To what extent are spectra
controlled by stirring and mixing?
A theory is
required to underpin the analysis and comparison
of plankton
and “inert” tracer spectra.
Such a theory needs to
relate structure in biological fields
and velocity fields at all
scales.
A
pre-requisite of this is a suitable model of turbulent flow.
Several user-friendly
options have been used.
All rely on
cascades – the conservative transfer of a property
from one
scale to the next,
from large
scale to small scale.
