PPT-The Effects of Ocean Acidification on the Physiology of Dominant Antarctic Algal Species

Amelia Snow Dr Oscar Schofield and Dr Grace Saba The CO 2 Problem Since 1800s 40 increase Preindustrial 280 ppm Current 385ppm 05 increase per year Ocean absorbs 13 CO 2 in atmosphere. Acidification Tolerance of Aquatic Organisms . Analysis. Conclusion & Applications. Data & Observations. Introduction. Different species respond to low levels of pH differently: some of the test subjects were . For tens of millions of years, Earth's oceans have maintained a relatively stable acidity level. It's within this steady environment that the rich and varied web of life in today's seas has arisen and flourished. But research shows that this ancient balance is being undone by a recent and rapid drop in surface pH that could have devastating global consequences.. Developed in 2014 by Matthew Crane, Science Instructor, Northern Marianas College, Saipan. CO. 2. What is Mass Balance. The . law of . conservation of mass. . implies that mass can neither be created . Key understanding. Due to the use of unsustainable energy, ocean acidification is a rising problem for marine ecosystems. The high levels of pH (acidity) in the water alters the natural chemical bonding process in regards to the building of shells and exoskeletons of marine wildlife. The rising level of .
