Yes, there is software for this kind of thing. There is MacDendro, available from Rejean Guay (sorry I don't have the address handy but I can look it up if you want). I believe it is fairly expensive, but is readily available and works well. Or there is our own product, DendroScan. It is designed for tree-ring analysis, but has been used quite successfully on other "growth rings" including varves and polar bear teeth. It is relatively cheap, and will also do the job very well. The hitch is that it is not yet quite available - we are doing the final edit of the manual now, and expect to be publishing this summer. We expect it will be marketed through UBC Press for about C$100/copy (~US$75), including the software. If you can wait that long, fine. Else drop me a private e-mail and we'll see what we can do. If there are only a few samples, we could run them for you from good quality photgraphs. | Dr. Ian D.
