Story: Sea floor geology

Hikurangi Channel

Hikurangi Channel

Mud and sand from Kaikōura and Cook Strait canyons are carried by fast, muddy flows called turbidity currents. Most turbidity currents spill out of a gap 1,400 kilometres along the channel, where the current known as the Ocean Conveyor spreads the sediment into a fan. Some currents continue up to 600 kilometres further across the deep ocean floor.
