小行星9724464 夏威夷大学将购置并安装一系列 能够测绘海洋表面的高频多普勒雷达 在70公里范围内的电流，操作阵列， 分析产生的数据，并生产各种产品， 将支持海洋学研究。 雷达阵列将 提供分辨率为3公里的海流时间序列和数据 将经常更新，以提供良好的空间和时间 研究动态过程的覆盖范围。 雷达数据 电流将与传统电流的数据进行比较， 米PI预计将在以下方面取得进展： 了解岛屿周围的潮汐传播等过程， 岛陷波的形成和衰减以及涡流的产生 在岛屿的背风处。生物过程的研究，如 将浮游幼虫补充到成年沿海生境， 需要洋流平流的信息， 受益于这一新能力。 这个项目的一个重要副产品将是实时的 传播表面电流图，以帮助那些 对此类数据的要求，如船舶航线、沿海区 管理、减少污染、近岸沉积物运输和 其他用途。联合国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.
