Cook Strait currents

Cook Strait currents

Cook Strait is not only a bottleneck for wind; as this map shows, tidal currents pour through the narrow gap between the North and South islands. They scour the sea floor and transport gravel back and forth. This makes a harsh environment for cables lying along the seabed. The cables are armoured to protect them from abrasion.
