This research is unique in that it undertakes to evaluate quantitatively 

 the characteristics of an estuarial seaway in terms of river discharge, 

 which is a readily observable monitoring factor. It provides a quantita- 

 tive measure of pollution and shows how it may be evaluated from a 

 knowledge of the properties of the pollulant, and the oceanography of 

 the system. Finally, it offers a precedent for the prediction of the 

 probable degree of pollution from industrial development, which in turn 

 permitted adjustments to be made before the fishery was damaged. 



The field-work was done between 1939 and 1942, but development 

 of the data was interrupted by the war and was only completed in 1948. 

 The research is reviewed in detail in three papers, which are to be published 

 as a bulletin of the Fisheries Research Board of Canada (Ottawa) : — 



(1) Oceanography of Alberni Inlet. J. P. TuUy. 



(2) Prediction of Pulp Mill Pollution in Alberni Inlet. J. P. TuUy. 



(3) A- Hydraulic Model of Alberni Harbour. J. P. Tully, H. J.
