Marine bioluminescence on the surface: due to Climate crisis

Bioluminescence occurs when tiny organisms in the water are disturbed in some way. Although bioluminescence is used by creatures that populate the deepest abysses of the oceans, this phenomenon can also occur in coastal areas, close to beaches, although it shouldn't.

In fact, scientists explain that it is a symptom of climate change. Bioluminescence is mainly linked to marine organisms that are sometimes taxonomically distant from each other. In marine organisms, the light-producing organs are called photophores and are mainly present in fish, cephalopods, cnidarians of the order Siphonophora and other invertebrates living in the bathyal and in the abyssal plane as well as in numerous bathypelagic organisms.

The principle underlying bioluminescence is the same as that of chemiluminescence, in which some molecules, produced in an excited electronic state, emit part of their energy in the form of light radiation returning to the ground state.

Biochemical studies have shown that the mechanisms of light emission by living organisms are very varied and therefore, with good probability, this property has developed independently in the various biological groups.

Where can this natural phenomenon be found?

Bali and some Indonesian islands, when dense presence of plankton lights up when disturbed by boats, for example.

In Halong Bay, due to the large number of boats, it is not always easy, but if you get the chance it will be a fantastic sight. Cortez, in South Florida, is one of the last remaining small fishing villages in the Gulf. At Jolla Cove, San Diego, at night thanks to the crashing of the ocean waves.
Mosquito Bay is one of the places where the phenomenon of bioluminescence was first recorded.

Ton Sai, a beach loved by climbers and water sports enthusiasts, is one of them. The coast of County Norfolk, in Eastern England, is one of the best for observing bioluminescence, although this phenomenon can be observed almost everywhere along the coasts of the entire country.

In Toyama Bay, Japan, squid that usually live at a certain depth produce bioluminescence but occasionally the tide brings them to the surface.
