Deepest Most Explosive Underwater Eruption Ever Seen

Appears to have erupted near continuously since it was first observed in 2008. (Gee. I wonder what is heating our seas?)

 


Underwater eruption

West Mata volcano lies near the islands of Fiji in the southwestern Pacific in the Lau Basin.

“Here, the rate of subduction — the process in which one massive tectonic plate dives under another, typically forming chains of volcanoes — is the highest on Earth, and the region hosts ample signs of recent submarine volcanism.”

“It was absolutely stunning and exciting, something we’d never seen on the seafloor before,” researcher Joseph Resing, an oceanographer at the University of Washington in Seattle, told OurAmazingPlanet. This submarine eruption is the deepest seen yet, about 2,200 feet (700 m) deeper than NW Rota-1. This was deeper than scientists had expected to see explosive eruptions.”

“West Mata appears to have erupted near continuously since it was first observed in 2008.”

Gee. I wonder what is heating our seas?

  1. Actually, I thought I read somewhere where the total heat content in the oceans was fairly constant, so I would have to wonder where is all that heat going since the world seems to be cooling?

  2. Normally assuming oceans have a constant rate of temperatures at the surface, (first 100 or so feet in depth) the reason why the world is cooling is due to atmospheric cooling, especially at greater altitudes, in recent decades. This results in increased precipitation (and greater number of storm systems at the surface) due to the larger temperature gradient between the two. (warmer ocean – cooler atmosphere) So this would effectively cancel out any additional heat gained from the oceans being advected to land surfaces as precip tends to cool the ocean surface below, in addition to colder overall temps (in part because of stronger 500mb troughs due to atmospheric cooling) interacting with these surface features. So even an overall increase in SST’s (from oceans) would be cancelled out pretty quickly due to increased precip (rain,snow) over the ocean surface, plus the combined effect of colder air masses moving across the oceans and land areas (where snowfall can occur) at ground level. (in part due to stronger troughs at 18,000 feet) Pressure systems do mix the air (even at great heights) as they traverse across the globe. Even according to Dr Roy Spencer, the weather (precip,storms, air mass intensity, source regions and movement) controls the Greenhouse effect. Not the other way around.
