This project develops a standardized pipeline to compile, clean, and restructure tuna catch and effort datasets from multiple Regional Fisheries Management Organizations (RFMOs).
data/:
data/raw: contains original datasets retrieved from RFMOsdata/processed: contains cleaned data from various RFMOs in a standardized format
processed/01_bound: contains bound RFMO data sets at various resolutionsdata/output: contains harmonized RFMO datasetsscripts/:
scripts/01_standardizing: contains scripts that clean RFMO datascripts/02_processing:
02_processing/01_bind_data: contains scripts that bind RFMO data and detect overlapping cells02_processing/02_harmonize_data: contains scripts that harmonize RFMO datascripts/03_content:results/:
