SCIETIFIC DIVING
The equipment used varies in this field,
and is generally chosen based on cost,
effectiveness, availability, and risk
factors. Open circuit diving is often used
because it is widely available and cost
effective.
Training standards vary around the
world, are generally higher than those
for entry-level recreational diving, and in
some cases are identical to commercial
diver training. There are few
international agreements that make it
easier for scholars from different places
to work together on projects of common
interest, by recognizing minimum levels
of competency acceptable to both
parties.
Some diving activities to support
scientific research
Sampling: Scuba diving is a useful
method for taking samples from specific
underwater locations.
Quantitative survey and monitoring:
Quantitative surveys and assessments
may include quantitative descriptions of
biotic populations, the distribution or
abundance of a species, group, or other
feature, or correlating topography of the
sea floor.
Behavior of marine life: Scientists study
the behavior of marine creatures
through direct observation, video, or
photography.
Environmental Impact Study: Diver
monitoring can be quick and effective in
determining the scope and extent of
environmental disturbances, and
samples and measurements can be
taken as their effects are observed.
Mapping: A live survey by divers may be
necessary or preferred, depending on
what will be mapped on the map.
