Turbid water generally affect the biodiversity badly.
Well I guess, a phytoplankton bloom increases turbidity, especially in eutrophic waters. And the other way of the causal chain is also possible, in waters with high sediment induced turbidity, phytoplankton may be affected. However, I think submerged macrophytes are generally more affected by turbidity than phytoplankton.
Extinction coefficient reduces the penetration of solar radiation and reduces phytoplankton proliferation.
The blooming of phytoplankton are related to many factors, the main factor are the availability of P and N. Turbidity reduce the growth of phytoplankton.

Location has not been mentioned here. Even though water is turbid, the phytoplankton bloom may be due to excess availability of nutrients by river discharges or upwelling in the coastal waters. In general turbidity affects the growth of phytoplankton or any aquatic organisms. Thank you.
Water turbidity can be a direct consequence of the phytoplankton bloom (i.e., think of red tides)
Of course. Living organic particles are part of total suspended matter. Thus, blooming phytoplankton contribute significantly to water turbidity. If question was more targeted to know whether turbidity could enhance phytoplankton growth, the answer is more ambiguous. It depends on what is causing turbidity. It is likely that suspended particle leach needed phytoplankton nutrients, but if turbidity is high it will partially block light penetration. In general what happens is that phytoplankton grows several days after turbidity peaks.
Plankton bloom is largely due to the rapid and marked increase in phytoplankton abundance filliped by excessive presence of nutrients, sunlight and changes in seawater temperature. I think that phytoplankton bloom could directly influence the turbidity of water.
Yes they have relationship. Initiation and sustenance of phytoplankton bloom depends on mainly two factors i.e., Light and nutrients. Though turbid water may provide more nutrients, consequently it reduces the light penetration in the water column, thereby reducing phytoplankton growth. Lack of light availability would stop photosynthesis and lead to hypoxia which will affect the biodiversity. On the other hand, collapse of a strong phytoplankton bloom might increase the turbidity of the water body substantially.
here is a specific example

Turbidity through phytoplankton is a temporary phenomenon,as individual cells have a short life span.Phytoplankton do cause turbidity, & the cells have the ability to garner more of the light if it is getting minimal. If the waters are charged with P, then the bloom may be prolonged,lengthening turbidity time.
