Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "A means of recording the presence and quantity of frazil ice, over an extended period, has been devised using a calorimetric method. A prototype system was tested in the laboratory and gave reasonable data. In one of the field tests, the sensing body was placed ahead of the trash rack of a hydroelectric generator. Comments are made on the first field data. Improvements in the prototype are required. The use of a profiling mechanism is proposed"--Abstract.
