There is a huge seasonal variability in methane seeps in the Arctic Ocean, according to a new paper in Nature Geoscience. \u201cDuring cold periods the emissions from these seeps are almost halved, as if they are hibernating\u201d, says Benedicte Ferr\u00e9, the first author of the paper.<\/h4>\n

The atmospheric concentration of methane, a potent greenhouse gas, has almost tripled since the beginning of industrialisation. Methane emissions from natural sources are poorly understood. This is especially the case for emissions from the Arctic Ocean.<\/p>\n

The Arctic Ocean is a harsh working environment. That is why many of the scientific expeditions are conducted in the summer and early autumn months, when the weather and the waters are more predictable. Most extrapolations regarding the amount of methane discharge from the ocean floor, are thus based on observations made in the warmer months.<\/p>\n
