Submersible operations in Georgian Bay and Lake Erie — 1970 / P.G. Sly. : En36-515/44E-PDF

"Most of the studies undertaken by the Limnogeology Section are directed towards obtaining a clearer understanding of geologically recent and present environmental controls, particularly those related to eutrophication and pollution. Research activities have mostly been conducted from surface vessels, using standard sampling, coring and sensing equipment. However, some detailed surveys and equipment trials have been supported by scuba diving techniques (Sly l969a), and over the past three years, the demand for diver supported operations has grown progressively. The need to understand sediment distributions and to quantify variations, which can be used to reflect short—term environmental changes as they relate to specific problem areas (Sly 1969b), has also become more and more evident"--Introd.
