Thousand of new volcanoes revealed beneath the waves

The true extent to which the ocean bed is dotted with volcanoes has been revealed by researchers who have counted 201,055 underwater cones. This is over 10 times more than have been found before.
The team estimates that in total there could be about 3 million submarine volcanoes, 39,000 of which rise more than 1000 metres over the sea bed.
"The distribution of underwater volcanoes tells us something about what is happening in the centre of the Earth," says John Hillier of the University of Cambridge in the UK. That is because they give information about the flows of hot rock in the mantle beneath. "But the problem is that we cannot see through the water to count them," he says.
Satellites can detect volcanoes that are more than 1500 m high because the mass of the submerged mountains causes gravity to pull the water in around them. This creates domes on the ocean's surface that can be several metres high and can be detected from space.
Data overload
But there is a multitude of small volcanoes that have gone undetected. The only way of identifying them is to manually find their outline on sonar measurements taken from ships.

I’m sure this is somehow related to GLOBAL WARMING.
No doubt this is caused by global warming. I wonder how many carbon offsets do we need to purchase to prevent them from erupting?
I always love these type of articles.......a general question............I’ll comment way deep in the thread
....Why are the Oceans salty ?........
Warms the water, pollutes the air and probably has sunk some ships and caused some planes to go down over water.
Bush’s fault!
It's not new volcanoes -- its newly found volcanoes. I was astonished for a moment...
Pretty interesting - I wish they'd elaborated on this phenomenon though. Wouldn't the gravity caused by the mountain mass itself pull the water down causing a dish, rather than dome, on the oceans surface?
Because of Joe Cocker?.....
good eye but there is more it tells ya
of all the threads, in all the posts, you come here,here and figger it out..........LMAO
( I’d aguessed Buffet what with the Margaritaville stuff)
It would if it didn’t also pull more ware in from the sides...
To improve the taste?
ware=water.
My personal theory is that these underwater volcanoes and other steam vents, when very active, cause El Nino. I don’t have any proof, but it makes sense to me. It would take a tremendous amount of volcanic activity just to heat the Pacific Ocean to the point that an El Nino occurs. If this is true, it would be enough to heat the Pacific enough.
This could be a source for more carbon in the atmosphere....
“Pretty interesting - I wish they’d elaborated on this phenomenon though. Wouldn’t the gravity caused by the mountain mass itself pull the water down causing a dish, rather than dome, on the oceans surface?”
Nope! Gravity isn’t just perpendiculat to the ocean surface. It would also pull every way perpendicular to the mountan mass and thus the net effect would be a bump.
The hot ocean is sucking them up like the blackhead vacuum that used to be advertised in magazines.
Gads! Volcanoes spewing all those greenhouse gases and polluting the sea. Congress has just got to pass a law to prevent this travesty.
OK so the oceans surface is randomly pimpled and pocked with "water domes" which measure in metres, an equatorial bulge of about half a metre (between Maine and Miami) due to rotation and never ending wave action of indeterminate height due to winds. So how do you define the "average sea level"? Let alone measure it with millimetre precision? Establishing that baseline number is necessary to be able to document any increase as predicted by global warming alarmists.
I know, we'll use a satellite based radar system! Except that's measuring a point value not an average. It is almost like measuring the average height of an American male. By the time you finish measuring all the required points, they have all changed in value.

Notice when the news is being reported...during Bush’s term...and it’s taken this long for someone to say the obvious “Bush’s Fault”!!!??
