    Abstract

    Large variations in sinking rate of large-celled diatoms with a periodicity of ~10 s have their basis in cell density changes. Of the three mechanisms we model, the predicted energy cost is lower for periodic variations in the increase in cell volume than for variations in either the intracellular concentration of inorganic ions, or of organic solutes, that form solutions of different densities These predictions require experimental testing.
