Bordeaux Colloquium
The M a r i n e Pollution Bulletin is published monthly and sets out to cover all aspects of the fight for the life of lakes, estuaries, seas and oceans. It includes news, comment, reviews and research reports not only on the threats of noxious substances to marine life but also on the management and productivity of the marine environment in general. It publishes accounts of new and proposed research programmes as well as the results of those in progress. C o n t r i b u t i o n s may be in the form of short notes not exceeding 650 words or articles of 1 5 0 0 - 2 0 0 0 words and should be submitted to the editor in double-spaced typescript. They should be given a short one-line title and the text should be broken by short sub-headings. All measurements must be given in metric (S.I.) units. Reprints of articles can be supplied after publication and an order form for them is sent to contributors. Bulk orders of copies of the entire issue in which an article appears can be supplied at a reduced rate to the author, provided they are ordered in advance of publication. Edited by: Professor R. B. Clark, Department of Zoology, The University, Newcastle upon Tyne, England NE1 7RU. Marine Pollution Bulletin is published by Macmillan Journals Ltd., 4 Little Essex Street, London WC2R 3LF. Annual subscription £6.00 (£7.50 USA and Canada). (Payment may be made in any currency at the current exchange rate. Orders must be accompanied by remittance. Prices applicable only to subscriptions started before 31st December, 1974.) Cheques should be made payable to Macmillan Journals Ltd., Subscription Department, Brunel Road, Basingstoke, Hams. RG21 2XS, England.
Investigations at ten sites around the British coast were reported; these were mainly concerned with the variability of coliform counts and discussed the factors which had been found to influence their rate of disappearance. Feasibility studies for sea disposal schemes were described for the Gulf of Trieste and Maiori, Italy. It was clear from this Congress that the Mediterranean countries can obtain technological information from both their own research work and the findings of the many programmes being carried out elsewhere. Attention should be g~ven to the design of local programmes to avoid duplication and to draw on published data. A. R. AGO
Bordeaux Colloquium The Second International Colloquium on the Exploitation of the Oceans, to be held in Bordeaux on 1-4 October, 1974, is expected to provide a forum for the interchange of ideas and information, from industrialists, people involved in marine trades, and academics. The first colloquium in March, 1973 provided an opportunity for an international comparison of existing research programmes (with their appropriate results) and of strategies involved in industrial development with respect to the oceans. It is intended that the second colloquium should attempt to find some solution to the conflicts already arising among the different forms of exploitation of marine resources, or among different categories of utilization: oil, mining, shipping, fishing, and aquaculture. The provision of a rendezvous every three years in Bordeaux (in conjunction with the International OCEANEXPO--Offshore Exhibition) may attract those people, such as scientists, engineers, lawyers, managers, and economists, whose discussions may result in some progress towards the proper utilization of a resource rather than the exploitation of an environment.
European Geology and Petroleum major coastal waste disposal projects. Considerable information has been obtained on the uptake of organic and metallic toxicants by primary populations and their concentration in predators. Tuna fish caught in the Mediterranean contain nearly 2.5 times as much mercury as the same species from the Atlantic. Observations in the Black Sea and the Caspian Sea show that the reproduction of algae has been reduced by oil; some species were adversely affected by oil concentrations as low as 0.01 mg/l. Experience from California in the design of sewage disposal schemes shows that greater protection of the environment is achieved, for a given level of investment, by discharging wastes, after only minimum treatment, into deep ocean water beyond the shallow coastal zone rather than employing advanced treatment methods and discharging the effluent near the shore. New EPA policy, however, is now forcing coastal authorities to meet effluent quality standards which cannot be achieved by efficient secondary treatment. In 1973, Italy defined legal requirements for permissible limits for pollutants in recreational waters. It was reported from Sweden that discharges of mercury from the manufacture of chlorine have been reduced by 90~o to 20 g/t chlorine produced. 48
The first joint meeting between geologists and environmental affairs advisers will take the form of a conference at the Bloomsbury Centre Hotel, London on 25--29 November, 1974, and will be sponsored jointly by the Geological Society of London, the Institute of Geological Sciences, the Petroleum Exploration Society of Great Britain and the Institute of Petroleum. The geology and geophysics of the continental shelf of north-west Europe will be considered, followed by a discussion on the related theme of pollution and other environmental problems associated with the search for petroleum and its production and transportation. The Conference will include sessions on the geology of the outer shelf from Biscay to north Norway, North Sea oil and gas fields, sources and mechanisms of spillage, physical and biological effects. The release of information, particularly that concerning appropriate subsurface geology and geophysics, will be sought from companies exploring the area, and it is hoped that representatives from associated organizations in some of the north-west European countries will take part. Further details may be obtained from C. H. Maynard, Gen. Sec. (Admin.), Institute of Petroleum, 61 New Cavendish St, London WIM 8AR.
