Hundreds of Methane Plumes Erupting Along East Coast
Source: Livescience/Yahoo
In an unexpected discovery, hundreds of gas plumes bubbling up from the seafloor were spotted during a sweeping survey of the U.S. Atlantic Coast.
Even though ocean explorers have yet to test the gas, the bubbles are almost certainly methane, researchers report today (Aug. 24) in the journal Nature Geoscience.
"We don't know of any explanation that fits as well as methane," said lead study author Adam Skarke, a geologist at Mississippi State University in Mississippi State.

(21,317 posts)This is theorized to be because the oceans are absorbing much of the heat. Methane releases from frozen clathrate sources could be related to this heat absorption.

(14,881 posts)"Most of the methane seeps are in water less than 1,640 feet (500 meters) deep. Most of these shallow methane seeps seem to arise from microbes blurping out methane, the researchers said. The researchers did find some deeper methane vents, at which the ROV Jason glimpsed patches of methane hydrate. This is the icy mix of methane and water that appears when deep ocean pressures and cold temperatures force methane to solidify. Any type of methane gas can form hydrates."

(19,276 posts)"A shift in the salinity of the north Atlantic triggered the effect around the turn of the century, the study says, as surface water there became saltier and more dense, sinking and taking surface heat down to depths of more than 300 metres.
Using temperature data from floats across the world, Tung found the Atlantic and Southern Oceans each account for just under half the global energy storage change since 1999 at below 300m. The studys result, he says, does not support the Pacific-centric view of earlier work on whether heat is being stored. "
Gee, I wonder what happens when you give methane-generating bacteria warmer water to live in?

This effect will continue to increase even if we switched to Green Fuels 100% now, and of course that ain't close to happening. We are living our lives at the expense of future generations (this is no exaggeration or hyperbole) We also need to make plans of survival, as this is gonna happen faster and faster.

(16,296 posts)As more methane is produced (by whatever cause) ,it reacts with ozone - converting it to oxygen which allows more heating of the planet which in turn warms the waters allowing more methane to be produced. Not a cycle of life, but of death.
" The density, i.e; the mass per unit volume of methane is less than that of air (which is a mixture of many gases) Methane react with ozone converting it into oxygen and thus the ultraviolet absorbing power is lost. More percentage of UV rays will reach the earth. Normally about 50% of the UV rays reaching the upper atmosphere are absorbed or reflected back."

(9,154 posts)and in the shade it was a fairly normal 86 °F, when in the direct sunshine, it felt like an oven, like the ozone hole was between me and the sun, definitely a radiant heat. I wonder if there's a way to measure radiant heat directly from the sun?

(74 posts)An excellent summation is below of material from http://arctic-news.blogspot.com/, that clearly states what the timeline is for our extinction, due primarily to abrupt release of geologic AND biologic methane. The video discusses earthquakes along the faults in the Arctic, in some detail, which just may remind you of Bardabunga volcano (thank goodness! it's eruption is not disturbing our flight plans... it's erupting under a 2000 m glacier, whew!)
Anyway, all this is surely to be abundantly clear in time for 2016.

(188 posts)I'm thinking if it's the same phenomena there should be blow-holes inland along the coast of the US too. If they can't find any it's likely just a matter of time
before they blow. The Siberian peninsula is deserted but for a few farmers & their herds. The east coast of the US is so heavily populated it's a given that
people are going to get hurt.
