Seasonal Ice Zone Observing Network (SIZONET)

  Local sea-ice experts, who are also experienced hunters and community leaders, provide daily written sea-ice observations assisting this project to more thoroughly understand the evolution of the local seasonal ice zone from a user perspective. These observations help in identifying key dates in the annual evolution of the local ice cover, such as the first appearance of slush ice or the beginning of break-up. Observations help to assess ice stability as specific notes are kept related to deformation events and the distribution of key features such as grounded ridges or multiyear ice floes. In addition to the collection of written observations, interviews are performed with other experienced members of the communities, especially during our efforts to summarize the state of the local sea-ice cover for a given year. Local experts also provide general guidance for our field research campaigns and often take part in the on-ice collection of some of our geophysical-based datasets, such as the EM thickness surveys. Both the written ice observations and transcripts from interviews are being entered into an ice observation database where they are archived in a searchable format.
