(12) The Monitoring Method.
Tape marking 20 meter transect line to be monitored.
Digital video camera in U/W housing.
40 cm wand for gauging distance from substrate.
 A Digital Video Camera is used to record coral reef data for analysis.
At each monitoring site 20 randomly distributed transects were monitored.

The video method :
1)Minimized the time required to collect data underwater.
2)Reduced the requirement  for data collectors to be experts in coral
identification
3)Provided a permanent record of the collected data for
•Review
•Distribution and consultation
•QA/QC
•Public Awareness
•Decision making
4) Although building on the CARICOMP method, the decision was taken
 to adopt digital video technology. The two methods used to monitor the
same reef site in Cayman,  have been shown to produce results that are
statistically indistinguishable (Woodley, Pers. Com, 1999).
