Sédimentation marine : définition de Sédimentation …

Mécanismes. les mécanismes qui régissent la sédimentation marine sont liés à la production des particules minérales ou biologiques (la neige marine) qui vont en grande partie se déposer sur les fonds océaniques. La nature et le mode de transport de ces sédiments influeront sur leur texture, densité et nature physicochimique, de même que les organismes qui y vivent (animaux ...Sedimentation - an overview | ScienceDirect TopicsSedimentation coefficient distribution profiling has also been used to good effect for detecting interactions in mixed polysaccharide systems used for health applications.

The suspension liquid is kept still and the balance of the tensiometer measures the mass change of the sedimentation probe within a time period. The higher the mass change is, the faster the sedimentation process occurs.
