Methane Leaking Through Cracks in Arctic Sea Ice

There are 4 comments on the Ecology Global Network story from May 9, 2012, titled Methane Leaking Through Cracks in Arctic Sea Ice. In it, Ecology Global Network reports that:

As Earth's climate warms, that methane is vulnerable to possible release into the atmosphere, where it can add to global warming .

Clathrates from thousands of feet under the Arctic Ocean isn't the source, it seems. So a biological explanation seems not to be an overwhelming source for concern.

However, the source paper's abstract in Nature Geoscience says:

.. methane is produced in the surface ocean[3] and the surface waters of the Arctic Ocean are supersaturated with respect to methane[4, 5]. However, the fate of this oceanic methane is uncertain.

.. high methane concentrations are restricted to areas over open leads and regions with fractional sea-ice cover. Based on the observed gradients in methane concentration, we estimate that sea–air fluxes amount to around 2 mg d−1 m−2, comparable to emissions seen on the Siberian shelf. We suggest that the surface waters of the Arctic Ocean represent a potentially important source of methane, which could prove sensitive to changes in sea-ice cover.

Try again:

"sea–air fluxes amount to around 2 mg d-1 m-2, comparable to emissions seen on the Siberian shelf."
