Climate-related shifts in phytoplankton assemblages may have profound implications for oceanic feedbacks on the atmosphere, and for human use of marine resources. Particular algal groups are largely responsible for crucial processes like vertical carbon export, biogenic calcification and silicification, production of climatically active gases like dimethylsulfide (DMS), and for sustaining food webs that lead to economically valuable higher trophic levels. The Drs. Hutchins and DiTullio will investigate potential climate change impacts on algal community structure and biogeochemistry during the North Atlantic Spring Bloom, a regime that is ideal for determining how changing ocean conditions may affect both calcareous and siliceous algae. The PIs will work closely with CarboOcean a major European Union funded activity led by investigators from the Alfred Wegener Institute. This will include exchanges of cruises between the two groups, collaborative shipboard experiments, and modeling efforts using joint results. Graduate student and post-doctoral training will be included as part of the interdisciplinary and international activities.

浮游植物组合中与气候相关的变化可能对海洋对大气的反馈以及人类对海洋资源的利用产生深远的影响。 特定的藻类群体在很大程度上负责关键过程，如垂直碳输出，生物钙化和硅化，产生气候活性气体，如二甲基硫（DMS），并维持食物网，导致经济上有价值的更高的营养水平。 哈钦斯博士和DiTullio博士将在北大西洋春季水华期间研究气候变化对藻类群落结构和生物地球化学的潜在影响，这是一个非常适合确定海洋条件变化如何影响钙质和硅质藻类的制度。 PI将与CarboOcean密切合作，CarboOcean是由Alfred Wegener研究所的研究人员领导的欧盟资助的主要活动。 这将包括两个小组之间的巡航交流，合作船上实验以及使用联合结果的建模工作。 研究生和博士后培训将作为跨学科和国际活动的一部分。
