GiantKelpDynamics.jl is a Julia package providing a dynamical model for the motion (and in the future the growth and biogeochemical interactions) of giant kelp (Macrocystis pyrifera).
The kinematic model is based on the work of Utter and Denny, 1996 and Rosman et al., 2013, and used in Strong-Wright and Taylor, In Review.

We have implemented it in the particle in the framework of OceanBioME.jl and coupled with the fluid dynamics of Oceananigans.jl.
Please note that the release v0.0.1 accompanies the publication A model of tidal flow and tracer release in a giant kelp forest (Strong-Wright and Taylor, 2023) and contains the version of the code used for the experiments in that work. We do not recommend using that version and suggest that the current version is used as it has been substantially rewritten to improve the maintainability of the code (while leaving the mathematical model of the motion unchanged) and therefore a significant amount of breaking changes have been introduced since this version.
The kinematic model discretises each kelp individual into segments to which several forces: drag, buoyancy, tension, and inertial, are applied. This is shown in this diagram:
Further details can be found in Strong-Wright and Taylor, In Review.
The model is designed to be used to simulate kelp forests and reproduce their motion (Strong-Wright and Taylor, In Review). This figure shows an example of the flow around a forest:
