4. What can we learn about Narragansett Bay by measuring dissolved oxygen?

Dissolved oxygen in the surface water can tell us about photosynthesis and the air-sea exchange. In the deep water, dissolved oxygen is a good indicator of water quality. Low dissolved oxygen indicates a stressed environment. Water with low dissolved oxygen cannot support healthy communities of plant and animal life.
