High
Methane Levels over Arctic Ocean continue in 2014

January, 2014
The
high methane levels over the Arctic Ocean, the
biggest story of 2013,
continue in 2014, as illustrated by the image below.
As
above image shows, high methane readings (as high as 2301 ppb on
January 6, 2014) continue in 2014. High methane concentrations
continue to enter the atmosphere where the sea ice is thin and where
the sea ice is carried by currents outside of the Arctic Ocean.
The
inset shows ice thickness on January 6, 2014. The inset highlights
the huge amounts of sea ice that are carried by the sea current from
the north of Greenland into the Atlantic Ocean.
What
is the impact of these high methane releases over the Arctic Ocean on
global methane levels? The image below shows the most recent global
methane levels available from NOAA.
Clearly,
methane levels are rising and high releases over the Arctic Ocean
will be contributing to the rise. The image below shows more recent
data, from in situ measurements at the station at Barrow, Alaska.
The
image below shows high methane releases over the Arctic Ocean, as
recorded on (part of) January 7, 2014, when levels were as high as
2381 ppb.
The image below shows methane levels on (part of) January 8, 2014, when levels as high as 2341 ppb were recorded. The inset confirms indications that these high levels originate from the Arctic Ocean
Is there any explanation of the methane slow down between approx. 1999-2008?
