Does Shimmer increase par?

[HawkeyeDJ]

This just occurred to me. Does the turbulence we create and desire at the surface to increase gas exchange also increase par?

I'm thinking as I see the little waves of light (shimmer) quickly crossing the surfaces of my corals that the light is being bent (briefly concentrated) like a magnifying glass does when it is used to start a fire. I'm not suggesting it is to that extent, but would it be enough to increase par, making some corals that desire more light thrive? Has this been covered elsewhere?

Wave action definitely affects it (minor). I'm not sure if shimmer does or not, but if it did I would also expect it to be negligible.

I don't think it would increase par.

Wouldn’t is be a wash at best as sometimes the light is focused more on certain spots and sometimes away with the ripples?

Doesn't increase par just temporarily redistributes it..
Probably the easy way to say it.
If you "froze" a wave it in place then yes it would concentrate the light thus increasing par.. in that spot. Like a magnifying glass.

Changing energy distribution, not increasing it..

Shimmer, caustic lines, wave action all the same.

Borrowed quote from Dana R.

First of all, it had to be taken at noon, which meant the day started early. I did shore dives, using my dive computer to estimate depth, while holding the PAR meter and recording PPFD with a pencil on a dive slate.

PAR in the Wild at Depth

So I have this article about PAR and BTA/bubble time anemones / entacmaea quadricolor at depth. I'm especially interested in this chart. Am I interpreting it correctly in saying: - PAR in open water at 0m is like 1800 (as we generally measure this in the reef hobby) on a presumably clear...

The caustic network (glitter/shimmer) caused readings to vary wildly, so I had to estimate an average over the course of a minute or so.
