Abstract: Method for reducing ocean temperatures and enhancing alkalinity, the method cited here both reduces ocean acidification and helps lower ocean water temperature by reflecting the sun with a froth flotation of bubbles, a method when used in areas of coral reef improves the conditions necessary for coral reef growth, the method consists of first locating a dispersing source, such as a boat or other device able to position itself over a coral reef, or in any ocean section, second creating a froth flotation of bubbles with alkaline and other minerals attached, and then third dispersing the froth flotation consisting of bubbles with minerals attached, over the coral reefs, and then having the bubbles to reflect the sun rays to lower ocean temperature, the method also allows the alkaline minerals to disengage from the bubbles over time, reducing the acidification levels in the ocean and around coral reefs.
