Is that Bo? No, it’s DO: Eutrophication.

Abstract

Eutrophication is the process that a body of water acquires additional nutrients (Smith et al., 1999). Sometimes this process lead less oxygen of a body of water also warmer water temperatures can also cause lower level of oxygen. We hypothesize that if we heat up and pollute a water sample, and then there will be less dissolved oxygen than in a regular, non-polluted heated water sample. We test this by polluting and heating different samples of water and measuring their dissolved oxygen level. From the information we gathered we saw that a water sample that was heated and not polluted had less dissolved oxygen.
