During December 2024, Hidde VanderZee enhanced the MITgcm-contrib/ecco_darwin repository by developing comprehensive documentation for a new 1-degree ECCO V4r4/V4r5 simulation configuration featuring the RADIv2 sediment metamodel. Focusing on text-based documentation, Hidde detailed the configuration’s structure and operational requirements, clarifying setup steps for advanced sediment-metamodel simulations. This work improved reproducibility and onboarding for users working with complex ocean modeling scenarios. By standardizing configuration notes and emphasizing discoverability, Hidde established a foundation for future downstream deployments. The contribution demonstrated depth in technical writing and domain knowledge, addressing a key need for clear, accessible documentation in scientific software projects.
