Effects of the Cessation of Sewage Sludge Dumping at the 12-Mile Site: Proceedings of the 12-Mile Dumpsite Symposium, Ocean Place Hilton Hotel, Long Branch, New Jersey, 18-19 June 1991

This study owes its inception to the wisdom and experience of the staff of the Northeast Fisheries Science Center who, after several decades of surveys in the New York Bight, recognized a unique opportunity to capitalize on the decision to stop ocean dumping of sewage sludge and designed an innovative field study to evaluate effects on living marine resources and their habitats. For decades ocean dumping was viewed as a cheap and effective means for disposal of wastes generated by urbanized coastal areas. Even after the 12-mile site was closed, sewage sludge continued to be dumped at Deepwater Dumpsite 106. The 6-mile site off the NewJersey coast is still used as a dumpsite for dredged material from New York Harbor areas. Discussions continue on the propriety of using the deep ocean spaces for disposal of a variety of material including low level radioactive wastes. Consequently, managers are still faced with critical decisions in this area. It is to be hoped that the results from the 12-mile study will provide the necessary information on which these managers can evaluate future risks associated with ocean waste disposal.

Aquatic ecology, economy and society: the place of aquatic ecology in the sustainability agenda

This article explores aspects of sustainability and the importance of sustainable development, including the place of the crucially important resource of fresh water and of freshwater ecosystems. It examines the treatment of natural resources by the economic system that underpins global business, outlines some progress towards more sustainable approaches to business, and recommends steps to re-establish science as the driver of wise policies that contribute to sustainable development.

Variation des bio-volumes des zooplancton du plateau continental entre le Cap des Palmes et le Cap des Trois Pointes

Three years of weekly sampling from a coastal station and 29 monthly cruises over the whole continental shelf were studied for zooplankton quantitative variation. Settled volumes were preferred to displacement volumes. At the coastal station, near Abidjan, a negative correlation was found between the log2 of zooplankton volume and the preceding fortnight temperature. On the whole shelf, the differences between the 6 considered areas were tested by the variance analysis. There were significative differences in shallow waters only (20 m). During the main cold season, the upwelling of Tabou causes a very important enrichment 30 to 60 nautical miles to the east. Eastwards the plankton drifts and decreases in abundance. The zooplankton maximum is not always inshore, but often in the middle of the shelf and sometimes over the slope. During the little cold season the enrichments caused by coastal upwelling are less abundant and restricted to smaller areas. During the warm season, the waters are uniformly poor. During the cold season, over the 60m depths, the zooplankton maximum lies between 10 and 20 m and seems to sink in deeper waters. In warm season the vertical repartition is rather homogeneous in the first 40 meters. The diel vertical migrations show a very consistent rhythm, varying with the season.

Construction and Operation of a Two-place Diver's Sled

Fisheries gear researchers have employed scuba diver-operated sleds to evaluate towed fishing systems since the early 1950's. One of the earliest sled designs was a converted Stokes litter in which two divers sat tandem with the forward diver operating the diving controls (Sand, 1956). The litter was relatively easy to maneuver and provided a comfortable platform for observing operational fishing gear. However, the use of underwater photographic equipment to document gear performance was difficult due to the limited mobility of the observer-cameraman.
