9806379BeardsleyFrontal exchange processes over eastern Georges Bank and the adjacent Northeast Channel-Browns Bank region will be investigated using a combination of field work and modeling. The field work features moored array measurements, Lagrangian. drifter observations, and several physical/biological surveys, and will focus on the winter-spring period when cross-front transport of water and biota, especially Calanus finmarchicus from the Gulf of Maine across the northern flank frontal system (NF'FS) and larval cod and copepods via Scotian Shelf Water cross-overs, are thought to be most critical for the survival and recruitment of the target species on Georges Bank. The model work will be directed towards an improved description and understanding of the NFFS and other fronts over the eastern end of the Bank with a focus on the mechanisms for transport of water, nutrients and biota from the Gulf of Maine and the Scotian Shelf to the Northeast Peak and southernflank of Georges Bank. Comprehensive analysis of the observational and model results will lead to new understanding and insight into the physical processes driving frontal exchange over eastern Georges Bank and their biological consequences.

9806379比尔兹利将采用野外工作和模拟相结合的方法，研究乔治斯滩东部和邻近的东北海峡-布朗滩地区的锋面交换过程。野外工作的特点是系泊阵列测量，拉格朗日。该项目将进行漂流观测和若干物理/生物调查，重点将放在冬春季，此时水和生物群的跨界运输，特别是来自缅因湾的Finmarchicus穿越北侧锋面系统的Calanus finmarchicus，以及通过斯科特大陆架水域跨界的幼体鳕鱼和桡足类，被认为对乔治斯海岸目标物种的生存和招募最为关键。示范工作的目的将是改进对NFFS和西岸东端其他前线的描述和了解，重点是水、营养物质和生物群从缅因湾和斯科特大陆架到乔治斯海岸东北峰和南侧的输送机制。对观测结果和模式结果的综合分析将有助于对推动乔治斯海岸东部锋面交换的物理过程及其生物学后果有新的理解和见解。
