3 Background & Motivation Sea ice motion tracking developed 15+ years ago as a state-of-the art computer science research topic Sea ice motion tracking developed 15+ years ago as a state-of-the art computer science research topic Within sea ice, motion-tracking development has made little progress mainly due to lack of funding. Within sea ice, motion-tracking development has made little progress mainly due to lack of funding. There is an increase in There is an increase in navigational traffic in the Arctic navigational traffic in the Arctic more integrated science projects more integrated science projects There is a need to increase development of ice motion tracking within the sea ice community in an accessible form so the knowledge base can increase.

15 Overview of Program Successes 144 images provided through ASF NIC UD interface 144 images provided through ASF NIC UD interface ~100 image pairs analyzed at UD ~100 image pairs analyzed at UD Turn around time from downlink at ASF to completed product at UD < 2 hours Turn around time from downlink at ASF to completed product at UD < 2 hours Biggest impediment was ice camp delivery Biggest impediment was ice camp delivery Iridium satellite phones still too slow Iridium satellite phones still too slow Daily “Gold Streak” courier service of DVD with all camp needs ($30 per delivery) Daily “Gold Streak” courier service of DVD with all camp needs ($30 per delivery) Anticipate greater potential to shorten delivery time to a ship with greater bandwidth transmission. Anticipate greater potential to shorten delivery time to a ship with greater bandwidth transmission. 15

16 The Next Step Submitting a proposal to NSF logistics to turn this into a near-commercial product (5 year) Submitting a proposal to NSF logistics to turn this into a near-commercial product (5 year) Wish to develop this into a product using GRASS as a GIS display tool Wish to develop this into a product using GRASS as a GIS display tool UD research team is willing to serve as the initial hub to set up infrastructure to disseminate and maintain development updates, user’s manual feedback, product developer interface system, etc. UD research team is willing to serve as the initial hub to set up infrastructure to disseminate and maintain development updates, user’s manual feedback, product developer interface system, etc. Proposal overview sheet provided through Pablo Proposal overview sheet provided through Pablo 16

17 Summary Successful coordination of SAR motion analysis from satellite to pickup site in less than 2 hours Successful coordination of SAR motion analysis from satellite to pickup site in less than 2 hours Seeking funding (Nov 10) to develop near-commercial version with free distribution for non-commercial applications (education, research, logistics, government agencies) Seeking funding (Nov 10) to develop near-commercial version with free distribution for non-commercial applications (education, research, logistics, government agencies) 17

18 REQUEST A letter of support from IICWG. Potential as a resource in support of navigation and safety in ice-covered waters Potential as a resource in support of navigation and safety in ice-covered waters Statement saying that you would work with this research team to disseminate this product to the international navigational community for non-commercial applications Statement saying that you would work with this research team to disseminate this product to the international navigational community for non-commercial applications 18
