Oceanography Week 5 Breaking into the beginning of Ocean Acidification, understanding the science behind it as well as the result of varying degrees of acidification. We will be specifically looking at the effect it has on plankton because they are the basis of the oceanic food chain. Current articles are showing a correlation between the concentration in acidification and the death rates of shellgrowing marine life. It seems that they are corroding away before they can properly develop. NaCl will/will not dissolve as more water is added. The solubility of NaCl is 360 g/L, which means that per liter, 360 grams of salt can be dissolved, the rest will not. Ocean salts do not necessarily come from inland rivers. The atmosphere is actually a very good source of salts. Hydrothermal vents can also contribute to the content in addition to acting as a sink (removal) of the salt material. O2 concentrations in polar surface seawater are highest because they are colder than the water in the tropics. That is why the area is heavily fished. At the surface, the amount of dissolved gas id due to gas pressure, water temperature, and molecular properties. Oxygen is increasing in deep water because of the cold polar water saturated on O2 pH decreases 1000 m down The typical pH of the ocean is 8.1 DIC Dissolved Inorganic Carbon Colder surface temperatures in the poles result in higher O2 concentrations Cl is the only conservative ion Anions have a negative charge The temperature of the gas affects the solubility
