Pelorus Sound
A further factor affecting the hydrodynamics of Pelorus Sound is wind. Winds in the area are generally strong and are channelled by the steep topography. Wind stress acting on the surface generates currents, which have not been well described. The wind stress also generates turbulence, which causes the surface fresh water to be mixed down and results in a brackish layer typically 5 to 15 metres (16 to 49 ft) thick. The interface, called a pycnocline, between the brackish near-surface water and the denser water below supports internal wave motion.
