Sentences with phrase «destabilize gas hydrates»

When hydrates are present below permafrost, on land and beneath shallow marine shelves, they are also thermally buffered by the latent heat energy needed to melt the permafrost and it could take thousands of years to destabilize the gas hydrates (Taylor et al 2005).

They occurred over a very short time interval immediately following onset of Cretaceous global warming, suggesting that the warming destabilized gas hydrates and released a large burb of methane.

Not exact matches

The destabilized hydrates would turn into methane gas bubbles and warm the atmosphere, Wadham and colleagues reported in a study published in Nature in 2012.

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.

Scientists from the Center for Arctic Gas Hydrate (CAGE), Environment and Climate at the Arctic University of Norway, published a study in June 2017, describing over a hundred ocean sediment craters, some 3,000 meters wide and up to 300 meters deep, formed due to explosive eruptions, attributed to destabilizing methane hydrates, following ice - sheet retreat during the last glacial period, around 12,000 years ago, a few centuries after the Bølling - Allerød warming.
