Any time the water flowing under an ice cover has a temperature above freezing, there is an exchange of heat between the water and the ice. Earlier work by Ashton and others provided adequate explanations and mathematical formulations based on the available field data at that time. However, more detailed water temperature measurements on the La Grande River in the James Bay region have pointed out anomalies with respect to the previous analyses. This information, along with work published recently by Matousek, has been used to develop what appears to be a more reliable relation. The object of the paper is to describe the chronological evolution of our understanding of the ice-water interface heat exchange up to the present.
