Data and code for "Time of emergence of climate signals in the abyssal Clarion–Clipperton Zone and implications for deep-sea mining baselines"

Data and code supporting the paper "Time of emergence of climate signals in the abyssal Clarion–Clipperton Zone and implications for deep-sea mining baselines". This archive contains the processed analysis outputs, per-figure source tables and the code needed to reproduce the figures and quantitative results of the study. Using a five-model CMIP6 ensemble, the study evaluates when climate-driven change in abyssal temperature, dissolved oxygen, pH and upper-ocean particulate organic carbon export becomes distinguishable from natural variability estimated from preindustrial control simulations, and examines what this implies for the environmental baselines used to attribute deep-seabed mining impacts. Contents: figure-generation scripts and a shared style module; analysis scripts for the emergence, depth-sensitivity, contract-area versus protected-area, monitoring-duration and scenario comparisons; the locked analysis outputs behind every number reported in the paper; the exact per-figure input tables; a Python environment specification; SHA-256 checksums; and a manifest recording the provenance of each file. Raw CMIP6 model output is not duplicated here and remains available through the Earth System Grid Federation. Official International Seabed Authority contract-area and protected-area geometry is not redistributed pending reproduction permission; the derived regional summaries computed from it are included, so the spatial results remain reproducible from this archive.
