My GLOBE project was inspired by and based around Narragansett Bay. It is local for me, and I learned at summer camp about it. Narragansett Bay connects the Seekonk river and the Atlantic Ocean. The water in the middle is brackish, a mix of Seekonk river’s freshwater and the salty ocean water. I wondered if the pH, or acidity, changes in the Bay, while I was thinking about doing my project on the salinity. My research question became: How does the salinity change, and does the pH change in Narragansett Bay? I wanted to know if the salinity had a sort of drop-off point where it got much higher, or if it rose at a steady rate. I found that the salinity increases, as expected, and that the pH lowers.
