• La rose des vents.
• Je suis née à l'envers Tout au bout de la mer Dans un lotus ouvert Aux bras de shiva Loin de chez toi J'ai grandi, j'ai rêvé Aux pays des orchidées Aux masques rouges et dorés Qui marquent mon âme Aussi fort que tes charmes Et j'ai suivi le chant de mes veines Aussi loin que m'entraînent tes pas J'ai tourné la rose des vents vers tes plaintes Si fort que j'en saigne parfois Loin de chez moi J'ai appris ton espace Les saisons froides qui passent Nos coeurs à la surface Au nord de mes lois Plus au nord que tu crois Je veux t'emmener là Marcher la tête en bas Saluer Ganesha Sur les cendres chaudes De mes rêves émeraudes Et j'ai suivi le chant de mes veines Aussi loin que m'emmène ta voix J'ai tourné la rose des vents vers tes plaines Si fort que j'en saigne parfois J'ai lâché la rose des vents pour tes signes Et je sens tes épines sur moi sur moi Et si je suis fidèle Aux flèches des hirondelles Aux elfes qui m'ensorcellent Au nom de ta voix Où que tu sois J'appellerai toujours La croix du sud au secours Quand je serai à mon tour La rose des vents, qui guide les amants Si j'ai suivi le chant de mes veines Aussi loin que m'emmène ta voix Je serai la rose des vents vers tes plaines Si fort que j'en saigne parfois Je serai la rose des vents qui parfume Tes jours et tes lunes Chez moi, Chez moi. ...

• These vents are found in some of the deepest places in the ocean, far beyond the reach of normal submarines or divers.
• Hydrothermal vents are formed where two oceanic plates pull apart and erupting lava replaces the sea floor.
• Cold seeps are areas similar to hydrothermal vents. Though the cold seep waters are about the same temperature as the surrounding waters, they are called cold seeps in contrast to the extremely hot fluids from hydrothermal vents. The cold seeps support organisms similar to the hydrothermal vents though the exact make-up of the biological community surrounding them depends on the chemicals, such as hydrogen sulfide, methane, iron, manganese and silica, found in the cold-seep fluid.

• Oceanographers struggle to explain a strange glow from seafloor vents.
• Discovered 8 years ago, the light issues from ridge-top vents that spew out volcanically heated brines laden with metals and caustic compounds. ...
• These shrimps swarm around hydrothermal vents on the volcanically active mid-Atlantic ridge, which forms part of an underwater mountain range encircling the planet like the seam on a baseball. ...
• Suspecting that the shrimp uses these eyes to see light coming from the hydrothermal vents, Van Dover, Milton Smith, and John R. ... Although far from ideal, their camera recorded an extremely faint glow coming from the vents. ...
• Piggybacking their experiment on unrelated Alvin dives, Van Dover managed to collect some data during free moments at the tail end of expeditions to hydrothermal vents in the Atlantic and Pacific Oceans.
• The scientists found more light coming off the vents than they could attribute to thermal radiation alone. ...
• Van Dover's team has now won funding that enables them to explore the vents with more sophisticated techniques. ... Such measurements, they hope, will help them to discern the mechanism creating the light at the vents.
• As a biologist, she wonders what significance the light holds for life at the vents. ...
• exoculata, she reasoned that the shrimps could use the light from vents to help orient themselves at a safe distance from the hot plumes. The animals need to get close enough to the vents to feed on chemosynthetic bacteria, which derive nourishment from the energy-rich sulfur compounds in the water, but they run the risk of getting cooked in the hydrothermal fluids if they get too near.
• exoculata and some other shrimps from the vents have enlarged retinas. ...
• Blankenship of Arizona State University in Tempe, the light measured at the hydrothermal vents may be strong enough for this purpose. "The intensity of the light from the hydrothermal vents was within an order of magnitude of that known to support photosynthesis elsewhere," he says.
• Van Dover's group estimates that the photon flux from the vents may reach a similar strength, but only in the infrared wavelength of 950 to 1,050 nanometers. ...

• In the 20 years since that discovery, scientists have found hydrothermal vents along other sections of the world's ocean ridges. Marine geologists think that these vents dissipate heat from beneath the earth's crust as tectonic plates shift and spread. ...

• Science had discovered deep sea hydrothermal vents. These vents occur in geologically active regions of the ocean floor. ... The dark color of the water spewing forth from these vents has earned them the name, "black smokers". The temperature of the water coming out of these vents exceeds 360º. The real surprise was the discovery that a myriad of life forms actually live and thrive around these vents, totally cut off from the world of sunlight.
• Here at the vents, though, something entirely different was taking place. These organisms were getting their food directly from the vents themselves. ... These waters are so fertile that shrimps have been known to literally number in the millions near these vents.

• Deep Sea Hydrothermal Vents.
• Hydrothermal vents are geysers on the ocean floor. ...
• Deep-sea hydrothermal vents form along mid-ocean ridges, the volcanic undersea mountain ranges where new seafloor is created. Before seafloor vents were actually observed, their existence was predicted because new oceanic crust cools more quickly than otherwise expected. ...

• Although hydrothermal vents are what we would consider a harsh environment, they are teeming (abundent) with life. As long as the vents remain active, which is usually one to two years, animals thrive there. In fact, more than 300 species live around the vents and are unique to this type of environment. ...
• Some organisms, such as the tubeworms, that live around the vents do not have a mouth or even a digestive tract as we do. ...
