U.S. GLOBEC: Biological and Physical Evidence of Source Regions and Transport Patterns of Zooplankton on Georges Bank

为了解决浮游动物在海洋中的扩散问题，特别是确定在乔治滩繁殖的卡兰纳斯（Calanus finmarchicus）的来源，我们对北大西洋西部桡足类的种群遗传特征和水运模式的水文参数进行了综合分析。我们的目标是利用生物和物理证据，记录影响乔治滩桡足类年增长的来源和运输模式。对于群体遗传学的努力，我们正在确定遗传变异的水平，遗传上不同群体的细分证据，以及基因流动和散布在采样域的定量估计。在水文研究方面，我们利用历史观测资料提供了一个气候学角度的水团结构和变化。主要档案是大西洋渔业调整计划（AFAP）水文数据库。我们还将获得新的NMFS数据（不在NODC中），以便与我们正在制作的气候分析进行比较。

To address questions of zooplankton dispersal in the ocean, especially identification of sources of Calanus finmarchicus for recruitment to Georges Bank, we are using an integrated analysis of the population genetic character of the copepod and the hydrographic parameters of water mass and transport patterns in the western N. Atlantic. Our goal is to document, using biological and physical evidence, the sources and transport patterns that influence the annual increase of copepods on Georges Bank. For the population genetics effort, we are determining levels of genetic variation, evidence for sub-division into genetically distinct populations, and quantitative estimates of gene flow and dispersal across the sampling domain. For the hydrographic effort, we are using historical observations to provide a climatological perspective of water mass structure and variability. The primary archives are the Atlantic Fisheries Adjustment Program (AFAP) hydrographic database. We will also have access to the new NMFS data (not in NODC) for comparison with the climatological analyses we are producing.
