Collaborative Research: US/EC Collaboration on Potential Climate Change Impacts on Algal Community Structure and Biogeochemistry During the North Atlantic Spring Bloom

与气候有关的浮游植物组合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。特定的藻类主要负责垂直碳输出、生物钙化和硅化等关键过程，产生二甲基硫化物(DMS)等气候活性气体，以及维持导致经济价值更高的营养水平的食物网。Hutchins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，这一制度非常适合确定不断变化的海洋条件可能如何影响钙质和硅质藻类。投资促进机构将与欧洲联盟资助的由阿尔弗雷德·韦格纳研究所的调查人员领导的一项主要活动CarboOcean密切合作。这将包括两个小组之间的巡航交流，合作的船上实验，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。

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.
