Bill Nye discusses the discovery of hydrothermal vents on the ocean's floor
In many areas of high volcanic activity, water seeps into the sub-surface where it is intensely heated and then finds its way to the surface again. Examples on the land include hot springs in therapeutic spas, and special types like geysers and fumaroles. In the ocean, this circulation occurs most commonly at the mid-ocean ridge, the world's longest mountain chain. Here, far below the depth of sunlight penetration, hydrothermal vents at over 400°C with their dissolved compounds provide the basis for complex ecosystems.

One of the strangest ecosystems on earth lies deep under the ocean.
While exploring near the Galapagos Islands, the team of E/V Nautilus discovered a huge "black smoker" hydrothermal vent more than 10 meters tall billowing a cloud of dark superheated fluid and teeming with strange life. E/V Nautilus is exploring the ocean studying biology, geology, archeology, and more. Watch http://www.nautiluslive.org for live video from the ocean floor.

Since being discovered in 1977, Hydrothermal Vents have been a source of huge interest, due to their rich diversity and huge populations of new and specialised species in a comparatively baron and homogenous abyss. The mineral rich chimneys spew out a sulphurous fluid which forms an energy source for microbes, forming the base of these fascinating and unique ecosystems. Their isolation and mysterious interconnectivity reveals a fragile web of life that still has so much more left to be fully appreciated. The vents have also caught the attention of deep-sea mining contractors. 30 years on from their initial discovery, the global population has doubled and commodity prices have increased. Now, with new technological advances, deep-sea mining has become an imminent reality. Specialist resea...
During a recent expedition to the Gulf of California scientists from MBARI discovered a new field of hydrothermal vents, the deepest yet discovered in the Gulf of California. These new hydrothermal vent fields were found over thirty-eight hundred meters below the surface in the Pescadero Basin, located off the east coast of Mexico’s Baja California, about one hundred miles east of La Paz. These hydrothermal vents result from a unique combination of geology and chemistry. Using a remotely operated vehicle, researchers found towering white columns emitting geysers of clear shimmering liquid with temperatures up to 290 degrees Celsius. The superheated water flowing from these vents starts deep underground. As the hot water rises, it flows through and reacts with the surrounding bedrock, becom...
While exploring near the Galapagos, the team of E/V Nautilus encountered some beautiful creatures, including the Flamboyant Squid Worm, a species just discovered in 2007.

NOAA is an agency that enriches life through science. Our reach goes from the surface of the sun to the depths of the ocean floor as we work to keep citizens informed of the changing environment around them. From daily weather forecasts, severe storm warnings and climate monitoring to fisheries management, coastal restoration and supporting marine commerce, NOAA's products and services support economic vitality and affect more than one-third of America's gross domestic product. NOAA's dedicated scientists use cutting-edge research and high-tech instrumentation to provide citizens, planners, emergency managers and other decision makers with reliable information they need when they need it. NOAA's roots date back to 1807, when the Nation's first scientific agency, the Survey of the Coast, ...
In the darkness of special places like the Endeavour Hydrothermal Vents, ocean research is bringing to light deep secrets about life on earth and potentially elsewhere in our universe. “Black Smokers” and hydrothermal vents Create an ecologically-rich oasis in the deep sea where chemosynthetic creatures thrive and chemicals provide life-sustaining energy.
The earth cracks open. Fluid and minerals spew up from the seafloor. Water shimmers. Life abounds. We're looking at hydrothermal vents, originally discovered near the Galapagos Rift in 1977. Basically, a hydrothermal vent is a hot spring produced by underwater volcanoes or tectonic activity. Original video source: http://oceantoday.noaa.gov/lifeonavent/welcome.html Ocean Today is an interactive exhibit that plays short videos on ocean related themes. Visitors can select from 150+ videos on topics ranging from deep-‐sea exploration, marine species, and restoration projects to hurricanes, oceans and human health, and climate science and research. These videos are a free resource and are available on our website at oceantoday.noaa.gov.
We created this video in celebration of the second annual International Polychaete Day (July 1, 2016). It highlights polychaete worms with special adaptations enabling them to survive in extreme environments on the deep seafloor, such as decaying whale skeletons and hydrothermal vents. Some of these worms can tolerate water temperatures up to 176 degrees Fahrenheit! Video editing/script: Kyra Schlining Narration: Shannon Johnson Williams Music: Jaracanda.caf (Apple Inc.)
