“More evidence that undersea volcanoes and deep sea vents are heating the oceans,” says reader Steve Foster. “Bet they are contributing to increased CO2 levels too. Do you think Man will be blamed for this too?”
The world’s deepest known volcanic vents – called black smokers – are also the hottest, a UK-led expedition has indicated.
“The vents’ features suggest the water is warmer than 450C – hot enough to melt lead,” writes science reporter Matt McGrath.
The seafloor vents, located 3 miles (5km) below the surface of the Caribbean in the Cayman Trough, are shooting jets of mineral-rich water more than half a mile (more than a kilometer) into the ocean above.
Dr Jon Copley, from the University of Southampton and one of the leaders of the expedition, estimates the vent field at about 260 ft (80m) across and 165 ft (50m) high. “On top of the mound are naturally formed chimneys, estimated to be about six metres tall with hot fluid gushing out,” says Copley.
Of perhaps even more scientific interest is another vent field that the team discovered on the side of Mount Dent, an undersea mountain.
“The black smokers on Mount Dent were some distance from a volcanic zone and Dr Copley believes this could be a clue that vents occur in far greater numbers than previously thought,” says McGrath. (Italics added.)
“This view is shared by Dr Nicole Dubilier from the Max Planck Institute of Marine Microbiology, who has also explored deep sea vents.”
“I am convinced that deep sea vents are very common and this is only the beginning of a hopefully long line of future discoveries,” said Dr Dubilier. (Italics added.)
Details of the research have been published in the journal Nature Communications.
As I say in “Not by Fire but by Ice, “It’s not global warming, it’s ocean warming, caused by underwater volcanoes.” (Chapter 10, “Fish Stew.”)
