Note to recorder:

Please, natural speed please.I am reading scientific articles related to ocean.


Concerns have been raised about how coral reefs will be affected by ocean acidification1, 2, but projections of future seawater CO2 chemistry have focused solely on changes in the pH and aragonite saturation state (Ωa) of open-ocean surface seawater conditions surrounding coral reefs1, 2, 3, 4 rather than the reef systems themselves. The seawater CO2 chemistry within heterogeneous reef systems can be significantly different from that of the open ocean depending on the residence time, community composition and the main biogeochemical processes occurring on the reef, that is, net ecosystem production (NEP = gross primary production − autotrophic and heterotrophic respiration) and net ecosystem calcification (NEC = gross calcification − gross CaCO3 dissolution), which combined act to modify seawater chemistry5, 6, 7. On the basis of observations from the Bermuda coral reef, we show that a range of projected biogeochemical responses of coral reef communities to ocean acidification by the end of this century could partially offset changes in seawater pH and Ωa by an average of 12–24% and 15–31%, respectively.

I read it slowly, similar to doing a scientific presentation (you should speak slowly and clearly with scientific presentations, at least in English).

Thanks for the note Chris. Absolutely, you are right!

This was only my second recording and I've realised that my microphone is CRAP! There's loads of background noise.

Also, I'm not sure what 'omega a' is, so I just read it like that (I'm a geologist).

No worries, Chris, I used my headset to make the sound louder. Omega is just a unit, and we call omega as well. Are you a earth science scientist? Cool! I am an oceanographer!
