Murazzi a Venezia — The fortifications that protect from the sea

I Murazzi sono massicci muri in pietra d’Istria costruiti dalla fine del XVIII secolo dalla Repubblica di Venezia per difendere le aree abitate della laguna dall’erosione del mare. Sono divisi in tre sezioni: la prima è situata sull’Isola del Lido, la seconda sull’isola di Pellestrina fino a Ca ‘Roman. La terza sezione, sulla costa di Sottomarina, tra la Rocca di San Felice e il centro città, per una lunghezza di 1200 metri. Nella foto a fianco I Murazzi di Pellestrina travolti dalla mareggiata del 1966.

MURAZZI IN VENICE #murazzi #tempodacqua #thetimeofwater

Murazzi are massive Istrian stone walls built since the end of 18th century by the Republic of Venice in order to defend the lagoon inhabited areas against sea erosion. They are divided in three sections: the first one is situated on Lido Island, the second one on Pellestrina Island up to Ca’ Roman. The third section, on Sottomarina coast, between San Felice Stronghold and the city centre, for a length of 1200 metres.

The war of Chioggia caused the total destruction of Sottomarina, which became an uninhabited land, without any protection from the sea and subject to numerous floods. Only in the 17th century the rebirth of the town started, thanks to the building of the Murazzi. The walls in San Felice Road were more than 5-kilometre-long and 300 metre wide. They were made of squared stones, in particular Istrian stones and they were erected on the stilts coasts of Pellestrina and Sottomarina. Nowadays the Murazzi of Sottomarina are about one kilometre far from the sea, this allowed the development of seaside tourism on a large scale. The Murazzi connect the whole Venetian coast, especially the outside islands, just leaving three harbour entrances thanks to which the lagoon’s water does not die.

Tempo d’acqua sulla luna — The time of water on the moon

Che sulla Luna ci sia l’acqua si sa da dieci anni. Nel 2009, la sonda spaziale LCross (Lunar CRater Observation and Sensing Satellite) della NASA rilevò la presenza di acqua – sotto forma di ghiaccio – nel Polo Sud della Luna. O meglio il razzo che spingeva la sonda LCross, nell’impatto con il polo Sud della Luna, mosse detriti nei quali la sonda riuscì a individuare acqua in grani di ghiaccio. Recenti studi autorizzano a immaginare, oggi, che possa esserci una grande quantità di ghiaccio nella parte sempre in ombra del satellite. Non si tratterebbe di ghiaccio come quello terrestre, sarebbe necessario un raffinato sistema di depurazione per estrarre l’acqua mescolata ad altri elementi. (da Il post)

WATER ON THE MOON, Nasa #Nasa ##tempodacqua #thetimeofwater

A team of researchers at the University of California says that there could be way more ice water on the surface of the Moon than previously believed — and that could be a huge deal for future missions to the Moon. The researchers with this new effort believed it was likely that there was more ice on the moon than was shown during the LCROSS impact study—likely existing in shadowed craters similar to those that had been seen on Mercury (phys.org).

To find out water, the researchers carried out a parallel crater study, similar to the one they had conducted for Mercury. In this case, they studied 12,000 craters on the moon using data from the LRO. They report that they found “a similar morphological trend” in craters on the south side of the Moon, near the pole. They suggest this indicates that such craters likely harbor thick ice deposits along with other materials similar to those that are believed to exist on Mercury. The researchers suggest that if this is indeed the case, then there could be up to 100 million metric tons of ice in such craters, which they note is double the amount of previous estimates based on data from the LCROSS impact study. The researchers conclude by suggesting that future Moon missions include the use of probes that can be used to study the shaded craters to confirm their suspicions.

Mare dentro — Sea inside

Mari Verticali venne realizzata per Louis Vuitton, al padiglione Venezia, in occasione della 54 edizione della Biennale di Venezia. Plessi propone qui una nuova visione della sua flotta digitale che si sviluppa in maniera simbiotica all’interno della struttura a emiciclo del Padiglione Venezia, riempiendone gli spazi con un grandioso concerto d’acque in continuo movimento e divenire. Sei imbarcazioni in acciaio nero emergono dall’oscurità mentre sui video schermi delle chiglie sono evocati suoni, correnti e flutti di simbolici mari.

MARI VERTICALI, Fabrizio Plessi #mariverticali #fabrizioplessi #tempodacqua #thetimeofwater

In 2005 Fabrizio Plessi creates an updated version of Mare Verticale at the entrance to the Biennial Gardens: a cylinder that appears to emerge from the Venetian lagoon at a height of 44 meters, the symbol of the same Biennial of Art. In 54th Venice Biennale of 2011, Venice Pavillion is completely dedicated to him with video-installations Mari Verticali with big steel black boats, with a permanent and exciting water concert.

Fabrizio Plessi has been fascinated always by water, a recurring theme which has become the focus of his artwork in the form of installations, films, videotapes and performances.In 1970 his work was exhibited at the experimental Pavilion of the Biennial of Venice and again in 1972. His works werw installed in all the world. During the 1980’s Plessi begins to experiment with video, focusing on the illusions created between representation and reality of liquid elements which are amplified by the extreme technology of mechanical and electronic reproduction.  More recently his artistic endeavours have drawn him closer to the city of Venice, where water – focal point of his art – plays a dominant role. In 2003, Fabrizio Plessi creates an installation for the Peggy Guggenheim Collection: Digital Fall one of the most technologically advanced sculptures in the world, fully equipped with constant air-control, an ultra-flat Led screen and full colour display.
