  1. Shell SAR R&D Studyfor ice operations Kim Partington, Polar Imaging Paul Verlaan, Shell

  2. Background to Study • Shell is nearing completion of its first season of custom ice monitoring in Alaska • We are entering an era of more choice for satellite SAR sensors • Good time to review SAR data strategy

  3. RADARSAT-1 Need to replace RADARSAT-1 2007 ops 2008 ops 2009 ops 2006 2009 2005 2007 2008

  4. RADARSAT-2 COSMO-SKYMED-1 COSMO-SKYMED-2 COSMO-SKYMED-3 COSMO-SKYMED-4 RISAT RADARSAT-1 ALOS ENVISAT Available SAR sensors TERRASAR-X X band C band L band 2006 2007 2008 2009 2005

  5. Objectives • To make recommendations to Shell with regard to their 2008 SAR planning for ice operations • To consider both: • Imaging capabilities of new SAR sensors • Fit of different sensors to Shell operational requirements

  6. Limited backup and redundancy Sub-optimal revisit Imaging ambiguities Operational issues Ordering lead time Price Consider more than one SAR Use more than one polarisation (/frequency?) Capabilities are improving, not sure about price! Traditional SAR issues that can now be addressed.. }

  7. Various options…

  8. RADARSAT-2 RISAT Dual Polarisation ScanSAR X band Credit NASA JPL C band L band 2006 2009 2005 2007 2008

  9. X band ScanSAR X band COSMO-SKYMED Sub-daily revisit C band L band 2006 2009 2005 2007 2008

  10. Plus others.. • ALOS L band ScanSAR • Global mode? • Finer resolution polarimetric mode for occasional detailed operations? • Complementary combinations of the afore-mentioned Credit Vexcel UK and ESA

  11. Study Plan

  12. Camden Bay Shell operations Potential validation from operations Custom ice charting Circumpolar Flaw Lead study area Scientific campaign coordinated by University of Manitoba Ship and airborne observations Potential links to CIS validation plans for RADARSAT-2 Shell R&D study: areas

  13. RISAT RADARSAT-1 ENVISAT Shell R&D Study: Data Collection TERRASAR-X R&D study data X band Operational data COSMO-SKYMED C band RADARSAT-2 ALOS L band 2006 2009 2005 2007 2008

  15. Study Outcome • Provide a report in March 2008 in time for 2008 planning covering: • Imaging benefits of the different sensors • Operational strengths and weaknesses of the different sensors • Acquisition plan strategies • Include: • X band vs C band vs L band • Dual pol vs single pol • Focus on freeze-up conditions including young ice

  16. Conclusions • We are now entering a new era for SAR remote sensing • Much improved potential for ice monitoring • But needs work to realise potential • Shell is investigating what can be done for ice monitoring in time for the 2008 season • Any changes to default plan will depend on cost and operational performance as well as technical capabilities of different sensors • Interested to talk to others with interests in comparison of the different SAR sensors

  17. Thank-you!
