Issued also in French under title: Sources de pétrole dans l'environnement marin. "September 1996." "It is interesting, and somewhat surprising, to realize that the oil which so concerns us when it is released to the ocean, actually began its existence in the oceans themselves. Petroleum is a fossil fuel that occurs naturally, and is produced from the decay of plant material. But this plant material actually originated in the ancient seas of the planet as tiny aquatic organisms. Over countless millions of years, immeasurable numbers of these organisms were incorporated into marine sedimentary rocks. As time progressed, natural physical and chemical forces acted on this material to eventually form petroleum. It is a fact that the greatest volume of the worlds oil reserves are now found in these sedimentary formations"--Introd. gccst Water pollution gccst Petroleum Canada. Environment Canada.
