基于全球定位卫星（GPS）的小型、轻量级和易于部署的微型波浪浮标（mini-浮标）越来越受欢迎。大多数被部署为拉格朗日漂船，因此它们在工程应用中的实用性，需要近岸系泊，仍然是一个问题。我们评估了五个系泊迷你浮标在北卡罗莱纳州鸭子海岸的性能，现场研究设施（FRF）。我们在两次部署中收集了8个月的数据；首先在FRF的8米阵列附近，然后在17米深度的Datawell乘波器附近。我们部署了一个声学多普勒电流分析器（ADCP）来测量波浪和电流，并将其与附近的操作系统进行比较，作为迷你浮标的性能基准。迷你浮标表现良好，波浪频谱和频谱参数的统计数据与基准相似，方向参数的统计数据优于基准。然而，微型浮标通信有时会因倾斜或淹没而中断，表现为低频噪声或下降。如果系泊系紧，受到风或水流的影响，并且由于缠绕的线或较浅的深度而恶化，那么迷你浮标更容易受到通信问题的影响。总的来说，这些问题很少见；因此，小型浮标被发现适合于许多应用。
Small, lightweight, and easy-to-deploy Global Positioning Satellite (GPS)-based miniature wave buoys (mini-buoys) are increasing in popularity. Most are deployed as Lagrangian drifters, so their utility for engineering applications, requiring a nearshore mooring, has remained in question. We evaluated the performance of five moored mini-buoys off the coast of Duck, North Carolina at Field Research Facility (FRF). We collected 8 months of data over two deployments; first near the FRF’s 8-m array and then near a Datawell Waverider in 17-m depth. We deployed an Acoustic Doppler Current Profiler (ADCP) that measured waves and currents, and compared it to the nearby operational system as a performance benchmark for the mini-buoys. The mini-buoys performed well, with statistics similar to the benchmark for wave frequency spectra and spectral parameters, and they outperformed the benchmark on directional parameters. However, mini-buoy communication was sometimes interrupted by tilting or submersion, which manifested as low-frequency noise or drop-outs. If a mooring was taut, forced by winds or currents and exacerbated by tangled lines or shallower depths, then mini-buoys were more susceptible to communication issues. Overall, these issues were rare; thus, mini-buoys were found to be appropriate for many applications.
