An FEI Quanta SEM electron microscope revealed a hydrothermal worm that seems monstrous when zoomed in 525 times. These worms, among the smallest living things in the world, are deep sea creatures and almost as small as bacterium. They are largely found near hydrothermal vents in the ocean. Hydrothermal vents are found near volcanically active places.  Philippe Crassous shot the image of the worm using FEI's microscope. Scientists discovered the first multicellular life in the deep...

Pyrite nanoparticles from hydrothermal vents provide a rich source of iron for deep sea life, according to new research published in the current issue of the journal Nature Geoscience. Bacteria and tiny plants living in the ocean need iron for energy and growth, but are without the ability to use natural sources such as leafy greens or red meat.  But scientists have found evidence that points to an iron source on the seafloor: tiny particles of pyrite, or fool's gold, from hydrothermal...

Scientists aboard the Royal Research Ship James Cook have discovered a new set of deep-sea volcanic vents in the chilly waters of the Southern Ocean.  The discovery is the fourth made by the research team in three years, which suggests that deep-sea vents may be more common in our oceans than previously thought. Using an underwater camera system, the researchers saw slender mineral spires three meters tall, with shimmering hot water gushing from their peaks, and gossamer-like white mats...

Hydrothermal vents may contribute more to the thermal budget of the oceans than previously assumed Scientists from the MARUM Center for Marine Environmental Sciences and the Max Planck Institute for Marine Microbiology in Bremen on board the German research vessel Meteor have discovered a new hydrothermal vent 500 kilometers south-west of the Azores. The vent with chimneys as high as one meter and fluids with temperatures up to 300 degrees Celsius was found at one thousand meters water depth...

Method included first use of Nereus hybrid vehicle in 'autonomous' mode The first expedition to search for deep-sea hydrothermal vents along the Mid-Cayman Rise has turned up three distinct types of hydrothermal venting, reports an interdisciplinary team led by Woods Hole Oceanographic Institution (WHOI) in this week's Proceedings of the National Academy of Sciences. The work was conducted as part of a NASA-funded effort to search extreme environments for geologic, biologic, and chemical...

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...

Working in a rare, "natural seafloor laboratory" of hydrothermal vents that had just been rocked by a volcanic eruption, scientists from the Woods Hole Oceanographic Institution (WHOI) and other institutions have discovered what they believe is an undersea superhighway carrying tiny life forms unprecedented distances to inhabit the post-eruption site. One such "pioneer species," Ctenopelta porifera, appears to have traveled over 300 kilometers to settle at the site on the underwater mountain...

A British scientific expedition has discovered the world's deepest undersea volcanic vents, known as 'black smokers', 3.1 miles (5000 meters) deep in the Cayman Trough in the Caribbean. Using a deep-diving vehicle remotely controlled from the Royal Research Ship James Cook, the scientists found slender spires made of copper and iron ores on the seafloor, erupting water hot enough to melt lead, nearly half a mile deeper than anyone has seen before. Deep-sea vents are undersea springs where...

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...

On the marine microbial stage, there appears to be a vast, varied group of understudies only too ready to step in when "star" microbes falter. At least that's what happens at the Lost City hydrothermal vent field, according to work led by the University of Washington and published this week in the Proceedings of the National Academy of Sciences. The Lost City hydrothermal vent field in the mid-Atlantic Ocean is the only one of its kind found thus far. It offers scientists access to...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
