Acquisition and Operation of an Array of High Frequency RADARs for Observing Surface Currents in Hawaii Coastal Waters

9724464弗莱特夏威夷大学将购买和安装一组高频多普勒雷达，能够测绘距离达70公里的表层洋流，操作该阵列，分析产生的数据，并生产各种支持海洋学研究的产品。雷达阵列将提供分辨率为3公里的电流时间序列，数据将经常更新，以便为研究动态过程提供良好的空间和时间复盖面。雷达获取的海流数据将与传统海流计的数据进行比较。PIS预计，在理解过程方面将取得进展，如岛屿周围的潮汐传播、岛屿滞留波的形成和衰减以及岛屿背风处的涡流产生。对生物过程的研究，如将远洋幼虫招募到成年沿海生境，需要洋流平流的信息，也将受益于这一新能力。该项目的一个重要副产品将是实时传播表层海流地图，以帮助那些需要这种数据的人，如船舶路线、海岸区管理、减少污染、近岸沉积物运输和其他用途。该大学正在分担这一项目的费用。

9724464 Flament The University of Hawaii will acquire and install an array of high frequency Doppler radars, capable of mapping surface ocean currents within a distance of up to 70 km, operate the array, analyze the resulting data, and produce various products that will support oceanographic research. The radar array will provide time series of currents at a resolution of 3 km and data will be updated often enough to provide good spatial and temporal coverage for studying dynamic processes. Radar-derived data on currents will be compared with data from traditional current meters. The PIs anticipate that advances will be made in understanding processes such as tidal propagation around islands, formation and decay of island-trapped waves, and eddy generation in the lee of islands. Studies of biological processes such as recruitment of pelagic larvae to adult coastal habitats, requiring information on advection by ocean currents will also benefit from this new capability. An important byproduct of this project will be real-time dissemination of surface current maps to aid those with a requirement for such data, such as ship routing, coastal zone management, pollution abatement, nearshore sediment transport and other uses. The University is cost-sharing this project.
