Calcification rates in corals are discussed also in Chapter 2.5. 

The zooxanthellae increase the calcification rate by removing H2CO3 and CO2 resulting from the formation of CaCOa (Goreau, 1959). 

Calcification rates for reef flat and seaward zones are shown in Table 2.5.7 and may be compared with the results of metabolic CO2 turnover for the same locations in Table 2.5.3. Whereas the organic activity varied to a moderate extent, the results for net carbonate deposition are remarkably similar for the different environments. The variations in community structure seem to have no effect on this activity and there is no correlation with latitude. While the number of reefs represented is small, it covers a rather wide range of reefal types and it is suggested (Smith and Kinsey, 1976) that there is some factor, as yet not understood, setting a ceiling on the calcification rates in these peripheral seaward zones regardless of the development of the community structure. The potential for positive physical...

The thermal denaturation temperatures for glutaraldehyde-treated CEM, pretreated with EDTA and ethanol, have been reported to be all in the narrow range of 95-105 C. This suggests that these pre-treatments did not affect the stability of CEM. However, even within this range, there was a difference between the untreated CEM, that pre-treated with ethanol only and that pre-treated with ethanol and EDTA. The study found that sequential treatment with ethanol and EDTA decreased the calcification rate of CEM and this has value in the fiiture therapeutic strategy of BHV application.
