My daughter, when she was young, would have said, “There’s Biology in there.” Indeed. Whatever was living in that mix was surely thriving … just look at all that oxygen! Where would we be without photosynthesis?

And where would I be without photographesis?
Speaking of biology: have people tested the bubbles in a situation like this and determined they contain oxygen? You spoke of “that mix,” so are other gases produced as well?

The mix I referred to was one of plants, algae, bacteria, cyanobacteria, diatoms, and who-knows-what-else. The oxygen produced by photosynthesis (and the gas in the bubbles) is pure oxygen (20.95% in ‘air’). As far as the balance of the air we breathe … respiration produces carbon dioxide (0.033% in ‘air’) and nitrogen fixation produces nitrogen (78.08% in ‘air’). I have no idea where the argon comes from (0.93% in ‘air’)!

I’m familiar with the general distribution of gases in the atmosphere, but what I meant to ask was whether processes are going on in or around the algae that add gases other than oxygen to these bubbles.

I don’t believe so.

Then that raises the question of whether a mat of bubbles like this is combustible. No one is likely to put a lighted match to one, but I couldn’t help wondering what would happen if someone did.

That’s an empirical question. I would guess that the experiment would be tough to do in such a highly aqueous environment.

I’ve wondered if we’d get a brief blaze atop a creek, a small version of the way polluted rivers (notoriously the Cuyahoga in Ohio) sometimes used to catch on fire.

This is one that became even more interesting when enlarged. The bubbles are cool, but I really like the strands that are woven through them. Or, perhaps the bubbles have (appropriately enough) bubbled up through the strands. In either case, it’s a great image, and the addition of the lightly-laying leaf is perfect.
March 19, 2016 at 7:48 AM
The strands that run through and on algae bubbles have always appealed to me too. No doubt scientists have studied the formation of bubbles of this sort, but I have no idea how they form, how long the process takes, and what conditions are required.
As for the leaf, I assume it fell from one of the nearby live oaks. It was important for the little area of contrasting color it provided.

This one is edging around my previous favorite from your algae images. Quite an interesting mix of textures and very appealing with the leaf for a textural contrast.
March 19, 2016 at 10:12 AM
It’s good to hear that this image is raising the bar. As you see from the enlargement of a little piece, there’s lots of detail here, considerably more than in your other favorite from a decade ago, thanks to advances in sensor technology.
The leaf was a bit of good luck, offering extra color and different texture.
Speaking more generally and thinking of some of your recent images: what I lack in ice I try to make up for in algae, and I don’t have to freeze my extremities off in the process.
March 19, 2016 at 10:31 AM
Lucky you. Tomorrow morning my extremities will freeze and then tomorrow night we are due for some early spring snow. Out like a lion, it seems.
March 19, 2016 at 6:08 PM
We have confidence in you as a lion tamer.

Fantastic! Love the close-up of the brew.
March 19, 2016 at 11:40 AM
You’ve made me wonder what this would like through a microscope.
March 19, 2016 at 12:21 PM
This is amazing. And of course, a great photo as well!
March 19, 2016 at 10:06 PM
Thanks, Nandini. I keep being fascinated by algae bubbles.
March 19, 2016 at 10:19 PM
The science of this picture is interesting and the close-up, extremely beautiful. I could look at those bubbles and filaments for way too long, Steve. 🙂

Sounds like there’s a smartphone app in there somewhere, Jane. I can see the newspaper headline now: “Pedestrian creates own bubbles falling into fountain while absorbed in algae bubbles phone app.”

March 20, 2016 at 8:12 AM
Maybe by rights I should expect one happy face per bubble.
March 20, 2016 at 8:35 AM
Sounds fair to me, Steve. 🙂
March 20, 2016 at 9:05 AM
Beautiful composition, Steve!
March 20, 2016 at 10:27 AM
Thanks, Lavinia. The bubbles extended broadly enough that I could maneuver the camera to keep the fallen leaf off to one side.

Must be in honor of the sparkling water and slightly effervescent [Texas] Muscat Canelli we shared last night at dinnertime….
March 21, 2016 at 11:56 AM
And yet you wouldn’t want to drink any of this brew, with its quite different effervescence.
March 21, 2016 at 9:57 PM
It does make me think…wonder…would algae have any of the health benefits of seaweed? Hmmm…
March 21, 2016 at 11:33 PM
Good question. There are many kinds of algae, and even if some of them are nutritious, I have no idea how palatable they are. The water in this pictures was becoming stagnant, so I don’t think we’d want to ingest anything that came from it.
March 22, 2016 at 12:01 AM
These photos are unique and beautiful!
It is a fascinating glimpse into a beautiful and special world you are giving us.
March 23, 2016 at 6:37 PM
You’re welcome. I’ve been doing lots of abstractions this year, especially with algae but also with lichens and rocks.

Thanks. There’s a beauty in complexity.
