Abstract

Abstract

Data of water depth,temperature,salinity and suspended particles samples at 12 stations in the Pacific Ocean were collected in 2005.According to the vertical distribution of suspended particles concentration,the distributing characteristics of marine nepheloid layers are primarily analyzed and compared in different marine conditions,and origins of these particulate matter are discussed.The concentration of suspended particles in an ocean water volume is very low,generally less than 0.3 mg/dm³.While in some layers the concent ration of suspended particles is relatively high,then the nepheloid layers are formed.In the oceans,they generally occur as surface and near-bot to mnepheloid layers everywhere.The formation of surface nepheloid layers is mostly influenced by euphotic biology,while the resuspension of bottom sediments plays an important role on the formation of near-bottom nepheloid layers.At the top of seamounts,there are no nepheloid layers because of for mation influence of water current and rock base,while the nepheloid layers occur more frequently at the bottom and the China Pioneer Area.In the western China Pioneer Area near volcanicorifices,the concent ration of suspended particles is higher than that in the eastern.
