Book excerpt: Excerpt from Effects of Pollutants on Marine Organisms: Deliberations and Recommendations of the National Science Foundation, International Decade of Ocean Exploration, Effects of Pollutants on Marine Organisms Study, August 11-14, 1974 "Preserve the ocean environment by accelerating scientific observations of the natural stale of the ocean and its interactions with the coastal margin - to provide a basis for (a.) assessing and predicting man-induced and natural modifications of the character of the oceans; (b.) identifying damaging or irreversible effects of waste disposal at sea; and (c.) comprehending the interaction of various levels of marine life to permit steps to prevent depletion or extinction of valuable species as a result of man's activities." The above is the first of the six prescribed goals of the National Science Foundation's Office for the International Decade of Ocean Exploration. lit pursuit of this goal, IDOE, in 1971, carried out a one-year Baseline Data Acquisition Program and in the following year initiated the Pollutant Transfer Program. The Baseline Program indicated the present levels of contamination by trace metals and petroleum and chlorinated hydrocarbons in water, sediment and biota of the oceans. The Pollutant Transfer Program provides information on the pathways or mechanisms controlling the rate of pollutant transfer from the source to and within the ocean, the information so necessary for predicting the distribution of pollutants, for assessing whether the oceans are becoming measurably polluted, and ultimately for indicating rates at which pollutants may be released safely to the environment. The IDOE Effects of Pollutants on Marine Organisms Program is designed to learn whether the levels of pollutants shown to be present in the oceans in the Baseline and Transfer Programs are now having or may in the future have a deleterious effect on life in the sea. Such potential damage is the overriding reason for studies of ocean pollution. The goals of the research projects in the Effects of Pollutants on Marine Organisms Program were established as: (1.) to establish the level of pollutant just necessary to cause clear mortality for open ocean and coastal marine organisms: (2.) to determine the sublethal effects of pollutants on organisms; (3.) to learn the mechanism of pollutant effect on specific critical functions: (4.) to identify by careful chemical analyses the toxic or damaging chemical species. To attain these ends, a broad based program was designed around a matrix consisting of the pollutants of concern (trace metals, chlorinated hydrocarbons and petroleum and its products) and the various levels of marine organisms from bacteria to fish.
