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.
Prepare ‘the white paper” Responsible:
Dennis Conlon, Doug Lamb, Tom Carrieres, Chad Dick, Dean Flett
Status: International meeting outside of IICWG meeting deferred
until IICWG-4 meeting complete. White Paper prepared for discussion and review at IICWG-
4. IICWG-4 Science Workshop with theme on Modeling and
Data Assimilation to gather opinion and consensus on “Next Steps”
OPEN

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.
Responsible: TBD (suggestions - Florence Fetterer?; Michail Krasnoperov?; Vasily
Smolyanitsky?)
Status: Florence Fetterer and Vasily Smolyanitsky attended.
Fetterer presented poster entitled “Ice Chart Archive Formats: Progress in the IICWG”. Recommendations from the meeting are expected to lead to better cohesion among groups working on historical sea ice data.

Status continue: AARI's V.Smolyanitsky delivered a status report describing
both factual historical sea ice material submitted to the WMO project "Global Digital Sea Ice Data Bank" and derived climatic products, primarily based on AARI, CIS and NIC charts. In his report he pointed out on evidences for existence of multi-decadal oscillations and not 2-3 decadal linear trends and as well as possibilities of constructing blended datasets based on data sources from various ice services (Canada, Denmark, Japan, Russia, USA etc.). When constructed those datasets would potentially benefit accuracy of climatic investigations and numerical modelling.

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.
Responsible: Doug Lamb
Status: Doug Lamb sent out report entitled “Field Observation of
Arctic Sea Ice - Healy Cruise HY-01-03 - Sea Ice Remote Sensing and Modeling” to CIS, DNMI, and DMI in December, 2001.

Action (continuing): Continued coordination for ENVISAT and future Science field validation activities.
Responsible: All
Status: All approved AO PI’s were invited by ESA to begin
ordering ENVISAT data sets as of February 2003. All PI’s encouraged to coordinate activities and share
data sets.(e.g., Polarstern (5/4-19/4/03)+ Aranda (23/4-16/4/03) cruises – EU GreenICE and SITHOS projects – ENVISAT ASAR data acquisition coordination)

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

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.
Responsible: Science leads/contacts at respective ice services
Status: CIS has scaled back to ice/water separation and R&D for
development of tools to assist in ice analysis work flow NIC has discontinued work on automated ice typing at present DMI automatic ice/water classification with the aid of SAF and
SSM/I-85 GHz ice products – being evaluated. OPEN
