What causes tidal overmixing in estuaries?

Oysters generally settle at right angles to tidal currents. These currents:

It is common for negative estuaries to be:

Seagrasses are important in all the following except:

Even though estuaries support large numbers of organisms, there are relatively few numbers of species that live in estuaries. Why is this the case?
