Deep-water intrusions

An essay moving between philosopher of science Isabelle Stengers, Haida mythteller Skaay, and the North Pacific Ocean. In Flemish (transl. Samuel Vriezen) in nY issue 32, Jan 2017, a special issue on Isabelle Stengers; or read my English original here. “What strikes me, as a modern student of the non-human members of Skaay’s marine landscape, … Read more

Coltrane (Copepod Life-history Traits and Adaptation to Novel Environments)

The Coltrane (Copepod Life history Traits and Adaptation to New Environments) model is a mathematical framework for layering multiple levels of mesozooplankton biology on top of oceanographic models. It resolves 1) individual life history (strategy traits controlling growth, development, and size, diagnosed from a broad review of lab studies); 2) population dynamics (the time-dependent energy … Read more

Adding fine-scale trophic complexity to a plankton model

Natural plankton communities are far more diverse than even a very complicated numerical model can account for. The ASTroCAT model (Allometric/Stochastic Trophic Complexity Analysis Tool) is an experiment in systematically resolving the complexity in phytoplankton–microzooplankton trophic interactions, and exploring the effects of this complexity on ecosystem structure, function, and predictability. The model runs interactively in … Read more
