Introduction: Scientists use water sampling for many reasons. They tend to observe different qualities of water for many reasons as well. At JU, we are blessed with the St. John’s river as our backyard and it is used for commercial activities so it is important for scientists to keep an updated record of how water is changing in different ways; like if it’s from environmental or from humans. For two weeks, we explored the St. John’s River on the MSRI pontoon; we have been conducting our own water quality samples and also seeing how the river is used. We tested everything from secci depth to floor samples, but the floor samples were put to a halt when the ponar grab was snagged on an artificial reef on the first day; but we also measured pH, D.O, Temperature, and salinity at all of the sites we visited. Depths differentiated between every site and because of this we measured every 50 cm until river bottom using the YSI. It took two days to perform our site

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
