Two-dimensional line source air bubbler systems used to induce convective melting of the undersurface of an ice cover over a water body are analyzed and a procedure is developed for predicting the effectiveness of the systems. Various field conditions are considered and limitations to the effectiveness of the systems are pointed out. Example applications of the concepts and the procedures are illustrated in the Appendix.
