An Ultra-clean Multilayer Apparatus for Collecting Size Fractionated Marine Plankton and Suspended Particles

The distributions of many trace elements in the ocean are strongly associated with the growth, death, and re-mineralization of marine plankton and those ...

Vertical fluxes of total mass (F), particulate organic carbon (F), particulate inorganic carbon (F), Pb (F), and Po (F) were determined by sediment traps deployed at two depths, 2000 m and 3500 m, at SEATS (South East Asian Time-series Study, 116°00°E, 18°00°N) in the northern South China Sea during June 2008-June 2009. The F ranges from 12.2 to 55.1 mg m d and from 89.3 to 250.8 mg m d, at 2000 m and 3500 m, respectively, and shows seasonal and inter-annul variation. The temporal variation of F, F, and F were in phase with the F, which was coupled with the seasonal cycles of primary production in the euphotic layer. The F ranges from 5 to 48 dpm md and from 38 to 105 dpm md, at 2000 m and 3500 m, respectively. Contrasting with Pb, the F shows poor correlation with F. The F ranges from 3 to 146 dpm md and from 50 to 309 dpm md, at 2000 m and 3500 m, respectively. Episodic events of the settling of biological particles from the surface layer and the regeneration processes the deep layer control the Po removal in the water column of the South China Sea. Strong correlations of the flux and source ratio of Pb, (F/P), and the particulate carbon fluxes were found, which give relationships of F (μg cmy) = 26.8 + 371.0 (F/P) and F (μg cmy) = -1.4 + 533.1 (F/P).
