Global Estuarine Nitrous Oxide Distribution
Certificate(s): Global Health and Health Policy
I spent the summer studying the production of nitrous oxide in global estuarine and coastal regions. Nitrous oxide is an ozone-depleting agent with about 300 times the warming potential of carbon dioxide. Measurements of nitrous oxide in global estuaries vary considerably, however, due to environmental and anthropogenic factors. I worked with Weiyi Tang to read, extract, compile and analyze data from 80 published papers covering over 100 estuaries to identify the factors contributing to the variability in global nitrous oxide distribution. After contacting the authors of the published works, we compiled their individual data sets into a central nitrous oxide estuarine database. We then used the data to create a new global estuarine nitrous oxide distribution map. Additionally, the data allowed us to perform correlation analyses between nitrous oxide and other environmental factors on a global scale. Through this internship, I gained skills in data analysis, presentation and communication, and I was introduced to the amazing world of biogeochemistry and environmental science.
