Sarah Weber is a new PhD student in Biological Oceanography at the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) in Germany, where she is a part of Dr. Maren Voss’s working group. Sarah has a general interest in marine biogeochemistry, with a focus on nitrogen fixation (diazotrophy). For her thesis, Sarah will be exploring the roles of the Mekong River and Monsoon-induced upwelling on diazotrophy in the South China Sea. She will also conduct onboard experiments to analyze nitrogen transfer within diatom-diazotroph associations (DDAs) using nitrogen stable isotopes.
Prior to the start of her PhD, Sarah was a Masters student and Research Scientist with Dr. Joseph Montoya at the Georgia Institute of Technology. There she studied the influence of the Amazon River on offshore diazotrophy, as well as the impact of the Deepwater Horizon oil spill on the nitrogen and carbon cycles of the Gulf of Mexico.
