Abstract

[Truncated] Phytoplankton population dynamics are controlled by the relative rather than absolute timescales of mixing, growth, and loss processes such as sedimentation,grazing etc. In the first part of this thesis, the vertical distribution and biomass of phytoplankton populations are quantified by two timescale ratios: the Peclet number Pe, the ratio of mixing and sedimentation timescales, and the growth number G, the ratio of sedimentation and net growth timescales. Three mixing regimes are defined for phytoplankton and other particles. For Pe≥100, the population is translated linearly down the water column over time, and will leave the surface mixing layer completely after sedimentation time T_s.
