Physico-Chimie des eaux du golfe et de l’estuaire Saint-Laurent

Abstract

The dissolved oxygen content in the water of the Gulf of St. Lawrence varies approximately from 3 ml/l in the deep layers to 8 ml/l in the surface water layer. The minimum dissolved oxygen concentration is at a depth of 200 to 300 m, whereas the maximum is generally towards the bottom of the thermocline. As for as suspended matter is concerned, there is generally very little and the values seldom exceed 1 mg/l. Finally, the pH of the water and sediments varies from 7 to 8 and the concentrations of the trace elements in the region under study are very low and remain within the range of normal values reported for oceans. © 1980 Taylor & Francis Group, LLC.
