Methods The St Lawrence Estuary and the Saguenay Fjord (Fig. 1) were sampled in summer At each station sampling was preceded by a CTD cast (conductivity- temperature-depth), from which sampling depths were chosen, using a profiling system model from Guildline Instruments Ltd.

Water samples were obtained with 5 by: The Saguenay Fjord Provincial Park Saguenay St-Lawrence Marine Park A fjord is a glacier valley filled with water with tides can rise up to 6 meters.

The Saguenay Fjord is unique due to its marine life and its km lenght, that expands from Chicoutimi to Tadoussac.

The St. Lawrence Estuary and Saguenay Fjord ecosystem The St. Lawrence River Estuary (SLE), Quebec, Canada is one of North America’s major estuary (Fig.1).

The concentrations reflect the fate of the surface waters of the Fjord in the St. Lawrence Estuary. the flow of the Saguenay is directed on the South by: To study the response of the estuary to winter forcing, observations from three moorings for the winter of /03 will be used.

The moorings were located in the northwest gulf (NWG), the lower St. Lawrence Estuary (SLE), and at the head of the Laurentian Channel (HLC) (shown in Fig.

Quebec'c Health Minister hesitates over fluoridation of drinking water as public health authorities say yes, and the public says : Caroline Plante. Fluoride is found naturally throughout the world -- in soil, fresh and salt water, and in foods.

Fluoride may be used by individuals in the form of toothpastes, rinses or applied professionally in the form of gels, foams or varnishes. In optimal concentrations, fluoride protects the.

The level of oxygen in the St. Lawrence estuary has fallen significantly in recent decades. The causes and long-term effects of this phenomenon are poorly understood and worry researchers.

The affected underwater region is located near Tadoussac and off Rimouski. The oxygen that marine life depends upon has fallen by roughly half since the s, according to Alfonso Mucci, a professor in.
