摘要：使用海洋站 P 的两个数据井乘波器收集的并发数据来检查生物污垢对波浪测量浮标的影响：一个在 26 个月的部署结束时出现严重生物污垢，另一个是新部署的且干净。这些影响仅限于浮标的高频响应，并通过比较水平和垂直位移的频谱“检查因素”来正确诊断。对生物污垢期间频率响应的渐进变化的简单预测可再现随时间变化的检查因素。有效波高、峰值周期、平均周期和峰值方向等大量统计参数仅受到生物污垢的轻微影响，因为受污染的频率在整个比较数据集中具有非常低的能量。
AbstractThe effects of biofouling on a wave measurement buoy are examined using concurrent data collected with two Datawell Waveriders at Ocean Station P: one heavily biofouled at the end of a 26-month deployment, the other newly deployed and clean. The effects are limited to the high-frequency response of the buoy and are correctly diagnosed with the spectral “check factors” that compare horizontal and vertical displacements. A simple prediction for the progressive change in frequency response during biofouling reproduces the check factors over time. The bulk statistical parameters of significant wave height, peak period, average period, and peak direction are only slightly affected by the biofouling because the contaminated frequencies have very low energy throughout the comparison dataset.
