Methane hydrate dissociation off Spitsbergen not caused by climate change
Jan 8, 2018
Study identifies post-glacial processes as main reason
For years, methane emissions from the seabed have been observed in the Arctic Ocean off Spitsbergen. The assumption that the warming of seawater by climate change is responsible for the release of methane, has not been confirmed. Research from an international team shows that post-glacial uplift is the most likely cause of methane hydrate break-down. The study is now published in the international journal Nature Communications.
