OCIM Workshop Report
This workshop, held June 23, 2019 at Woods Hole Oceanographic Institution, was attended by 22 researchers from 18 different institutions. This tutorial-based workshop focused on teaching participants to use the Ocean Circulation Inverse Model (OCIM) for biogeochemical modeling. Participants were introduced to the basics of transport matrix calculations using MATLAB, and learned to build simple to moderate-complexity biogeochemical models using OCIM. Topics covered in the workshop included simulations of ventilation age and water-mass tracers; simulations of preformed tracers and analysis of preformed and regenerated nutrient distributions; gas exchange and simple gas tracer simulations; introduction to multi-tracer models using simple models of organic matter production and remineralization; iterative methods vs. direct methods for solving large systems of equations; and using Newton's method to find equilibrium solutions to non-linear models. Participants received sample codes and an OCIM instruction manual for future reference.
