Scientists excavating the ocean floor have found huge chunks of frozen methane along Hydrate Ridge, about 60 miles off the coast of Oregon.
«As this Atlantic water, the last remnants of the Gulf Stream, propagates eastward along the upper slope of the East Siberian margin, our SWERUS - C3 program is hypothesizing that this heating may lead to destabilization of upper portion of the slope methane hydrates.
It can also melt vast quantities of methane hydrates frozen into tundra, and also at depths along the oceanic continental shelves.
As it happens, the extra heat travels into shallow seas along the continental shelf and, over time, the warming also spreads to the deep seabed, destabilizing methane hydrates and free gas trapped over millennia in the permafrost cap.
Methane hydrates are 3D ice - lattice structures with natural gas locked inside, and are found both onshore and offshore — including under the Arctic permafrost and in ocean sediments along nearly every continental shelf in the world.
The consortium will coordinate scientific input and develop plans for future marine hydrate expeditions to conduct research drilling, recovering samples of the formation, logging and analytical activities to assess the geologic occurrence, regional context, and characteristics of methane hydrate deposits along the continental margins of the United States, likely focusing on the Gulf of Mexico and the Atlantic margin.
[9] However, it is also thought that fresh water used in the pressurization of oil and gas wells in permafrost and along the continental shelves worldwide combines with natural methane to form clathrate at depth and pressure, since methane hydrates are more stable in fresh water than in salt water.
Methane hydrates are believed to form by migration of gas from deep along geological faults, followed by precipitation or crystallization, on contact of the rising gas stream with cold sea water.
