Story: Sea floor geology

Sediment plumes

Sediment plumes

Land is a major source of marine sediment. Rivers off the South Island’s east coast carry huge quantities of sediment out to sea, discharging the muddy plumes (aqua coloured) visible in this satellite image. Currents carry the material along the coast and deposit it on the sea floor. White areas are clouds.
