MedClim analysis code for Mediterranean thermohaline acceleration analysis

Analysis code for the study "Observational evidence for accelerated warming and salinification propagating into the deep Mediterranean" (Terzić & Vilibić, Geophysical Research Letters, 2026). The archive contains the tracked analysis and plotting scripts of the MedClim workflow: 62 files covering preprocessing and quality control of the source datasets, the spatial framework and coastal/river masks, depth-bin averaging and eligible-cast sampling support, seasonal climatology construction, monthly time-series construction and deseasoning, trend and acceleration estimation, the robustness and sensitivity analyses, and generation of the manuscript figures. A README describes the workflow stage by stage and maps each main figure to the script that produces it. Machine-specific paths have been rewritten relative to the repository root, so the scripts are portable. Large raw inputs and derived products are deliberately not redistributed here: the Argo and SeaDataNet source data are publicly available from their original repositories and are cited in the manuscript, and the cleaned regional Adriatic datasets are deposited separately (doi:10.5281/zenodo.20345373). This version corresponds to the accepted manuscript.
