Jul 1, 2025July 2025: Progress on the ECCO-Darwin Arctic ecosystem modeling effort in MITgcm-contrib/ecco_darwin. Delivered v6 Arctic ecosystem modeling setup with robust configuration for biological and physical parameters, including plankton type dimensions, optical properties, wavebands, and diagnostic outputs at daily and monthly scales. Aligned diagnostic outputs to AO ecosystem naming to improve downstream analysis and reproducibility. Created an AO simulation setup documentation (build/run steps, module loads, input data linking, tracer modifications, and diagnostic directory creation) for 1992–2024 in the v06 1-degree Darwin3 model. Minor but impactful diagnostic fixes updated data.diagnotics to AO ecosystem, enhancing consistency across experiments and reports. These deliverables improve reproducibility, accelerate onboarding, and enable more reliable AO studies across teams.
