Dissolved Oxygen Over Time Data

You can also explore this dataset on TUVA, an interactive graphing platform.


Dissolved oxygen (D.O.) is an important measure of water quality and can be used to predict information about the local community of organisms. For instance, D.O. levels can limit the types of animal species that can survive in a particular area. They can also be used to study trends in photosynthesis levels within a body of water. This dataset captures the levels of D.O. in the Hudson River at Germantown over the course of a 5-day period. D.O. sampling was performed every 15 minutes.
