I studied the seasonal variability of phytoplankton productivity in the subtropical Pacific Ocean. I used the programming language Python to analyze data collected by autonomous Argo floats deployed in the Southern Ocean that estimate chlorophyll and particulate organic carbon levels at depths of up to 2,000 meters. I mainly looked at how changes at the depth of the mixed layer — the portion of the ocean’s top layer that experiences turbulence — influence the seasonal cycles of phytoplankton blooms. Because the existing literature on this topic is very limited, I felt like I made significant contributions to the world of physical oceanography. In nine weeks, I learned an incredible amount not only about the ocean, but also about coding and data analysis. I also partook in a 10-day research cruise to collect data for future studies. I am now even more certain I want to continue doing research after I graduate and the skills and experiences from my internship will be huge assets in my application to graduate school.
