项目摘要

The overall goal of this project is to understand the processes that regulate the large-scale distribution and abundance of Calanus finmarchicus, a keystone species of the North Atlantic ecosystem. The investigators hypothesize that three main population centers in the North Atlantic are quasi-distinct and selfsustaining. This hypothesis will be tested with combined physical-biological modeling and genetic analysis of C. finmarchicus populations. The modeling approach is to assimilate observations of C. finmarchicus from the Continuous Plankton Recorder (CPR) into the North Atlantic Regional Ocean Modeling System using the adjoint method. The first phase of the project will be to investigate the mean seasonal cycle based on monthly mean CPR data together with the climatological mean circulation. The inverse model solution will be diagnosed to quantify the interconnectivity between the three population centers. Molecular population genetic analysis will yield independent estimates of the rates of exchange between the gyres, which will be compared with model predictions. This assessment of the climatological mean seasonal cycle will set the stage for a study of interannual variability, with particular emphasis on changes in the mean state of the system in association with the North Atlantic Oscillation.The intellectual merit of this effort includes its interdisciplinary approach (physics and biology) and integrated analysis (adjoint modeling and molecular population genetics), which can provide new insights into complex oceanographic phenomena, such as ocean basin-scale processes, that are difficult or impossible to observe directly. Broader impacts of the proposed research will include international collaboration, as well as training of both undergraduate and graduate students. The project will use the outreach capacity of the "Census of the Marine Zooplankton," a Census of Marine Life (CoML) field project led by A. Bucklin, to ensure broad dissemination of results to researchers, students, and educators. This project will produce a video, contribute to CoML synthesis publications, and produce researcher interviews for the CoML web site.
该项目的总体目标是了解调节北大西洋生态系统的关键物种--Finmarchicus的大规模分布和丰度的过程。研究人员假设,北大西洋的三个主要人口中心是准独立和自我维持的。这一假说将用物理-生物模型和遗传分析相结合的方式进行验证。模式的方法是利用伴随方法将来自连续浮游生物记录仪(CPR)的Finmarchicus观测同化到北大西洋区域海洋模式系统中。该项目的第一阶段将根据每月平均CPR数据和气候平均环流调查平均季节周期。将对反向模型解进行诊断,以量化三个人口中心之间的相互联系。分子群体遗传分析将产生对回旋之间交换率的独立估计,并将其与模型预测进行比较。这种对气候平均季节周期的评估将为研究年际变化奠定基础,特别强调与北大西洋涛动有关的系统平均状态的变化。这一努力的智力优势包括其跨学科方法(物理和生物学)和综合分析(联合建模和分子种群遗传学),这可以为难以或不可能直接观察到的复杂海洋现象提供新的见解。拟议研究的更广泛影响将包括国际合作,以及对本科生和研究生的培训。该项目将利用A.Bucklin领导的海洋生物普查(CoML)实地项目“海洋浮游动物普查”的推广能力,确保将结果广泛传播给研究人员、学生和教育工作者。该项目将制作一段视频,为CoML合成出版物做出贡献,并为CoML网站制作研究员访谈。
