I performed research concerning gas exchange across the ocean’s air-sea boundary. Quantifying gas flux is paramount in measuring gas concentrations in the ocean, and gas concentrations help us calculate net community production. Net community production is a primary control on carbon distribution between the atmosphere and the ocean and, thus, has an impact on global warming. However, new air-sea gas parameterizations indicate the importance of explicitly including bubble injection to calculate gas fluxes. The purpose of my project was to assess the impact of adding a bubble-injection parametrization to the model of air-sea gas exchange. To analyze biogeochemical-model output, I programmed modules in MATLAB and designed illustrative graphs. I had an absolutely incredible experience working in the Program in Atmospheric and Oceanic Sciences (AOS), learning MATLAB, and meeting faculty and students from fields outside of what I usually study. Working in AOS introduced me to data analysis, and it taught me the importance of these skills across several different disciplines.
