Directory structure

  • analysis provides the scripts and notebooks for processing Lagrangian trajectories. It includes scripts to identify enrichment and depletion regimes (dubbed 'events' here), compute total $\Delta$DIC, and create the plots from the manuscript. It also includes an analysis of the Eulerian DIC changes and surface biases. Note that NASTMW is sometimes referred to here as EDW (Eighteen Degree Water).
  • environments contains the python environments that were used.
  • jobs contains bash scripts that execute relevant code to the HPC used for this study.
  • observations contains a notebook to plot the tracks from observations
  • preperation contains scripts and notebooks used in preparation for the simulations. It includes model-data comparison notebooks, which were used for selecting NASTMW criteria. It also includes a NASTMW/EDW mask creation script, a climatology computation script, and a script to precompute the vertical mixing fluxes.
  • simulations contain the Lagragian simulations script. Simulations are initiated from the submit_job_EDW_sim.sh script in the jobs directory.
  • tools creates tools for idenitfying enrichment and depletion regimes ('events'), plotting, and preprocessing $\Delta$DIC timeseries.
