Summarizes what is known about two major variables involved in certain types of chemical pollution that seem to be changing the structure of the Earth's atmosphere. Discusses the greenhouse effect and the ozone layer. (TW)

This document reports on a survey that was conducted to determine the extent to which a random sample (N=2,112) of Maine public school teachers (K-12) included marine-related topics or activities in their teaching, as well as how informed they were about existing marine education curricula. A total of 588 questionnaires were returned. Findings…

States that tidal power projects are feasible in a relatively limited number of locations around the world. Claims that together they could theoretically produce the energy equivalent to more than one million barrels of oil per year. (TW)

While the open oceans remain relatively unpolluted, many coastal areas are suffering from oil, sewage, industrial wastes, and agricultural run-off. This document presents some of the key facts related to these kinds of water pollution. It focuses on the major sources of contamination in the world's seas, and provides an overview of how these…

Describes Ocean Thermal Energy Conservation (OTEC) as a method for exploiting the temperature difference between warm surface waters of the sea and its cold depths. Argues for full-scale demonstrations of the technique for producing energy for coastal regions. (TW)

Discussed are the costs of deriving energy from the earth's natural reserves of salt. Argues that, as fossil fuel supplies become more depleted in the future, the environmental advantages of salinity power may prove to warrant its exploitation. (TW)

This report of an international workshop contains recommended guidelines on marine science teaching and training at the first degree level, equated here with a Bachelor of Science, except in those countries in which the first degree corresponds to a Master of Science or its equivalent. Three instructional models are presented: the first model for…
