The results of our recent study suggest that the Atlantic water never ceased to flow into the Nordic Seas during the glacial period,» says Mohamed Ezat, PhD at Centre for Arctic Gas Hydrate, Environment and Climate (CAGE) at UiT, The Arctic University of Norway.

Umbertoluca Ranieri, PhD student at ILL and EPFL, and lead author of this study says: «These results are important in improving our understanding of many fundamental non-equilibrium phenomena involving methane clathrate hydrates; for example, the replacement kinetics during gas exchange in case of conversion between the clathrate structures I and II.

There is also a third process, whereby during gas hydrate formation, gas hydrate can separate free gas from surrounding water.

It was developed by scientists at CAGE — Centre for Arctic Gas Hydrate Environment and Climate, and shows that seafloor off Western Svalbard was covered by a large ice sheet during the last glaciation.

Warming destabilises permafrost and marine sediments of methane gas hydrates in some regions according to some model simulations (Denman et al., 2007 Section 7.4.1.2), as has been proposed as an explanation for the rapid warming that occurred during the Palaeocene / Eocene thermal maximum (Dickens, 2001; Archer and Buffett, 2005).

The research proposed by Oklahoma State will help to further develop an understanding of the structural and geologic controls on hydrate occurrence and distribution in Walker Ridge 313 and Green Canyon 955 using new techniques to interpret gas hydrate occurrences in existing seismic data, along with well data collected during prior Energy Department research efforts at those sites.

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.

Hypotheses include (i) orbital modulation of methane hydrate disassociation and (ii) production of C - based gases during magma - sediment interactions in the formation of the North Atlantic Igneous Province (NAIP).
