| The effect of a sewage plume on the biology, optical characteristics, and particle size distributions of coastal waters was evaluated around the Sand Island, Hawaii, outfall diffuser. In situ physical and biooptical data and Niskin bottle samples were collected during a 1-week cruise from September 25 to October 1, 1994. One or two layers affected by sewage could be distinguished in the water column: recently discharged (''new'') sewage plume waters and ''old'' plume waters. In conditions characterized by high Froude number the distribution of chlorophyll fluorescence in new plume waters was the same as for ambient waters, while for low Froude number, chlorophyll fluorescence increased within the plume, demonstrating the importance of physical forcing on... |

| ADCP data from two cruises, Moogli 2 (June 1998) and Moogli 3 (January 1999), show the variability of the circulation features in the Gulf of Lion, NW Mediterranean Sea. The objective of the present study is to determine whether the hydrodynamic features are due to local forcings or seasonal ones. During both cruises, the Mediterranean Northern Current (NC) is clearly detected along the continental slope and intrudes on the eastern side of the shelf. East of the gulf, its flux is similar to2 Sv both in June and January in opposition to previous literature results. Otherwise, the NC characteristics exhibit usual seasonal differences. During the summer, the NC is wider (35 km), shallower (similar to200 m), and weaker (maximum currents of 40-50 cm s(-1)) than... |
