Microorganisms form the base of marine food webs, determine current and future patterns of ocean productivity, and both respond to and influence global biogeochemical cycles. To understand the role of microorganisms in changing biogeochemical cycles, the Chairs research program will utilize traditional and cutting edge biogeochemical approaches, including nutrient analyses, optical sensors, stable isotopes, and Fourier transform ion cyclotron resonance mass spectrometry. Coupling these tools with both manipulative studies and large-scale field sampling programs, the Chair will quantify how changes in the physiochemical environment influence the concentration, composition, and biological cycling of marine inorganic and organic macronutrients.

微生物构成了海洋食物网的基础，决定了当前和未来的海洋生产力模式，并响应和影响全球生物地球化学循环。为了了解微生物在改变生物地球化学循环中的作用，主席研究计划将利用传统和前沿的生物地球化学方法，包括营养物分析、光学传感器、稳定同位素和傅里叶变换离子回旋共振质谱法。将这些工具与操作性研究和大规模现场采样计划相结合，主席将量化理化环境的变化如何影响海洋无机和有机大量营养素的浓度、组成和生物循环。
