how to calculate ppm for co2 of in ocean

Since its creation, the Keeling Curve has served as a visual representation of Keeling’s data, which scientists have continued to collect since his death in 2005. By analyzing the CO 2 in his samples, Keeling was able to attribute this rise to the use of fossil fuels. At Mauna Loa, he discovered global atmospheric CO 2 levels were rising nearly every year.

Coral Reefs Under Rapid Climate Change and Ocean Acidification Ove Hoegh-Guldberg, et al, Science 14 December 2007: Vol. Keeling was able to establish a permanent residence at the Mauna Loa Observatory in Hawaii to continue his research. atm approaches 480 ppm and carbonate ion concentrations drop below 200 mmol kg1 in most of the global ocean. He discovered CO 2 levels are highest in the spring, when decomposing plant matter releases CO 2 into the air, and are lowest in autumn when plants stop taking in CO 2 for photosynthesis. By studying his measurements over the course of a few years, Keeling also noticed a larger seasonal pattern. He drew on his understanding of photosynthesis and plant respiration to explain this observation: plants take in CO 2 during the day to photosynthesize-or make food for themselves-but at night, they release CO 2. The air samples taken at night contained a higher concentration of CO 2 compared to samples taken during the day. Keeling began studying atmospheric carbon dioxide in 1956 by taking air samples and measuring the amount of CO 2 they contained. The Keeling Curve is named after its creator, Dr. The Keeling Curve is a graph that represents the concentration of carbon dioxide (CO 2) in Earth’s atmosphere since 1958.
