Phosphorus Dynamics & Lake Eutrophication

One of the projects I carried out as part of my PhD decision process is nearly finished now. Or let’s say it is finished, but I am still writing it up. I have published my Matlab code on my Git repository, so feel free to have a look.

I have reimplemented a model on lake eutrophication developed by Carpenter (2005). It is a very neat mathematical model that can predict eutrophication and algal blooms. However, this model does not take into account the role of the biota explicitly. I attempted to fill this gap, but had to discover that essential data to take out this model extension in a justifiable way is missing. Therefore my report will be a position paper that points out gaps in knowledge and gives suggestions on how to fill these gaps with the sampling of further lake data.
