-OceanBioME.jl is a flexible and friendly ocean biogeochemical modelling environment. It is highly modular and is designed to make it easy to implement and use a varitey of biogeochemical and physical models. OceanBioME is built to be coupled with physics models from [Oceananigans.jl](https://github.com/CliMA/Oceananigans.jl) allowing simulations across a wide range of spatial scales ranging from a global hydrostatic free surface model to nonhydrostatic large-eddy simulations. OceanBioME was designed specifically for ocean CDR appplications. Notably, it includes active particles which allow individual-based models to be seamlessly coupled with the flow physics, ecosystem models, and carbonate chemistry.
