Processing code and Jupyter notebooks for a comprehensive global ocean radiocarbon (Δ¹⁴C) dataset (1700–2024). The workflow compiles ship-based dissolved inorganic carbon measurements and biogenic carbonate archives (corals, bivalves, gastropods, and sclerosponges), assigns synthesis quality flags (DELC14QC), runs deep-ocean crossover diagnostics, and generates figures for the accompanying ESSD manuscript (Mamnun et al., in preparation). This deposit is software only. The compiled CSV products, source index, and data README are archived at https://doi.org/10.5281/zenodo.18674659.
