If this vent field was on land, it would be a national park Jeff Karson, Duke University The "spires" were formed from deposits laid down by mineral-rich hot waters gushing up through rocks on the ocean floor.

Similar phenomena occur under the oceans within midocean ridge volcanoes and are called deep-sea hydrothermal (hot water) vents. They are known as black smokers , like the ones seen above. These black smokers are chimneylike structures made up of sulfur-bearing minerals or sulfides that come from beneath Earth's crust. They form when hot (roughly 350?C), mineral-rich water flows out onto the ocean floor through th Read More Go to Site

Stretching from Marin to Cambria, the MBNMS encompasses a shoreline length of 276 miles and 5,322 square miles of ocean. Supporting one of the world's most diverse marine ecosystems, it is home to numerous mammals, seabirds, fishes, invertebrates and plants in a remarkably productive coastal environment. The MBNMS was established for the purpose of resource protection, research, education, and public use of this national treasure. The MBNMS is part of a system of 13 National Marine Sanctuaries administered by the National Oceanic and Atmospheric Administration Read More Go to Site

		NOVA Online \| Into the Abyss \| Living at Extremes ^Votes:0 --> Menagerie at a hydrothermal vent. Living at Extremes by Peter Tyson If there is a harsher place to live than a hydrothermal vent, it hasn't been found yet. Pitch darkness, poison gas, heavy metals, extreme acidity, enormous pressure, water at turns frigid and searing—this seafloor environment seems more like something from deep space than from our own deep sea. Yet amazing communities of life exist at hydrothermal vents and the so-called "black smoker" chimneys that, given the right conditions, rise above them like erupting stalagmites. Blind shrimp, giant white crabs, and a variety of tubeworms are just some of the more than 300 species of vent life that biologists have identified since scientists first blundered upon this otherworldly community two decades ago.

		Ocean Planet: Popular Science - Creatures of the Thermal Vents ^Votes:0 Creatures of the Thermal Vents by Dawn Stover The three-person submersible Alvin sank through the cold, dark waters of the Pacific Ocean for more than an hour, finally touching down on the sea floor more than 8,000 feet below the surface. It was December 1993, and the scientists inside the sub had come to this stretch of the East Pacific Rise, an underwater mountain range about 500 miles southwest of Acapulco, Mexico, to inspect a recently formed hydrothermal vent - a fissure in the ocean bottom that leaks scalding, acidic water. Peering out through the sub's tiny windows, the visitors were astonished to see thickets of giant tube worms , some four feet tall. The tail ends of the worms were firmly planted on the ocean floor, while red plumes on the other ends swayed like a field of poppies Read More Go to Site

		Oceanlink \| Oceanmatters: Undersea Mining ^Votes:0 The Discovery of Marine Hydrothermal Vents Up until about 125 years ago the deep ocean floor was a mystery to the people of Earth. Scientists knew almost nothing except that there were many different species and a lot of water. The first major ocean exploration was from the Challenger Expedition from 1872-1876. The Challenger expedition covered seventy thousand nautical miles of ocean and the researchers took depth soundings every one hundred miles. Scientists regarded these depth recordings as accurate (they weren't) but it was not for many years until there was a better depth recording method. Be ginnings of Ocean Exploration The Titanic disaster of 1912 prompted the development of a new system for distance and depth recording. This new development was called the Echo Sounder.

		The World of the deep-sea organisms ^Votes:0 In the areas of structure and biota analysis of communities and examination of the dispersal of chemosynthetic communities, we continued our survey on chemosynthetic communities in Sagami Bay, the Okinawa trough, and the Ogasawara sea area. We also conducted a survey on the hydrothermal vent community found at the Daini Kasuga seamount in the north Mariana trough, an important location for studies involving the biogeography of the western Pacific. At the Daini Kasuga seamount, we discovered a hydrothermal vent community at the peak of the seamount, at a depth of approximately 400 meters. The biota resembled that found in the Kaikei seamount of the Ogasawara region. We also performed a Deep Tow survey of the cold-seep communities off shore of Kushiro in Hokkaido, and discovered a chemosynth Read More Go to Site
