Ocean Health Index assessment of global EEZ regions

Anatomy of the file structure

General information about file structure is here: http://ohi-science.org/manual/#file-system-organization

This includes files for the OHI global assessment for eez boundaries:

  • eez (scenarios: 2012 - current): OHI for 220 country/territorial EEZ regions, this is typically considered the "OHI global assessment"

Additional files/folders include:

  • eez_layers_meta_data: Database for the data layers (data sources, names, etc.) and functions to create different data formats
  • global_supplement: documents and code to create methods document
  • global (2015-2017): Post assessment analysis and visualization of data
  • calculate_scores_??.R: These files provide the code to calculate scores for the corresponding OHI assessment (the calculate_scores.R for the eez regions is located in the eez folder)
  • layers_??.csv: These files provide the location of the data layers used to calculate the OHI assessments. This file is created by data and functions in the eez_layers_meta_data folder, and they are used by calculate_scores_??.R.
  • other files can be ignored

Important files within the "eez", "antarctica", and "high seas" folders include:

  • calculate_scores.R: code to calculate scores
  • layers.csv: provides the location of the data layers used to calculate the OHI assessments. This file is created by data and functions in the eez_layers_meta_data folder
  • scores.csv: The OHI scores
  • layers: All the data layers used by the OHI models to calculate scores
  • conf: Files that are used to set up the OHI model parameters
    • config.R: define model parameters, weighting files, etc.
    • functions.R: functions used to calculate goal/subgoal status and trend scores
    • goals.csv: list of goals and corresponding weights (also where status years are defined for each assessment year)
    • pressures_matrix.csv: Weights for each pressure layer and goal
    • pressure_categories: Defines the pressure category for each pressure layer
    • resilience_matrix.csv: Indicates which resilience layers affect which goals
    • resilience_categories: Defines the resilience category for each resilience layer
    • scenario_data_years.csv: Links the scenario year to the corresponding year of the data for each data layer
