Deep chlorophyll maxima (DCMs) are widespread in large parts of the world's oceans. These deep layers of high chlorophyll concentration reflect a compromise of phytoplankton growth exposed to twoâ€¦ (More)

Phytoplankton require light for photosynthesis. Yet, most phytoplankton species are heavier than water and therefore sink. How can these sinking species persist? Somehow, the answer should lie in theâ€¦ (More)

The paper introduces a new numerical method for continuation of equilibria of models describing physiologically structured populations. To describe such populations, we use integral equations coupledâ€¦ (More)

We motivate and analyse a reaction-advection-diffusion model for the dynamics of a phytoplankton species. The reproductive rate of the phytoplankton is determined by the local light intensity. Theâ€¦ (More)

We analyze the predictions of a reaction advection di usion model to pinpoint the nec essary conditions for bloom development of sinking phytoplankton species in strati ed waters This reveals thatâ€¦ (More)

We are interested in the efficient solution of linear second order Partial Differential Equation (PDE) problems on rectangular domains. The PDE discretisation scheme used is of Finite Element typeâ€¦ (More)

The ecological condition of the Continental Shelf is of great concern for many countries. The understanding of the integrated effects that result in the present and future situation requires answersâ€¦ (More)

This paper is concerned with the time integration of semi-discretized, multi-dimensional PDEs of advection-diffusion-reaction type. To cope with the stiffness of these ODEs, an implicit method hasâ€¦ (More)
