  1. International Ice Charting Working Group Sponsored by: U.S. National Ice Center Office of Naval Research Canadian Ice Service Hosted by: Arctic and Antarctic Research Institute

  2. IICWG-IV • April 7-11, 2003 • IICWG agenda to be set after outcome is determined from WMO/JCOMM meeting

  3. Technical Tours Museum displays on: The Arctic Environment History of the Northern Sea Route Culture of Northern Regions Antarctica

  4. US/Canada Joint Ice Working Group Sixteenth Meeting held April 29- May 1 in Wood’s Hole, Mass.

  5. JIWG 2002 • Standing Committees • Operations, Icebergs, Technology & Systems, Science and Remote Sensing • Theme: North American Ice Service • Developed NAIS Plan of Action • NAIS to be signed following signing of umbrella NESDIC/MSC IMOU, anticipated Fall 2002

  6. IICWG -III Action Items: Plenary 1. Co-chairs of IICWG to inform WMO/JCOMM Sea Ice Expert Team (SIET) that Ms. Cheryl Bertoia will represent IICWG to the SIET. 2. Mr. Klaus Struebing to provide Mr. Eric Madsen with the URL the Baltic Sea Ice Meeting. 3. Ms. Florence Fetterer to place the CEOS Ice Hazards Report on the IICWG website. 4. Each ice center head to provide a training website URL to Mr. Paul Seymour/Mr. Keld Hansen. 5. A working group is established in order to establish guidelines for the development of these training web pages. This group shall include Mr. Seymour (NIC), Mr. Hansen (DMI), Dr. Tangen (DNMI) and Ms. Bourque (CIS). 6. The Data Access Sub-group to work toward release of an informal "request for information" for IICWG Consortium commercial SAR data access within the next six months. DASG to investigate possible relationship of IICWG informal RFI to NOAA formal RFI. 7. DASG to consider expanding work beyond access to space based SAR, to include other near-real-time sensors such as MODIS and QuikScat. 8. DASG to look to future sensors in the 8-10 year time frame and make recommendations to the IICWG. 9. DASG to consider whether to establish itself as a standing committee or to remain a sub-group of Data, Information and Customer Service.

  7. Action Item Report of theApplied Science & ResearchStanding Committee IICWG International Ice Charting Working Group

  8. Modelling & Data Assimilation (1) • Action: • Convene ice/ocean modeling and data assimilation workshop targeted for late 2002 or early 2003 - location TBD. Summary of workshop outcome to be reported on at IICWG-4 in St. Petersburg. • Responsible: • Dennis Conlon, Doug Lamb, Tom Carrieres, Chad Dick, Dean Flett • Status: • CIS offered to host but experiencing financial difficulties, TBD (Aug 2002)

  9. Modelling & Data Assimilation (2) • Action: • Coordinate and develop project and/or proposal focussing on data assimilation for submission to funding opportunities. • Status: • NASA Data Assimilation Workshop held July 02 at USNA, Annapolis. CIS and NIC attended and presented operational community interests.

  10. Ice Archives & Climatology • Action: • Attend and present summary & inventory of available digital and non-digital ice service ice archives at ACSYS/CliC-organized Sea Ice Extents Workshop, April'02. • COMPLETE

  11. Validation and Analysis (1) • Action: • Facilitate timely release of preliminary results and findings from the Healy Cruise. Make data available to other researchers as necessary to support research activities. • COMPLETE: JPL final report provided to IICWG members • Action: • Continued coordination for Envisat and future Science field validation activities. • Continuing

  12. Validation and Analysis (2) • Action: • Pursue development of project proposal on use of Visible/Infrared data (e.g. for ice typing, classification, cloud-masking, etc.) for submission to funding opportunities. Investigate opportunity for Visiting Scientist visit to DNMI. • Responsible: • Lars-Anders Breivik, Roger De Abreu, Doug Lamb • Status: • NIC investigating sending Dr Joerg Haarpaintner to DNMI

  13. Validation and Analysis (3) • Action: • Provide information to the group and coordinate communication on QuikScat (SeaWinds) data and algorithm access and evaluation. • COMPLETE

  14. Improving Accuracy of Ice Charts& Transition of Science to Operations • Action: • Revisit Ice Classification problem. Science groups at each ice centre to consider own requirements and desired methodology for machine-assisted segmentation and classification and exchange ideas and concepts. Ice agencies to develop regional training and validation data sets to allow for training and/or testing of tools and systems. • CONTINUING: • NIC will make available a validation data set of 34 manually classified RADARSAT images.

  16. Data, Information and Customer Support • Action Item CD 2.3 - Each ice centre to gather an inventory of ice chart data attributes and post this inventory on the IICWG web by March 15 2001. (Florence Fetterer, NSIDC) • Draft ice chart attributes table is on the IICWG web. • Status: Open

  17. Data, Information and Customer Support • Action Item CD 2.4 - IICWG participants to gather information on climatological products produced by each service and provide this information to Florence Fetterer by December 2000.

  18. Data, Information and Customer Support • Action Item CD 3.1 - Colour Code Standard. • Colour code to be finalised by the end of December 2001. • Each ice centre to produce internal charts using the agreed colour code for the period January to October 2002 and inform the working group about any difficulties encountered. • Revised colour code to be presented to the JCOMM Expert Team on Sea Ice in October 2002 for adoption.
