项目摘要

P.I. Chant, Robert (Rutgers) Proposal #: 0238957Proposal Title: COLLABORATIVE RESEARCH: Lagrangian studies of the transport, transformation, and biological impact of nutrients and contaminant metals in a buoyant plume Project Summary The PIs propose a coordinated program of field and numerical experiments to examine processes that control the fate and transport of nutrients and chemical contaminants in the Hudson River plume. Urban estuarine plumes such as this one represent a major pathway for the transport of nutrients and chemical contaminants to the coastal ocean. The fates and transports of this material are controlled not only by the plume dynamics but also by biological and chemical processes coupled to the dynamics of the plume. To investigate these processes, the PIs propose to conduct a series of dye experiments along with continuous underway chemical and biological sampling using a towed vehicle. These experiments will occur within the framework of the LEO-15 Observatory to enable interpretation of the dye study by placing the Lagrangian surveys in context with shelf-wide observations from satellite imagery, surface currents and far-field subsurface hydrography. LEO-15 will be augmented by a cross shelf array of moored instruments to provide detailed estimates of subtidal circulation, stratification and Reynold stresses. In addition, data-assimilative numerical simulations will provide high resolution and realistic hindcasts of the coastal ocean during the field experiments. The modeling will assimilate the dye-tracer data into a 3-D coastal circulation model and guide future efforts to assimilate other tracers into circulation models with complex sources and sinks. The major aims of this work are to distinguish between physical processes that transport/mix material in a buoyant plume from biological and chemical transformation processes as well as the quantification of biological and chemical interactions in a Lagrangian perspective to provide a means to assess their importance in determining the fate and transport of nutrients and chemical contaminants in a buoyant plume. The proposed experimental plan will contrast the response of physical, biological, and chemical processes in the Hudson plume during upwelling and downwelling conditions. A major outcome of this work will be the determination of the extent and biological impact of contaminants in the plume along the New Jersey coast and Middle Atlantic Bight and will improve the ability to predict the fate and transport of contaminants and the rate that they enter the base of the food chain in the coastal ocean.
P.I. Chant,Robert(Rutgers)提案编号:0238957提案标题:合作研究:浮羽流中营养物质和污染物金属的运输、转化和生物影响的拉格朗日研究项目摘要PI提出了一个协调的实地和数值实验计划,以检查控制哈德逊河羽流中营养物质和化学污染物的命运和运输的过程。像这样的城市河口羽流是营养物质和化学污染物向沿海海洋输送的主要途径。这种物质的命运和运输不仅受羽流动力学的控制,而且还受与羽流动力学相结合的生物和化学过程的控制。为了调查这些过程,PI建议进行一系列染色实验,沿着使用拖曳车辆进行连续的化学和生物采样。这些实验将在LEO-15天文台的框架内进行,以便能够通过将拉格朗日测量与从卫星图像、表层水流和远场地下水文地理学获得的整个大陆架观测相结合,对染料研究进行解释。LEO-15将增加一个跨大陆架系泊仪器阵列,以提供潮下环流、分层和冷应力的详细估计。此外,数据同化数值模拟将在实地试验期间提供沿海海洋的高分辨率和现实的后报。该模型将把染料示踪剂数据同化到三维沿海环流模型中,并指导今后将其他示踪剂同化到具有复杂源和汇的环流模型中的工作。 这项工作的主要目的是区分物理过程中的运输/混合材料的浮力羽流从生物和化学转化过程,以及量化的生物和化学相互作用的拉格朗日的角度来看,以提供一种手段来评估其重要性,在确定的命运和运输的营养物质和化学污染物的浮力羽流。拟议的实验计划将对比物理,生物和化学过程中的哈德逊羽在上升流和下降流条件下的反应。这项工作的一项主要成果将是确定新泽西海岸和中大西洋湾沿着羽流中污染物的范围和生物影响,并将提高预测污染物的命运和迁移以及它们进入沿海海洋食物链底部的速度的能力。
