Abstract

Abstract

Water samples for suspended particles in water column were collected at 3 stations in the China Pioneer Area of Multi-metallic Nodules,the northeastern Pacific Ocean in July 2005.The samples of suspended particles were analyzed by ICP-MS,and contents of 47 elements from the particles were obtained. The barium and aluminum were chosen as the biogenic and terrigenous source tracers for the suspended particles,respectively.The barium contentranges from 0.02 to 0.19 μg/dm³ with the bio-barium content range from 0.01 to 0.13 μg/dm³,and the aluminum content ranges from 0.33 to 18.54 μg/dm³.The distribution of the bio-barium and aluminum of suspended particles and their ratio from the surface to the bottom in the water column corresponding to that of the TSM,which can be divided into three parts,was mainly caused by the distribution of biological process in the euphotic layer and the resuspension process of the seafloor sediment in the benthic layer.The decreasing tendency of the ratio of bio-barium to aluminum from marine benthic layer down to the seafloor reveals the evident change of the content and component of the suspended particles caused by the resuspended seafloor sediment in the benthic layer.Thus,their ratio can be regarded as an effective tracer of suspended particles exchange and transport in the benthic nepheloid layer.
