This replication package contains links to the primary datasets used in Pratson, L.F., Assessing impacts to maritime shipping from marine chokepoint closures, Communications in Transportation Research. It also contains the secondary data sets generated from the primary datasets and the MATLAB code developed to create the secondary data sets. The primary datasets are the ORNL 2000 Global Shipping Lane Network GIS shapefile, and HS92_202102 version of CEPII's 2019 BACI Trade Flow data. The secondary datasets consist of three Excel files: (1) MarineChokepointBlockagePaperShipLaneNetworkNodeEdgeTable.xlsx, (2) MarineChokepointBlockagePaperChokepointScenarioTables.xlsx, and (3) MarineChokepointBlockagePaperMasterTradeAndChokepointTables.xlsx. The code used to produce these consists of eleven MATLAB scripts. See included replication explanatory file for further details.
