The oceans are not well mixed. Bodies of water have different temperatures, salinity and clarity, and often do not mingle, but lie on top of one another. The plume of sediment in this photograph is flowing from the Waimakariri River into Pegasus Bay, north of Christchurch. The fresh water from the river mouth floats out on top of the denser sea water.
