PREVENTION OF ICE FORMATION BY FORCED MIXING

In order to prevent the Rana Fjord from freezing due to increased winter inflow of fresh water from hydro power storage reservoirs, an air bubbler was installed at the mouth of the Rana River in 1968. Three seasons of successful operation have since proven the feasibility of this method of forced mixing under the given set of oceanographical and meteorological conditions. The mechanics of the mixing process are discussed in the light of observations made partly in experiments prior to construction, partly in situ after completion of the air bubbler.
