Monitoring and Surveillance Options
A variety of techniques exists for surveying subtidal biotopes.
Different techniques provide different types and quality of information. The choice of
method(s) to be used will therefore depend on the type of data required, and on the
purpose of the survey, which may be either initial mapping and faunal characterization
over a large area, or repeated monitoring at a smaller spatial scale. The availability and
cost of the equipment required will also be a factor.
This chapter will review the methods available, summarize the
advantages and disadvantages of each, and discuss examples where particular techniques
have been applied to the study of brittlestar beds.
It is worth noting at this stage that all these monitoring techniques
require appropriate training and practical expertise to be employed effectively. In common
with most other field investigations in the marine environment, success is usually also
dependent on favourable weather conditions.
