Ice Watch is a system which coordinates the collection and archival of sea ice observations recorded on ships in the Northern Hemisphere. It provides open-source software for recording and sharing shipborne Arctic sea ice observation data (ASSIST), and supports users who wish to collect data using these systems.
Since 2012, the Ice Watch website, ASSIST software and other services have been hosted and developed by the Geographic Information Network of Alaska and the University of Alaska Fairbanks. However, after many years Ice Watch has now moved to a new home at the Norwegian Meteorological Institute. You can now find Ice Watch at:
As part of this transition, all existing users will need to re-register if you wish to continue using the new website. You only need to register if you wish to submit data or receive email updates. Observation data is freely available to download from the website.
At the Norwegian Meteorological Institute, we have a number of plans to develop the Ice Watch System including continued development of the ASSIST system and making the data easier to access. We also are working with the Polar Citizen Science Collective to develop a new citizen science app allowing a simple interface for users to submit observations. For updates on these and other future developments keep checking the news here and follow our social media accounts:

If you are planning a cruise in the Arctic and are interested in collecting sea ice observations, we encourage you to contact us for details of how to get involved. Likewise, if you use or publish work using Ice Watch data we would like to hear from you so we can keep track of how the data is used.
