Changes in Snow and Ice Extent: Fresh Water Ice Phenology Protocol

Freshwater Ice Formation

The purpose of the Freshwater Ice Phenology Protocol is to monitor the freeze-up and breakup processes on a selected pond/lake or large creek/river to determine the duration of the annual ice cover. Students will select an easily accessible pond/lake or large creek/river close to their school that is known to develop an ice cover in the winter and observe and document its freeze-up and break-up.
