Chapter Seven Biochemical factors influencing deposition and erosion of fine grained sediment

摘要: Publisher Summary This chapter describes the biochemical factors influencing deposition and erosion of fine-grained sediment. Deposition fine cohesive particles are strongly influenced by factors, especially in intertidal environment. Organic matter, released algae bacteria, act as biological glue causes formation aggregates. Filter feeders, like cockles mussels, filter articles from water produce comparatively coherent faecal pellets. Diatoms bacteria slime that binds sediment particles. An important property suspension is they sensitive to flocculation. Flocculation results aggregates consist many small formed collision adhesion material suspension. The organic fraction will predominate during phytoplankton blooms at low suspended concentrations. Primary produced matter may greatly affect aggregation relatively It found not only accelerated flocculation but also through feeding bivalves, various hard-substratum zooplankton.
