The fact that little methane shows up elsewhere indicates that methane is present at high levels, at times over 2200 ppb, over the depth of the Arctic Ocean, and that these high levels result from methane that originates from hydrates under the seabed.
The image below, with methane readings over the past few days (from October 12 10:00 pm to October 14 11:23 pm), shows high levels of methane over the depth of the Arctic Ocean.
The image below shows methane readings at 586 mb, the altitude at which the highest methane reading was recorded on the afternoon of October 14 (a reading of 2248 ppb). Again, methane is present very prominently over the depth of the Arctic Ocean.
