As ocean acidification begins to make its mark, scientists have also begun to further examine different bodies of water in respect to the decreasing pH levels. Byrne and colleagues at the University of South Florida studied pH level changes in the Northern Pacific Ocean between 1991 and 2006 at various latitudes. pH levels were determined by spectrophotometry of samples collected along 152°W. Atmospheric CO2 levels were also determined for this time period, however using a model. Byrne and colleagues found that pH changes were largest at 29°N and 56°N, with pH levels sub 7.3. They believe this may be attributable to these areas having low O2 levels. Comparing the increases in atmospheric CO2 with the changes in pH levels, The team concluded that the rate of pH decrease is on par with atmospheric CO2 increases. This study provides additional evidence on ocean acidification, and its affects on yet another body of water.
I like how you were clear, concise, and to the point. I also like that you found a study that clearly relates atmospheric CO2 to pH change in the ocean.
I agree. This is straightforward and informative. I found it interesting that they believe one reason could be oxygen deficiency
