Source-Destination Marine Biosecurity Risk Quantifications

Posted on 2022-12-02 - 09:53 authored by Mimi Tzeng

This collection contains files related to calculating voyage-related marine biosecurity risk from computer-generated maritime vessel paths between pairs of Marine Ecoregions Of the World (MEOW) ecoprovinces (Spalding et al. 2007). The physical length of the path is used to calculate voyage duration risk. The cross-latitudinal extent of the path is used to calculate voyage path risk. In addition, environmental similarity risk for each pair of MEOW ecoprovinces is calculated from environmental distance (previously calculated in Tzeng 2022). 


The final dataset consists of six matrices that each contain one of the following variables associated with each possible pair of MEOW ecoprovinces: environmental distance, physical distance in meters, cross-latitude distance in decimal degrees, environmental similarity risk, voyage duration risk, and voyage path risk.
