, Germany (2004)
Research Interests
  • Satellite remote sensing with a specialty in sea ice using various satellite sensors (e.g. GLAS/ICESat, AMSR-E, SSM/I, SAR, QuikSCAT, MODIS) and techniques.
  • Gain a better understanding of climate processes, with an emphasis on sea ice - ocean interactions.
  • Data synthesis of sea ice remote sensing and model data.
