Volume 2 l/Number 8/August 1990 compact for handling ashore, ensuring faster reaction to oil pollution treatment. The boom itself, specially designed and manufactured from polyurethane, is inflated upon deployment creating a fence around any oil that has been spilled, retaining it in one area so that treatment may be carried out. When not in use, each boom, approximately 250 m in length, is stored on a reel. This is in turn stored in a 10 ft enclosed container, together with a generator, diesel driven hydraulic power pack and a Poclain MS 18 braked hydrostatic wheel motor, used to control the deployment and retrieval of the boom. Poclain motors were used because of their infinitely variable speed and high load shaft bearings removing the need for a separate gear box and bearings which would have meant using a larger container. The resulting single lever operation also makes it easier for operators to deploy the boom at sea. Details of the system may be obtained from Poclain Hydraulics Ltd, Fieldhouse Lane, Marlow, Bucks.

Shipboard Sewage Treatment A new development in sewage treatment equipment for ships has been announced by Marine Ventures, UK distributors of the Omnipure electrocatalytic system of sewage disposal for ships. The system's design, which is US Coast Guard and IMO certified, does away with the tanks normally associated with factory-produced systems. Instead, process modules are supplied, making possible large volume sewage treatment with economical units of a small size. The 15MX module has a treatment capacity for 500 people, but measures only 2.2 m X 1.5 r e x 0 . 6 m. This unit can be retrofitted into existing ships. Other system sizes are available, down to the 4M model, suitable for a complement of 13. P&O's Fairstaris one of the vessels fitted with the system.
Sustainable Society Envisioning a Sustainable Society--Learning our Way Out. Lester W. Milbrath. State University of New York Press, Albany, New York, 1989. x v + 4 0 3 pp. ISBN 0-7914-0162-6.
This book has little to do with marine pollution per se, except as pollution of the seas features in the whole scheme of things in attaining a sustainable society. Although it is well written, the book is not easy reading. Besides, it's depressing. We now learn that all those things that we were taught by our parents and our teachers as being good are really bad. Aspirations of people in eastern Europe and in Third World countries
Standard Seawater Service The UK Company Ocean Scientific International Ltd now operate an International Association for the Physical Sciences of the Ocean (IAPSO) Standard Sea Water service. IAPSO Standard Seawater (SSW) is the only internationally recognized standard for the calibration of salinity measurement devices. Its widespread use over the past 90 years has been of great importance to the quality and comparability of salinity data worldwide. IAPSO continues to oversee the preparation of SSW and encourages the use of this standard by all laboratories involved in salinity measurement. Details may be obtained from: Ocean Scientific International, Brook Road, Wormley, Surrey, GU8 5UB, UK (Tel. 042-879-5245).
Smoother Paint to Replace Antifouling Increased environmental pressure and regulations are spurring chemical companies to produce alternatives to the current anti-fouling marine hull paints. Paint ingredients which prevent fouling by marine organisms have been found in food chains or the sea floor and this has caused concern. The new regulation, in some areas, has led to a new type of paint being developed by the US Coast Guard and it could replace the current antifouling paints in the future. It does not require such a critical temperature for application and so vessels could be painted at any time of year. It is known as the Plastic Flamecoat System and is applied with a torch gun mixing paint powder, propane and oxygen. It is applied directly to the metal. So far, the tests have shown the paint to provide a much smoother surface which will lower resistance to water flow. As the paint does not have antifouling ingredients, this could be a very important feature as marine organisms will grow more quickly on its surface.
of Africa and Asia for the 'good life' and the Nmerican dream', as often portrayed by western television, are all wrong, because that good life cannot be sustained. We should all be seeking the 'simple life' with minimum utilization of resources and little impact on the environment. The author starts out in Chapter 1 by imagining a movie that runs a full year representing all the time since the origin of the earth, about 4.6 billion years ago. The first signs of life, as one-celled microbes, occur in March and are the only form of life for another 2 billion years (August). Then more complex life forms (eukaryotes) develop' in about August and September. The larger and still more complex multi-cellular life forms do not occur until November. Dinosaurs appear on 407
