• DISSOLVED GASES - Page 12

Three gases found in the air-oxygen, carbon dioxide and nitrogen-are very important to lake ecosystems. Three main factors determine the amount of gases present in a lake:

• wind mixing that brings water into contact with the atmosphere
• the biological activity that consumes or produces gases within a lake; and
• gas composition of groundwater and surface water entering a lake.
