We investigated coccolithophore fluxes from four sediment traps located in the northeastern Arabian Sea at the continental slope of Pakistan. Two moorings, WPT and EPT (Western/isastern PAKOMIN Trap), consisting of one and two sediment traps were deployed at water depths of about 500 m and 1500 m. They collected settling particles from October 1993 to February 1994 and from May 1995 to February 1996 at intervals of 22 and 24 days, respectively. A longer sampling was prevented probably due to high sedimentation events which occluded the trap cones. Both areas were characterised by a strong seasonality in coccolith fluxes. High fluxes were recorded with up to 2000 _ 106 coccoliths m?2 d?1 in the early SW (summer) monsoon and up to 5400 _ 106 coccoliths m?2 d?1 in the early NE (winter) monsoon. Generally, coccosphere fluxes exhibited a similar trend but were some orders of magnitude lower than coccolith fluxes. Twenty-seven taxa were identified in this study, all well to moderately well preserved and with a small range of diversity. The species composition was dominated by Gephyrocapsa oceanica, Florisphaera profunda, and Emiliania huxleyi making up about 70% of the assemblages. During the SW (summer) monsoon high productivity in the surface waters of the eastern Arabian Sea may be linked to the upwelling system off Oman. Apparently, nutrient-rich surface water derived from the southwestern upwelling areas off Oman with high standing stocks were carried into this area by northeast flowing currents. In contrast, during the NE (winter) monsoon the locally observed high coccolithophore production is hypothesised to respond to local injections of nutrient-rich deep water into the surface water due to sea-surface cooling leading to convection. Consequently, fluxes during the winter monsoon were in the same range as during the summer monsoon. 24 pp., 9 figs, gr. 8. …

Taschenbuch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - The Northwest African and the conjugate Northeast American con tinental margins provide excellent examples of mature passive continental margins which record in their thick sediment cover the birth and evolution of the Atlantic Ocean Basins during the past 200 million years. Due to a dense net of single- and multichannel seismic reflection lines, numerous Deep Sea Drill ing Project (DSDP) sites and petroleum exploration wells, and the well-known onshore geology, the Northwest African margin is one of the bes't-documen ted margins of the world. A particu lar advantage of this margin is that its coastal basins are well exposed and accessible for detailed stratigraphic studies and onshore-offshore correlations, whereas the Mesozoic-Ceno zoic marginal basins off eastern North America underlie only the present continental shelf and slope. During the past decade, the Northwest African margin was stu died in great detail, particularly by the Woods Hole Oceano graphic Institution, Lamont-Doherty Geological Observatory, Imperial College London, Shell Internationale Petroleum Maat schappij (Den Haag), Kiel University, and the Bundesanstalt fiir Geowissenschaften und Rohstoffe (BGR) at Hannover. A num ber of important synthesis papers summarized these results; e. g. , Summerhayes et al. , 1971; Dillon and Sougy, 1974; Seibold and Hinz, 1974; Uchupi et al. , 1976; Lehner and de Ruiter, 1977 (all quoted in the references of Seibold, this Vol. ).…
