Marine Microbial Genomics and Biogeochemistry

西北大西洋（NWA）是海洋的一个高产地区，支持着重要的渔业。在食物链底部的浮游植物和其他微生物为更高的营养水平提供食物和能量。全球变暖正在引起西北西海的快速变化，导致氧气减少、海流模式改变、海面温度上升和分层，从而导致生产力和营养供应的变化。本研究利用时间序列观察，结合实验和新的组学方法，研究了这些变化对微生物群落的响应，特别是氮循环和n2固定。

The Northwest Atlantic (NWA) is a highly productive region of the ocean, supporting important fisheries. The phytoplankton and other microbes at the base of the food chain supply food and energy to higher trophic levels. Global warming is causing rapid changes in the NWA, leading to decreasing oxygen, changing current patterns, increases in sea surface temperature and stratification that are leading to changes in productivity and in nutrient supply. The research investigates the response of these changes on the microbial community, using time-series observations, coupled with experiments and novel omics approaches, focusing on the nitrogen cycle and N2-fixation in particular.
