[Coral-List] Bubbles from Millepora skeleton

[Risk, Michael]

   Who, me? I've been cantankerous for lots longer then that.

   Dave: I didn't realise it was paywalled-I will send a copy to your
   email. Any anyone else who wants one.

   Although the O2 may supply the critter, I can't imagine most shallow
   orgs being O2 starved. More to the point: there is no gas in the corals
   in the morning. It builds up all day, under influence of light. So all
   this oxygen leaks out overnight, from the activities of boring algae.
   Which are present in every carbonate grain, every coral skeleton.

   Remember all those papers from decades ago, on reef productivity? Based
   on gas production? And all the O2 was deemed produced by corals as they
   grew? Well, a significant amount of the O2 was produced by destructive
   orgs. I have never trusted those papers.

   May the Millepora goddesses forgive me for all the branches I pinged
   off. But it's great fun.

   Mike

   Interesting, thank you Mike.
   (No thank you to Science for locking up copyright and paywalling the
   article).
   Tom, in this case it was a clean white break, but I have seen that
   green
   layer before.  And it was in the day: late afternoon.
   I wonder if there is any potential for this skeletal oxygen to supply
   the
   organism when it's running low in the early hours?
   1892 huh? No wonder he is cantankerous.
