Description

It was an amazing sight of seawater with two different colours which seemed to change at a certain boundary, giving a sense of two different water bodies.
Oceanographers monitor the ocean's colour as doctors read the vital signs of their patients. Colour seen on the ocean's surface reflect what's going on in its vast depths.
NASA oceanographer Gene Carl Feldman points out, "The water of the ocean is not blue, it's clear. The colour of the ocean surface for the most part is based on depth, what's in it and what's below it."
Depth and the ocean bottom also influence whether the surface appears a dusky dark blue. Oceans with high concentrations of phytoplankton can appear blue-green to green, depending on the density. Greenish water may not sound appealing, but as Feldman says, "If it weren't for phytoplankton we wouldn't be here." Phytoplankton serve as the base of the food web and primary source of food for zooplankton, which are tiny animals eaten by fish. The fish are then eaten by bigger animals like whales and sharks.
It's when oceans become polluted with runoff that the amount of phytoplankton can escalate to unhealthy levels. Phytoplankton feed on the pollutants, flourish and die, sinking to the bottom to decompose in a process that depletes oxygen from the water.
The natural phenomena of turquoise swirls I see from North Head lookout Sydney, Australia are likely coloured by a bloom of coccolithophorids mixed with dark blue of Tasman sea !
This has nothing to do with pollution and its great for the ocean as the good organism blooms !!! But only scientist under the microscope would be able to establish the exact type of bloom of coccolithophorids.
