Cross shore and along shore larval distribution and settlement along the south west coast of South Africa.

Theories suggest that invertebrate larvae behave as passive particles in the water column and therefore are dependent on water movements, which are to an extent affected by along shore and cross shore winds, to disperse and return to the shore. My project is aimed at understanding the effects of Easterly and Westerly winds on the dispersal, distribution and settlement of invertebrate larvae along the south west coast of South Africa. Physiological tests will be performed on the larvae to better understand their environmental limits to larval survival, settlement and recruitment.
