Mare the Sea with its Secrets in the Depth

Mare the Sea with its Secrets in the Depth

Everything is enlightened by Charlotte Elisa Schaum

in his novel “Le Rayon Vert (The Green Beam)” described Jules Vernes A phenomenon that shows a broader popularity at the latest by the Pirates of the Caribbean last part received: The green glow.


What used to be a sign of the return of a beloved (or feared) soul to the seafarers from the underworld is indeed a very rare natural phenomenon that enjoys general popularity among oceanographers. On the open sea or on coasts with only low air pollution, the red light of the sun close to the horizon becomes its Color components, also called spectral colors, disassembled. The color components of the setting sun are red, green and blue, with the red-orange light in the middle and surrounded by a greenish-blue border. If the sun continues to set, the red part disappears first and finally completely. However, blue light is scattered so strongly in the earth’s atmosphere that it is hardly visible as such. What remains is green, and for a few seconds the sky shines in surrealistic splendor like a dali It couldn’t have conjured up better on the screen. Depending on the air composition, however, the interaction of refraction and reflection changes, so that a violet or blue light can very rarely be observed.

At sunset, the sun's light is broken down into its spectral colors

Has the sun set, a multitude of shining organisms

A variety of shining organisms begins to rainOnce the sun has set, a multitude of shining organisms stir in the sea, which turn night into day. bioluminescence – The ability to create light – is widespread in the sea. The best known are probably the microscopically small single-celled protozoa that are called dinoflagellates. The peculiar naming is either derived from the Greek, which is translated as swirling and well describes the movement of these unicellular organisms, or is an ode to the nature of the armor of the algae, which bears remarkable resemblance to dinosaur skin. Dinoflagellates, for example, are called Noctiluca scintillans (the nocturnal lights) and Pyrocystis fusiformis (fire bags), and send continual light signals when touched by water turbulence or passing fish and other sea creatures off. Since these protozoa are by no means hermits and individuals, but rather appear like thousands of them, the whole wave or the water surrounding the fish then begins to shine greenly. In the deep sea, of course, there is eternal night – with a few exceptions in those isolated places where the earth’s slabs are drifting apart from me and the hot, red-hot interior of the earth pours into the sea. Resourceful organisms shine here, especially in green and blue, more rarely in red. Jellyfish, sea cucumbers, crustaceans, fish, snails and bristleworms send messages like from another universe. At a depth of more than 5 kilometers, it flashes, glows, flickers and shimmers, reflects, absorbs, and disperses it for reasons that do not lack a certain drama. It’s about eating and being eaten, about love (or at least dating and continuing the species), and often about life and death.
If you can’t shine yourself and don’t keep luminous roommates, you’re left behind, remain inexperienced in the dark – and probably hope for enlightenment.
