Not certain where to post this ..this seems to be the
only google weather group with much discussion

Watched this video - Global Aerosols in atmosphere
from August 24 2006 until April 1 2007 -
http://www.space.com/18514-the-painterly-mixing-of-aerosols-in-our-atmosphere-video.html

2 minutes into video there's a very large amount
of sulfates in Indian ocean between Madagascar and
Africa. The dates of bloom ~ January 11 until January 21.
Bloom appears to begin close to Comoros Islands,
after nearly two months of sun directly above.

I did some googling and determined gas released
was probably caused by some sort bacteria requiring
warm water. (hydrogen sulfide gas released?)

Anyone know anything about these blooms and
the critters responsible for it?

Looks very impressive on satellite at least.

Earth Observatory has an article on the blooms in that part of the
world. It concerns the snow levels on the Himalayas.

Since the bloom you speak of concerns a mere week in January 2007 and
includes a substantial portion of the China Sea in the same period
around 21 to 27th I suggest you look at what happened volcanically at
the Smithsonian archives for example:

Nothing apocalyptic but a steady steam of nutrients got released in
the regions north east of both places.

I find it hard to believe it was so easy to discern that the masses
was sulphates.
OK if the sensors were from spy satellites but how would they know
what was feeding algae?

I was also wondering how the sulphates were being discerned --
weather satellites have visible, water vapor and several IR
instruments. Perhaps sulphates are detectable within some
of the IR channels.

Space.com listed it as a simulation.. however it looks like
a composite of real satellite data possibly composited with
simulated data. So the bloom may be fantasy. Hence my
questions.

I've been looking at 'full disc' weather satellite imagery
(Dundee!) for > decade. All I can say is if the space.com
animation is purely a numerical simulation it's very impressive.
It looks plausible.
