MARS 1010 - Gases and Nutrients Objectives/Review Questions 1. What physical/chemical factors control how much gas there is in the ocean? How do these factors vary in the ocean? The most obvious source of gas is from the atmosphere. Gasses from the atmosphere and ocean are exchanged back and forth. These exchange rates are influenced by wind, waves, etc. More wind and waves means more gas forced into the ocean. Temperature, pressure, and salinity affect the solubility of gas in the ocean. Gas is more soluble at low temperatures. o Thus, cold water holds more gasses Amount of gas depends on depth and amount of life. Life brings into play things such as photosynthesis, respiration, and decomposition. The most abundant dissolved gasses in the water are o Nitrogen o Oxygen o Carbon dioxide 2. What biological factors control how much of some gases (e.g., N 2 , O 2 , CO 2 ) there are in the ocean? How do these factors vary in the ocean? Oxygen profile: there is a whole lot of oxygen at the surface because photosynthesis is occurring and it is coming from the atmosphere. This makes carbon dioxide levels low. As you travel down to the mesopelagic, there is less oxygen because microbes use
