The dependent variable used in the travel cost analysis was the average number of visits to the site per year of diving experience.

However, given the nature of international dive travel, relatively few divers would have the resources to make several trips in a year, so a longer time period would be required to capture sufficient repeat trips. Also, as diving requires appropriate certifications, new divers would
