| Summary: | An unusual humped formation of floating ice, about 10 m. high, 100 m. wide and 1,200 m. long, was observed on the Ottawa River, Canada. Some characteristics of this formation are described. The cause of the humps was found to be frazil ice deposited in a trench about 90 m. wide, 90 m. deep and 1,200 m. long. The frazil ice was formed in rapids up-stream from the humps. Une formation bombée inhabituelle de glace flottante d' environ 10 mètres de haut, 100 mètres de large et 1 200 mè tres de long a été observée sur la revière Ottawa, Canada. On décrit quelques caractéristiques de cette formation. On attribue les bombements à du sorbet (mélange laiteux de glace et d'eau) déposé dans une fosse, d'environ 90 mètres de large, 90 mètres de profondeur et 1 200 mètres de long. Le sorbet a été formé dans des rapides en amont des bombements. Peer reviewed: Yes NRC publication: Yes |
