Our paper published in the recent issue of <I>Paleoceanography</I>
(vol 16 #1 pp 20-26) is a study of the effects of coral-algae symbiosis
on the skeletal chemistry and ultrastructure of <I>Porites. </I>Although
we focus on the implications for the interpretation of coral-based climate
data, our discussion of daily growth banding and day-night cycles in skeletal
accretion and crystal morphology may be of interest to some of you who
don't normally read this journal.
