A biofilm covers a small water filled hollow on a recently pine cleared lowland raised bog. Wind and bubbles emphasise this. Perhaps a sulphate reducing bacteria?
No identification made yet.
No interactions present.
Whatever it is, it's an excellent observation. Could natural turpentine residues be partly responsible, I wonder?
What a strange looking object, it looks like something from Dr.Who!
I'd not thought about turpentine. Would that have to come from burnt pine?

I think it could come directly from tree resin which I believe used to be tapped a bit like latex to obtain it, maybe also from the wood, though I think it doesn't extract so easily but maybe decay or chemical processes would release it - not sure.
It's a natural anti-freeze and wound sealant in some conifers. dshubble is right that it isn't readily extracted, but I'm thinking the felling would have released some. There would also be chainsaw lubricating oil (usually a polymer - nowadays often rapeseed based)around. There would also be the usual soup of decaying organics you find in a bog.
There's also the pH effect - bogs are usually quite acidic - this can cause natural emulsions to "split".
Whatever aided the process, it's almost certainly bacterial/fungal in origin, I'd say.
I agree with RogerR here i.e. that it's something bacterial and/or fungal/algal with biofilms often caused by multiple species (though sometimes just one). In my opinion, Wikipedia has a pretty good page on this, at least as an introduction: http://en.wikipedia.org/wiki/Biofilm
