This summer, I studied ocean circulation dynamics while interning with Princeton’s Department of Atmospheric and Oceanic Sciences. The density of seawater is determined by its temperature and salinity content, but this relationship is nonlinear. When two bodies of water of the same density are mixed, they create a new, denser body of water. Analyzing data output from models, I looked into how these nonlinearities in the equation of state affect ocean circulation, the distribution of nutrients in the ocean, and ultimately ocean biogeography. All of these factors have a greater significance beyond oceanography as they can affect Earth’s climate as a whole. Through this experience, I gained a deeper insight into general ocean circulation and became much more familiar with MATLAB. I plan to continue research in this topic for my junior independent project.
