how to calculate ppm for co2 of in ocean

analyze and compare times series data sets of atmospheric CO 2, sea surface CO 2 and ocean pH.conduct a short experiment to investigate the relationship between increased CO 2, acidity and pH.To better understand what ocean acidification is and why it happens, you will: Scientists are concerned that ocean acidification a gradual acidification of seawater could have negative consequences for marine organisms, marine food webs, and entire ecosystems. They project that this trend will continue in this century as indicated in the visualization pictured on the right. Scientists have also observed that the oceans have become more acidic since the beginning of the Industrial Revolution. Some of this excess CO 2 ends up in deep ocean currents that eventually upwell along coastal areas bringing all that excess CO 2with them and to oyster farms. That's 2.5 billion gigatons of excess carbon that moved from the atmosphere into the ocean each year during that one decade. Source: US National Center for Atmospheric Research Community Climate System Model 3.1 (CC SM3)-modeled decadal pH at the sea surface centered around the years 1875, 1995, 20.Recent estimates by scientists ( Le Quere et al., 2012) have calculated that approximately 26% of all CO 2 emitted from human-related activity was absorbed by the oceans during the decade 2002 - 2012. Blue indicates less acidity yellow/orange indicates greater acidity. Changes in ocean acidity as measured by pH.
