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...

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...

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...

Modern technology and global demand have collaborated to make mining precious metals from the colossal, mysterious depths of the ocean floor economically practical for the first time in history, the Associated Press reported.  In New Guinea, a progressive project is underway and new guidelines to preside over deep sea mining will be assigned by an international authority this spring. Scientists, businessmen and policymakers representing 20 countries will meet in Cape Cod on Thursday for...

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...

Deep beneath the surface of the Atlantic Ocean, geochemist Andrea Koschinsky says she has discovered the hottest water ever to be found on Earth. "It's water, but not as we know it," she said. The fluid can be seen flowing from two black smokers, named Two Boats and Sisters Peak, more than 3 kilometers below the surface of the ocean. It is in what scientists call a "supercritical" state that has never been seen before. Koschinsky said the fluid is in between a gas and a liquid, and could...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
