Meanwhile, an earthquake with a magnitude of 5.2 on the Richter scale hit the Greenland Sea, in between Greenland and Svalbard, on June 9, 2017 at 20:49:52 UTC at 79.931°N, 0.605°E and at 18.4 km depth. On June 12, 2017, methane levels as high as 2740 ppb were recorded, as the image below shows. While the image doesn't specify where these high levels occurred, the magenta-colored area near Greenland looks ominous, also because such high levels do not typically result from biological releases, but instead point at concentrated plumes such as can occur when clathrates get destabilized.

Arctic methane gas emission 'significantly increased since 2014' - major new research

New expedition in Laptev Sea suggests increase in the rate of underwater permafrost degradation.
The findings come from an expedition now underway led by Professor Igor Semiletov, of Tomsk Polytechnic University, on the research vessel 'Academic M.A. Lavrentyev' which left Tiksi on 24 September on a 40 day mission.
The seeping of methane from the sea floor is greater than in previous research in the same area, notably carried out between 2011 and 2014.
'The area of spread of methane mega-emissions has significantly increased in comparison with the data obtained in the period from 2011 to 2014,' he said. 'These observations may indicate that the rate of degradation of underwater permafrost has increased.'
Detailed findings will be presented at an international conference in Tomsk on 21 to 24 November. The research enables comparison with previously obtained data on methane emissions
Arctic methane gas emission 'significantly increased since 2014' - major new research
Looks like a lot of people are taking increasing methane very seriously.
