Oliver Milman authored an article titled “Entire marine food chain at risk from rising CO2 levels in water” (2014) and he states, “Escalating carbon dioxide emissions will cause fish to lose their fear of predators, potentially damaging the entire marine food chain, joint Australian and US research has found.” (Milman, 2014, p. 1). As carbon is expelled into the atmosphere from the burning of fossil fuels, the oceans absorb the excess CO2.
“The ocean takes up carbon dioxide through photosynthesis by plant-like organisms (phytoplankton), as well as by simple chemistry: carbon dioxide dissolves in water. It reacts with seawater, creating carbonic acid. Carbonic acid releases hydrogen ions, which combine with carbonate in seawater to form bicarbonate, a form of carbon that doesn’t escape the ocean easily.”(Riebeek, 2008, p. 1).
Oceanographers study the carbon cycle at the National Oceanic and Atmospheric Administration’s Pacific Marine Environmental Laboratory. A device called CTD Rosette is an electronic instrument used to measure salinity, temperature, and depth. Each of the white bottles collects seawater at different depths for detailed analysis.
Oceanography is one of the sciences that in addition to geology, meteorology, and astronomy makeup Earth science. “Oceanography is actually not a separate and distinct science. Rather, it involves the application of all sciences … Oceanography integrates chemistry, physics, geology, and biology.…
