Carol Simpson asked about tide tables. I haven't kept the messages on this sent from time to time on Conch-L, since I work with fossils myself. Typing "tide tables" into Alta Vista yielded almost 4000 Websites, mostly for local tide tables. This is the first one that looked international. This is not a recommendation by the Geological Survey of Alabama, or even by myself, since I haven't tested it out: http://www.hydro.gov.uk/Tidebook.htm Andrew K.
