1 апр. 2010 г. · The Critical Depth Hypothesis formalized by Sverdrup in 1953 posits that vernal phytoplankton blooms occur when surface mixing shoals to a depth shallower than ...

The critical depth hypothesis (CDH) is a predictive criteria for the onset of phytoplankton blooms that comes from the steady-state analytical solution of a ...

The critical depth is the depth below the sound channel axis at which c equals the near surface maximum. The depth excess is the vertical distance between the ...

In biological oceanography, critical depth is defined as a hypothetical surface mixing depth where phytoplankton growth is precisely matched by losses of ...

One way to define the critical depth is the depth is the depth above which depth-integrated daily gross photosynthesis equals the depth-integrated respiration, ...

At its heart the Critical Depth Hypothesis, as mathematically formulated by Sverdrup (1953), asserts that mixed-layer phytoplankton biomass is sustainable if ...

The critical depth, denoted by yc, is the flow depth at a section where the flow is critical. In a given open channel, the critical flow may not occur at all.

We show that the critical depth criterion is a necessary, but not a sufficient, condition for the initiation of a phytoplankton bloom. Finally, we reformulate ...
