项目摘要

Internal waves, which are waves formed between two layers of a stratified water column, are observed to propagate towards the coastline in most continental shelve regions. As these waves shoal, or are slowed by bottom friction, when entering into water depths of approximately one-half of the wave amplitude, their interaction with the bottom causes these waves to undergo transformations. Observations of across-shore transport and nutrient and plankton mixing suggest that nonlinear internal waves (NLIWs) play a critical role in the maintenance of some inner shelf benthic communities. However, the across-shore transport length scales, the dispersion rates and the fluxes of buoyancy, momentum and energy, and, thus, the potentially important influence of these waves on coastal circulation and ecosystems, have not yet been quantified. Oceanographers from Oregon State University and the University of North Carolina, with support from the Woods Hole Oceanographic Institute, will use a combined observational and numerical approach to quantify transport, dispersion, buoyancy and momentum fluxes, and flux divergences of shoaling NLIWs and determine their influence on the low-frequency circulation and density field in Massachusetts Bay. Their field observations will include deployments of a mooring array to quantify nonlinear internal wave fluxes, rapid shipboard surveys to study the evolution of individual waves from their generation point, through the region of shoaling, and to their demise near the coast, and dye injections and shipboard tracking to quantify scales of across-shore transport and rates of dispersion. In addition to field observations, a 'state-of-the-art', adaptive grid, nonhydrostatic, numerical model will be used to simulate nonlinear internal wave generation and evolution to compare the numerical output with the field observations and understand the detailed, three-dimensional evolution of these waves. Studying this process will provide an objective assessment of the significance of NLIWs relative to other physical processes in the coastal ocean. Understanding the mechanisms which transport and disperse water-borne materials (e.g., nutrients, pollutants, plankton) in the coastal ocean is a high priority objective for coastal physical oceanographic research and can have direct influence on environmental management.
内波是在分层水柱的两层之间形成的波,在大多数大陆架区域被观察到向海岸线传播。当这些波浪浅滩化或因底部摩擦而减慢时,当进入大约一半波幅的水深时,它们与底部的相互作用会导致这些波浪发生转变。跨岸运输和营养盐和浮游生物混合的观测表明,非线性内波(NLIWs)在维持一些内陆架底栖生物群落中发挥着至关重要的作用。然而,跨海岸的运输长度尺度,分散率和浮力,动量和能量的通量,因此,这些波对沿海环流和生态系统的潜在重要影响,尚未量化。来自俄勒冈州州立大学和北卡罗来纳州大学的海洋学家在伍兹霍尔海洋研究所的支持下,将使用观测和数值相结合的方法来量化浅化NLIW的传输、分散、浮力和动量通量以及通量发散,并确定它们对马萨诸塞州湾低频环流和密度场的影响。他们的实地观测将包括部署一个系泊阵列,以量化非线性内波通量;快速船上调查,以研究单个波浪从其生成点到浅滩区域的演变,以及它们在海岸附近的消亡;染料注入和船上跟踪,以量化跨海岸运输的规模和分散率。除了现场观测外,还将使用“最先进的”自适应网格非流体静力数值模型来模拟非线性内波的产生和演变,以将数值输出与现场观测进行比较,并了解这些波的详细三维演变。研究这一过程将提供一个客观的评估的意义,NLIWs相对于其他物理过程在沿海海洋。了解运输和分散水性材料的机制(例如,沿海海洋中的营养物、污染物、浮游生物)是沿海物理海洋学研究的一个高度优先目标,并可对环境管理产生直接影响。
