Frontal regions of high chlorophyll fluorescence in the Strait of Georgia have been compared with calculated values of the stability expression, log,,(h U -' ) . Boundary areas of high chlorophyll were shown to exist at the northern and southern ends of the Strait as well as among the different island groups. These results have been used to discuss earlier differences noted in average annual primary productivity values of the Strait of Georgia, as observed over the last decade.

The Fraser River forms a well-defined layer of brackish water in the Strait of Georgia, with associated strong surface currents and salinity contrasts between it and the much deeper underlying waters. The numerical solution of a rotating, non-linear, reduced gravity, vertically integrated, upper layer model to describe the motion of this large river plume is described. Results from extensive field observations including tracking of surface drifters and CTD surveys are used to adjust and verify the model. Comparisons of observed and computed velocity and salinity fields show that the model simulates well the dominant flow patterns of the plume. A hindcast of two time periods in June and November 1986 is presented. Both hindcasts were characterized by periods of calm winds as well as the passage of reasonably intense storms, so that the response of the plume to wind forcing, as distinct from the wind-free situation, was quite well delineated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
