An expedition partially funded by NASA, part of a program to search extreme environments for geological, biological and chemical clues to the origins and evolution of life, has discovered the deepest known hydrothermal vent in the world, nearly 5,000 meters (16,400 feet) below the surface of the western Caribbean Sea. The research will help extend our understanding of the limits to which life can exist on Earth and help prepare for future efforts to search for life on other planets. An...

Discovery, a First, Could Spur Exploration of Distant Mid-Ocean Ridge Scientists at Columbia's Lamont-Doherty Earth Observatory have found evidence of hydrothermal vents on the seafloor near Antarctica, formerly a blank spot on the map for researchers wanting to learn more about seafloor formation and the bizarre life forms drawn to these extreme environments. Hydrothermal vents spew volcanically heated seawater from the planet's underwater mountain ranges"”the vast mid-ocean ridge...

The cycling of iron throughout the oceans has been an area of intense research for the last two decades. Oceanographers have spent a lot of time studying what has been affectionately labeled the Geritol effect ever since discovering that the lack of iron is a reason why phytoplankton grow lackadaisically in some of the most nutrient-rich surface waters. Just like humans, sometimes the ocean needs a dose of iron to function more effectively. It is well known that the hydrothermal vents lining...

Hydrocarbons "“ molecules critical to life "“ are being generated by the simple interaction of seawater with the rocks under the Lost City hydrothermal vent field in the mid-Atlantic Ocean. Being able to produce building blocks of life makes Lost City-like vents even stronger contenders as places where life might have originated on Earth, according to Giora Proskurowski and Deborah Kelley, two authors of a paper in the Feb. 1 Science. Researchers have ruled out carbon from the...

SAN FRANCISCO -- Scientists exploring the world's sea floor have discovered new super-hot, mineral-rich geysers belching from the southern Atlantic, Arctic and Indian oceans. The findings are significant because they show that such hydrothermal vents are a global phenomena, which may help shed light on Earth's geological development and the origins of simple life. Thermal vents teeming with exotic creatures were once thought to exist only in the Pacific "Ring of Fire" because of its high...
