<br class="">
This is the first time I have heard of such a thing. The ocean surface
is extremely resistant to changes in CO2 concentration as it has a huge
buffering capacity with multiple latent mechanisms that kick in when
they can. The ?net loss of photosynthetic activity in shallow waters?
because on ?an increase in CO2? is unbelievable. Perhaps you can guide
me to the source.<br class=""><div class="gmail_extra"><br class=""></div></div>
