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.

为了解决浮游动物在海洋中的扩散问题，特别是确定将被招募到乔治斯海岸的Finmarchicus Calanus的来源，我们正在综合分析该桡足类的种群遗传特征以及北大西洋西部的水团和输送模式的水文参数。我们的目标是利用生物和物理证据，记录影响乔治斯海岸桡足类年增长的来源和运输模式。对于群体遗传学工作，我们正在确定遗传变异的水平，细分为遗传上不同的群体的证据，以及对基因在采样域中流动和扩散的定量估计。对于水文测量工作，我们利用历史观测来提供水团结构和可变性的气候学视角。主要档案是大西洋渔业调整方案(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。
