Dear Michael and Bhaskar,
Thanks for these thoughts - they could become the basis of something useful
in the Arctic to suppress methane:
5. *Will this method address tundra methane release?* Not completely,
however this method could seed even the smallest body of standing water
within a tundra
It is not a safe assumption that anoxia in the water column is a factor in
most methane emissions from water bodies. With fossil methane release,
oxygenation is unlikely to be of much assistance. Only where methane is
produced in the water column in anoxic or hypoxic conditions would this
method

In practical terms, hypoxia is best addressed indirectly, e.g. by
controlling fertilizer runoff
This is as practical as reducing CO2 emissions.
Methanogenesis usually occurs below the photic zone and mixed layer - and
mixing of co2 could also be a limiting factor. Therefore biological

It would be simple to experiment on ponds which are producing methane, and
see if a spray of diatoms, with or without nutrients, could have a
significant effect.
BTW, I would expect that such an experiment has been done already - does
anybody know?
I have been trying for past few years to
I'm not against biological methods, you just can't easily use them for
oxygenation - as nature is pretty good this way anyhow.
There are many practical ways to reduce fertilizer use. Stopping perverse
farming subsidies is one, taxing fertilizer use is another.
Reducing nox from fertilizer may
I'm looking for things (anything!) that will work in the Arctic.

Andrew,
First, the conceptual sketch I proposed in this thread has turned into a
bucket of worms and I need to admit failure. Bhaskar may be able to further
carry the ball with his knowledge on the use of diatom nutritional
enhancement, however I can not give any further support to the
John, Andrew -
P.S. Any brainstorming ideas like this for the methane-busting workshop,
London 3-4 September, are most welcome.
Try to get Euan Nisbet, who lives there in London and deals with
methane emissions, to take part. But if you specifically want to try
to exploit methanotrophy, as in
Bhaskar,
You state reasonable points. However, there may be a need for multiple
approaches which use multiple means. Tundra based pools/lakes would have no
practical use for mechanical mixing, where as, open ocean areas with strong
currents would possible better benefit from a focused
Michael
Harvesting methane would be very useful.
Installing any hardware in lakes and oceans would interfere with the water
ecology and what would you do with these after the life ends in say 50
years.
After all global warming started since 50 or 100 years ago no one thought of
what would be
