"This study is important for identifying the complexity of the ocean acidification problem around the globe," said Scripps marine biologist Jennifer Smith. "Our data show such huge variability in seawater pH both within and across marine ecosystems making global predictions of the impacts of ocean acidification a big challenge. Some ecosystems such as coral reefs experience a daily range in pH that exceeds the predicted decrease in pH over the next century. While these data suggest that marine organisms may be more adapted to fluctuations in pH than previously thought much more research is needed to determine how individual species will respond over time. Importantly, these new sensors allow us continuously and autonomously monitor pH from remote parts of the world and thus provide us with important baselines from which we can monitor future changes caused by ocean acidification." scrippsnews.ucsd.edu OR ocean PH , The only question you need to focus on is why phytoplankton grow in an Iron "fortified" oceanic environment that you claim is so acidified that it depleted phytoplankton populations by 40% since 1950. when all someone has to do is fertilize a HNLC zone with Iron and create HUGE blooms of bontanical life that you claim cannot possibly flourish in those acidified waters How can botanical life suddenly flourish in the same environment that you assert has been killing them off for 60 years, merely by adding a small amount of Iron?? But the INESCAPABLE SCIENTIFIC FACT is that when Iron is added to HNLC zones, phytoplankton flourish and CO2 levels are locally reduced as those algae uptake and use it for photosynthesis. And they will do this all the way up to 1000ppm, at the very least if all other elements necessary for photosynthesis are present. HOW can you possibly have a problem with that?? Really now?
