(<6 mg/m 3 ) a drastic reduction in the biomass of the higher trophic levels is
observed, but no stable pattern is noted either with respect to the waters little sat-
urated or those oversaturated. Accordingly, for the region as a whole these zones are
observed to be travelling apparently due to hydrodynamic processes on a non-stable
pattern without causing any perceptible damage to the entire community.
