Previous investigations by the senior author in the Caribbean have been reported at earlier Caribbean Geological Conferences (Oostdam, 1983, 1989, 1992).
The principal new method in this study was the circulation of a brief
questionnaire/contest which asked participants:
Some 1,550 questionnaires were mailed out to 25 islands as follows:
Six sets of 30 questionnaires were returned "undelivered" by Postmasters
and some 20 others could not be delivered in time. A total of 85
responses was received as of the end of September 1995 representing about
6.5% return.
Returns from professionals were highest (8%) and from postal patrons lowest (4%). Considered by island nations, the largest number of responses came from Anguilla (11 or 26% of those mailed to Anguilla), the USVI (9 or 16%), St. Kitts & Nevis (8 or 16%),
Puerto Rico (7 or 23%) and Barbados (6 or 6%).
No responses were received from any of the four major French speaking
islands, except one from St. Martin. Seven islands only produced a
single response each.
The responses were tabulated and graphed and an interesting "calibration exercise" (Figure 5 and Figure 6) allowed intercomparison of 'general' responses with those of an expert (Dr. Gillian Cambers) who kindly provided input for 12 individual East Caribbean islands.
