John,
As a layperson following the forum, my personal beliefs concerning your
questions are:
1) I now believe that Bright Water can be used in a localized, targeted and
prescribed manner. This would take funding for an accelerated and highly
focused campaign in both vessel design/construction and advanced
microbubble production/surfactant research. The latter requires many
considerations and trials.
2) Known atmospheric CCS methods would be difficult to use for methane.
However, here is a link to a group you may be interested in

Highly educational, John!
Air capture is "spendy" and "tough". Basically. keeping it out of the air
is more cost effective than taking it out of the air. And, I am sure you
know that, John.
3) Exploration/Drilling for methane hydrates has become an active interest
to the DoE and you can get an overview of the work in that area here.

As far as mining atmospheric methane, see #2
As far as your statement that "The methane problem in the Arctic has come
to a head".... whose head are you referring to?
As far as your statement that" Significant quantities of methane are
already appearing in the Arctic atmosphere", How Would You Know?
Thanks for the challenging questions, John.

Hi all,
The methane problem in the Arctic has come to a head. There is sufficient
carbon trapped in permafrost to cause a multiplication of global warming
by many times (at least 40 times according to my first tentative
calculation). It is critical how fast this positive feedback gets going.
Significant quantities of methane are already appearing in the Arctic
atmosphere.
Albert Kallio points out the methane lingers, hence the local greenhouse
gas effect can be significant. Thus the build up of positive feedback on
Arctic warming can grow, even before the global warming feedback gets
going. If we don't solve this problem, we may never have a chance to
solve the other crises which beset us.
I have long advocated SRM to cool the Arctic but this could be too late
to stop the methane release into the atmosphere. We are now left with
the "mission impossible" to stop the methane. We need urgent
brainstorming on this.
For example, could the Bright Water idea be applied to the East Siberian
Sea?
Could CCS ideas be applied to methane, as or after its release into the
atmosphere?
Could the methane be "mined" in some way?
Cheers,
John (on holiday for another week)
