I want to draw your attention to our paper published recently in GRL 
which demonstrates a relationship between coral skeletal chemistry and 
tidally-induced changes in water level height on weekly (and longer) 
timescales.  The link, we believe, is via tidal modulation of symbiont 
photosynthesis (e.g. Anthony and Hoegh-Gulberg 2003); the effect of 
photosynthesis on skeletal chemistry having been demonstrated 
independently.   The full reference is:  Cohen AL, Reves-Sohn RA. (2004) 
Tidal Modulation of Sr/Ca in a Pacific Reef Coral. Geophysical Research
