Importance of critical depth
WitrynaSverdrup's “critical depth” is commonly associated with the initiation of the spring bloom in clear oceanic water. This concept originated, however, from observations made in a murky inshore location, the Bay of Fundy (Gran and Braarud, 1935).There, elevated non-phytoplankton light attenuation, in combination with strong tidal mixing, was likely …

WitrynaCritical depth is a quantity of fundamental importance to understanding the flow characteristics. If the actual depth is greater than critical depth, then the flow is considered "subcritical". Subcritical flow is "slow flow" … Witryna2 mar 2024 · The magnitude of critical depth depends only on the discharge and the shape of the channel, and is independent of the slope or channel roughness. Thus, in any given size and shape of channel, there is only one critical depth for a particular …
In biological oceanography, critical depth is defined as a hypothetical surface mixing depth where phytoplankton growth is precisely matched by losses of phytoplankton biomass within the depth interval. This concept is useful for understanding the initiation of phytoplankton blooms. Witryna9 kwi 2024 · Critical thinking is a skill that is essential for success in both personal and professional life.
