Biopluminescent waves decorate Allepey shoreline

Alappuzha | As  darkness off dusk was descending  on Alappuzha seashores  yesterday, it was found as if the seashores  were decorating with thousands of  fluorescent lamps, when the waves splashing on the shores with glowing sea of blue stars.
The rarest of rare phenomena occurred in the coast Monday night at around 2200 hours, which was stunned some youths, who were there at that time.
The youths said that they felt that  as if scores fireflies landing at the shore, when the blue waves lashing on the shore making a feeling of decorating the shore with fluorescent bulbs, a magnificent which would never witness to all at any time.
According to National Oceanographic Institute Principle Scientist Dr P K Dinesh Kumar, though the real fact was not yet ascertained, it would happen such phenomena because of two deep water marine organisms like Ostorcodes or Dinoflagellate.
With the preliminary observation it was suspected that the phenomena would 90 per cent be because of Dinoflagellate, which was found in deep waters, Dr Kumar said.
Most probably it could be a large colon of noctiluca millaris, a species of Dinoflagellate that exhibits bioluminescence, he added.
The phenomena  might be occurred because these organisms got conducive atmosphere like good sunlight, nutrients and  mix salt water, he said adding that since the Arabian sea was turbulent these tiny marine creatures come to the shore along with huge waves.
Since these creators were food for fishes, their proliferation might be indicating that the fish wealth was also decreasing in the area, he noted.
Pointing out that this kind of unusual phenomenon was a clear cut indication and warning about climate change, Dr Dinesh stressed the need for a long observation and study to collect data in order to overcome such situation.
Stating that there were no cause for panic or harmful to the people,  he said adding that the Arabia sea has witness a radical shift in the phytoplankton blooms which previously comprised mainly diatoms the unicellular photosynthetic organisms.
There  have been replaced by  the present Noctiluca (dionflaggettalte ) blooms, These outbreaks are facilitated by the oxygen deficient waters and  the extraordinary ability of Noctiluca of proliferate in low oxygenised conditions. Recurrence of Noctiluca  in the long term could disrupt the traditional diatom sustained food chain to the determent to the regional fisheries and long term health of the coastal marine system.
Theres a lot lurking beneath the oceans dark abyss, but light might be one of the most unexpected. In actuality, a large number of sea creatures are bioluminescent, which means they emit light from a chemical reaction occurring within them. Bioluminescence can be found in bacteria, fish, jellyfish, octopi, squid, and sea wormsand most of them are deep-sea dwellers.
However, the most commonly seenand arguably the most awesomebioluminescent marine organisms are dinoflaggelates. These one-celled protists, 90 percent of which are marine plankton, have a very striking feature: when disturbed by a predator or a wave, they give off a bright blue light.
Fluorescent plankton  known as dinoflagellates  are sea creatures that are barely visible to the naked eye and are commonly referred to as algae. Whip-like projections called flagella allow them to swim fast while internally they produce their own form of bioluminescence. And when they occur in great numbers, they can form intense and spectacular phosphorescent blooms around beach areas as they become agitated by the turbulent surf.
