The goal of my project was to analyze new data from below the sea ice in the Southern Ocean to better understand the sea ice gas exchange between the ocean and the atmosphere. The data came from the Argo project, which has released nearly 4,000 floats worldwide that collect temperature and salinity characteristics of our oceans. We found that previously held models of how sea-ice gas exchange works needed revision as the model seemed to consistently deviate from observed data. Progress in the project was quite easy because of the smooth, consistent communication I had with my mentor in discussing the direction of the project and the results from the previous day. I learned a lot about oceanic sciences, as well as how to program in MATLAB, which is an invaluable skill in the sciences. This internship got me interested in continuing to study the ocean. I plan to use this project as the basis of my junior thesis and perhaps of similar projects for future theses.
