Primary ice data of interest is simply ice thickness and how this changes over time on rivers and lakes including when if forms and melts or breaks up. Data is also collected about bedfast ice (when water bodies freeze solid to shallow lake- or river-beds), snow cover on ice, and ice conditions such as overflow. Using a combination of satellite remote sensing, in situ real-time sensors and cameras, and field measurements, along with historic records and sometimes models, we strive to represent ice conditions at relevant scales in time and space.
