| Abstract | Molluscs collected from the Strait of Canso in 1973 as part of the study undertaken by the Environmental Marine Geo logy Section of the Atlantic Geoscience Centre are useful indicators of environmental
change in the area. Differences in the surface faunas compared with the uniform fauna representation below a 10 to 25 cm barren zone observed in cores taken north and south of the causeway show the marked effect the causeway, completed· in 1954, has
had on the marine environment. In the Strait south of Point Tupper, a thin (5 to 10 cm. ) barren zo ne overlies mollusc-bearing sediments and delimits the extent of the area affected by industries located along the eastern shore of the Strait. Exotic
species mixed with endemic species in several of the cores may indicate the presence of interglacial or reworked interglacial deposits in the area. |
