Posidonie Photo | TrekEarth

Photographer’s Note

On the rock in the foreground you can see a layer of posidonie, a seaweed which has been brought to land by the waves.

More properly known as Posidonia oceanica, it is a superior plant and not an algae, presenting roots, stem, leaves and flowers, and it grows as far as about 30-40 meters deep. Its characteristic is to colonize the territory constituting real prairie, which is made possible by the nature of this plant, which has roots and rhizomes that develop both in the vertical (to reach the light) and in the horizontal.

The Posidonia has the merit of slowing down the wave moviment and the drift of the waves along the coasts, defending them in part by the force of erosion of the movement of the sea. This plant is considered a real lung of the Mediterranean, for the large amount of oxygen produced by its prairies (the island of Ischia, for example, is surrounded by it). This characteristic provides excellent living conditions for at least fifty species of fish, echinoderms, crustaceans and molluscs.

Often victim of pollution and destructive practices of habitat in the Mediterranean in recent years, the Posidonia is protected by a law and with a series of measures to protect the species. The Posidonia is a plant species endemic in Mediterranean, i.e. existing only in that habitat.

FRANCOIS

La Posidonia oceanica est une espèce caractéristique de la Mer Méditerranée, qui vit depuis la surface jusqu’à 40 m de profondeur. Il ne s’agit pas d’une algue mais d’une plante évoluée, qui a parcouru le chemin inverse de l’évolution, en retournant de la terre ferme à la mer. La posidonie se reproduit le plus souvent de façon végétative par bouturage mais, contrairement aux algues, elle développe des fleurs qui lui permettent de se reproduire également de façon sexuée pour former des fruits et des graines. La plante possède des racines et des feuilles rubanées, mesurant plus de 1 m de longueur. Formant de vastes herbiers, surtout sur fonds sableux, elle représente un patrimoine exclusif de notre mer et est protégée par plusieurs conventions internationales

ITALIANO

Più propriamente conosciuta come Posidonia oceanica, essa è una pianta superiore e non un'alga presentando radici fusto foglie e fiori, e cresce fino a circa 30-40 metri di profondità. Sua caratteristica è poi quella di colonizzare il territorio costituendo vere e proprie praterie, il che è reso possibile dalla natura di questa pianta, che presenta radici e rizomi che si sviluppano tanto in senso verticale (per giungere alla luce) che in quello orizzontale (per estendere la cosiddetta prateria).

La Posidonia ha il merito di frenare il moto ondoso e la deriva delle onde lungo le coste, difendendole così in parte dalla forza di erosione del movimento del mare. Questa pianta è considerata un vero e proprio polmone del Mediterraneo, per la grande quantità di ossigeno prodotta dalle sue praterie (l'isola d'Ischia, ad esempio, ne è circondata). Questa sua caratteristica assicura ottime condizioni di vita ad almeno una cinquantina di specie tra pesci, echinodermi, crostacei e molluschi.

Spesso vittime dell'inquinamento e di certe pratiche distruttive dell'habitat del Mediterraneo, negli ultimi anni le Posidonie sono state tutelate con una legge dello Stato e con una serie di misure che ne proteggono la specie. Le Posidonie costituiscono una specie di piante mediterranee endemiche, vale a dire esistenti soltanto in questo habitat.

manca solo l'odore della posidonia che marcisce in questa foto, per il resto sembra di essere li' talmente ben realizzata.
ottimo lavoro
Giorgio

Ciao Donato ,
A very fine coastal landscape , with an interesting subject , too . I like a lot the light and contrasts here , also the very natural colors . In Brittany , we get seaweeds to , but not like Posidonies . I've played on these ones on the beach in Corsica with my children , it was funny .
Regards
Denis

Ciao Caro Donato,

Una molro bella vista, asculto il rumore del mare. Una buno utilizo della luce dà bei contrasti e colori forte. Una belle profondità di campo anche con le rocce al primo plano.
Ti auguro una buona domenica,
Roger

Hi, Donato,
A very nice capture of the eternal water move.I like the colours and these blue waves white frothy crests.
It's appealing and inspiring.

darek1978 (11431) 2009-03-15 6:15

Hello Donato,
You were able to catch an incredible light. This is absolutely fantastic composition with beautiful colours. I think this is a very good picture for a cloudy sunday afternoon, which we usually have in Dublin.
Have nice sunday afternoon,
Best regards,
Darek

ellelloo (4923) 2009-03-15 6:31

Ciao Donato,
What a beautiful coastal landscape! A good POV and composition with several layers of interest. The light is gorgeous here and the colours are beautiful and warm, looking like taken later in the afternoon. Excellent depth and sharpness. Although the title and the message via your good note is about the Posidonia seaweed, my eyes are glued into the beautiful sea with its changing colours and the waves, which you can almost hear splashing into the shallow waters. Complimenti!
Saluti,
Lasse

gunbud (28121) 2009-03-15 20:01

Hi Donato,
Another stunningly beautiful seascape with the golden texture of the foreground rocks wonderfully complimented by the vivid blue sky and sea while it contrast brilliantly with the rolling white surf.
The colors are are perfectly clear and vibrant to go along with fantastically sharp details.
Wonderful note about the wonderfully unique sea plant.
Regards, Tom

Hi ingenua, this is wonderful and very wellc aptured from a lovely pov. the hues and the ambient textures are superb

fulvio52 (8314) 2009-03-16 4:19

Ciao, Donato.
A me queste sono vedute che ispirano e piacciono veramente un sacco. Paesaggio bello ed incisivo, senza fronzoli, un quadro assolutamente naturale su cui meditare... sembra quasi di sentire la brezza sulla pelle e il rumore delle onde che s'infrangono sugli scogli. Bravo, incondizionatamente! Ti auguro una buona giornata, a presto. Saluti carissimi,
Fulvio.

Silvio1953 (42617) 2009-03-16 4:43

Ciao Donato, nota interessante, non sapevo della funzione di questa pianta dal nome che richiama il Dio del mare, grazie, fantastica la vista delle coste della Sardegna, eh quant'è bella, bravo, ciao Silvio

carper (65524) 2009-03-16 4:49

paololg (14129) 2009-03-16 8:12

Ciao Donato,
a parte l'interessante nota naturalistica, la foto è apprezzabile non solo per la bellezza del paesaggio, ma soprattutto per l'infinita profondità che sei riuscito a dare all'immagine. Pregevole anche il senso del rilievo del mare e delle nuvole sull'orizzonte. Un bel lavoro da fotografo "navigato" :-) Bravo!
Ciao, buona serata!
Paolo

danos (33126) 2009-03-16 9:22

Ciao Donato,
a seascape view with a wild view and the white waves to cover the surface of the sea. Interesting the rock in the foreground as the view of the opposite coastline.Well done.

Have a nice afternoon,Danos

jemaflor (39689) 2009-03-16 11:59

Hi D,
Very lovely marine landscape, good pov and great effect with this light, good choice with this rock in the fg, perfect sharpness.

berek (28989) 2009-03-16 14:00

Ciao il mio amico Donato,
Bello paesaggio litoraneo. Gradico la luce ed i contrasti ed i colori naturali. composizione incorniciata pozzo.
abbia una settimana piacevole.
Burak

Greg1949 (8515) 2009-03-16 14:13

Donato, I am pretty sure I have been here but even if I haven't is a place I would like to see again. Your capture is a awesome and the detail is wonderful. Great capture.

Greg

clio (23003) 2009-03-16 14:47

Ciao Donato,
Mi piace molto osservare le ondulazioni dei posidonia con una maschera, poiché si possono trovarli molto vicino alla riva nei posti in cui le ancore delle barche non le strappano. È sempre il segno di un'acqua poco inquinata.
Colori splendidi e molto bello dialogo tra le piccole nuvole e le creste delle onde nella tua foto.
Buona serata
Diane

diomed (4541) 2009-03-16 17:21

Ciao Donato,
la tua ricca ed esauriente nota completa un'immagine ottimamente composta, con un bel cielo, belle onde spumeggianti, grande profondità e definizione.
Buona serata
Antonio

ChrisJ (70443) 2009-03-16 20:19

Hi Ingenua

A superb seascape, with wonderful colour & saturation. Good sharpness & graphism of the dark rocky fg headland, against the lighter toned sea. Tfs!

fanni (8811) 2009-03-17 2:55

Ciao Donato,
if it were not for your explanation in the Note I would never think that it's seaweed on the rocks!
Concerning the image in general, I like the way the distant clouds match the spindrift (which is mainly in the FG).
Beautiful landscape! good rich colours.
Warm regards,
Elena

Gerrit (36157) 2009-03-17 3:48

Hi Donato,
great light and colors in this very well composed coastal landscape.
Great definition and quality,
regards, gerrit

Muse (31049) 2009-03-17 3:59

Ciao Donato,
Thanks for the french comment! It's very interesting and the compo is really beautiful.
Beautiful colors and light. See and sky seem to make only one. A landscape which we do not grow tired of admiring.
Best regards
Denise

Miha2ou7 (4937) 2009-03-17 6:43

Hey Donato,

A motive seen often in your photos, but always sort of from a different perspective. Another nice shot. I especially like the defined clouds in the background, although the picture as a whole seems just a bit on the "dark side". Otherwise, it`s thoughtfully composed. Too bad the water is freezing.

Best regards.

polpo56 (8084) 2009-03-17 16:11

Ciao Donato,
un paesaggio selvaggio e naturale, esaltato e valorizzato grazie all'uso sapiente della composizione.
Lo sai che più dell'80 per cento dell'ossigeno del pianeta è prodotto dalle piante acquatiche, tra cui la Posidonia?
Un abbraccio
Ludo

BelCan75 (2420) 2009-03-17 18:28

Hello Ingenua,

This is an amazing shot with great light, beautiful bright colours and details. Wonderful POV with the rocks in the foreground creating good depth. Great work!

Greetings,
Ann

Fellini (4962) 2009-03-18 2:48

Un gran bel landscape, cielo e mare da cartolina...sembra una foto di viaggio, non sembra neppure Sardegna, tutto molto ben regolato, ineccepibile, quasi maniacale.
Interessante la nota sulla Posidonia, la sua funzione è similare alla Mangrovia delle isole tropicali.

Sai una cosa, perchè non provi a fare qualche join...qualche panoramica ampia, non mi sembra che ne hai mai postate, mi sembra che luoghi come questo si prestino a visioni 'grandangolari', come quelle che ha postato stefanocer....
Buona giornata
Ale
PS: mi sono guardato in giro ... ma alla fine tutti i vari amici qui su TE hanno cambiato macchina fotografica...Ergo siamo solo noi due con la macchinetta scadente!! siamo dei sopravvissuti... :-))

pablominto (41200) 2009-03-18 4:12

Hello Donato,

The rough sea adds life to this fine composition!
Excellent colour reproduction with the different shades of blue in the water...
The point of view works well and the rocks in the foreground adds depth to the composition!

Greetings,
Pablo -

Cricri (43616) 2009-03-18 9:00

Un paysage qui me laisse rêveuse, la mer aux sublime couleurs et son côté sauvage super bien présenter içi, magnifique image de la Sardaigne

Ciao Donato
Forse qualcuno ha un virus in posta elettronica.l
Non riuscivo a scrivere.
In effetti manca il mio commento, non vorrei che la fretta ne abbia tagliati altri.
Per la foto come dicevo stamani è grande opera meritoria questa nota e foto, che assieme dimostrano che il mare va tutelato dall'imquinamento e dalla pesca a strrascico
Complimenti

PixelTerror (86691) 2009-03-18 22:48

Hi Ingenua,
Nice coastal landscape with a luminous impression on the foreground but there is a little halo over the hill telling about your PP like some shadows/highlights adjustments.
Have a nice day JY

COSTANTINO (23111) 2009-03-19 11:36

Ciao Donato,

Una foto ben composta e realizzata con ottimi colori,bel contrasti e luce,
belli colori delle onde ed un cielo fantastico,nota molto interesante,
complimenti amico mio,

zeca (20026) 2009-03-19 22:42

Ciao Donato!
The framing is very clever, well using the foreground rocks to have a nice depth. Of course that the view is beautiful, and you've got excellent lights to create this very good colours. Well taken!
Regards,
Zeca

trekks (14334) 2009-03-19 22:43

hello Donato

Obviously the sea wave action is strong enough to wash the sea weed ashore. The exposure of rock is also a testimony of strong wave action.

Good capture of the coastal scenery with such a bright light. Always a wonderful view of blue sea when the blue sky is up like this one.

tfs, bill

Kielia (8691) 2009-03-20 10:56

Hi Donato,
a great contribution to “learning about the world…”. Your interesting note is accompanying a wonderful impression of this seaside. The light and the colors are excellent. But most of all I like how you have captured the atmosphere so that one can even smell the salty air. TFS!
Warm regards
Harriet

anto95 (1820) 2009-03-22 14:14

Hi Donato,
This is very great moment for take a very nice picture.
Antonello

Floydian (30970) 2009-04-04 6:57

Hello Donato,

Some of your pictures have a dark mood with lack of real good light, but see this one, this is more how i like to see them. Fresh warm light lies over the rocks in front and even the water shines. The blue on top with clouds is another detail what makes this one stand out against some of the others. The F4 i don't understand, but maybe you had no tripod with you...
anyway, a bright, colourful and warm picture which i really like....well done.

Regards,

Henk

BilboCA (734) 2009-08-14 20:22

Hi, Donato,

Very interesting story about this plant.

And really an excellent photo in many respects. The lighting is very fine and combined with the clear skies produces a nice palette of blues, greens and browns that you have effectively captured.

I like your main compositional treatment of the foreground rocks separating water to the left and the right using a diagonal orientation. It complements nicely the split horizon between water on the left and the land on the right.

I've learned (especially here on TE) to be attentive to the edges of the frame and for your photo I think it might have been a good tactic to not cut the house that appears along the right edge; either all in or all out would have been a better choice, I think. But this is a very small criticism for an otherwise excellent photo. And clearly (from your high score) many TE people think similarly!

Regards,
- William
