Short summary
Drift, landfast and glacier ice are present in fjords and it is important to map them separately. We developed a method to split fjord ice into different types based on ice location, persistence in time and size. We used this method for Hornsund fjord, home to the Polish Polar Station, for an 11.5-year period. We observed that most of the ice is drift ice. The maps produced by this study can be used to look at water circulation, coastal erosion and habitat conditions.
