[Coral-List] Coring method

[Michel Claereboudt]

Can someone guide me to information for drilling cores in corals
i.e. types of drill (manufacturer?), type of bits, length of bits, 
method, tips and tricks...

The purpose of these cores is to assess changes if any of growth rates 
in the last 50-100 years in the Arabian Gulf and Gulf of Oman. They 
will be sliced and Xrayed. There is a lot of litterature on the second 
part of the method (xray, densitometry, fluorescence etc...) but 
nothing (so far) on the actual drilling process.

Thanks,
