从空间对海水进行可见光谱辐射测量，通常称为海洋颜色测量，可提供对表层浮游植物和其他光学活性成分的高时间分辨率的概况，这是任何其他技术所无法比拟的。然而，对海洋颜色的现场观测对卫星的成功至关重要，它可以跟踪辐射计的校准情况并验证大气校正算法。由于商业实地辐射计的费用很高，以及海洋实地工作的相关费用也很高，海洋颜色科学家因缺乏高质量的实地辐射测量观测而受到困扰，特别是在偏远地区。在这篇透视文章中，我们强调了通过利用超级游艇来增加海洋颜色原位观测数量的潜力。使用开放的数据处理软件，我们表明，使用超级游艇收集的自动海洋颜色数据可用于海洋颜色卫星的验证，其结果与传统的验证研究相当。接触富有的公民科学家可能有助于填补我们监测海洋颜色的能力空白。
Visible spectral radiometry of seawater, often referred to as ocean colour, from space, provides a synoptic view of surface phytoplankton, and other optically-active constituents, at high temporal resolution, that is unsurpassed by any other technology. Yet, in-situ observations of ocean colour are critical to the success of the satellite, tracking the calibration of the radiometers and validating atmospheric correction algorithms. Owing to the high cost of commercial field radiometers, as well as the high costs associated with ocean-based field work, ocean colour scientists are plagued by a sparsity of high quality in-situ radiometric observations, particularly in remote regions. In this perspective article, we highlight potential to increase the number of in-situ observations of ocean colour by harnessing superyachts. Using openly-available data processing software, we show that automated ocean colour data collected using a superyacht can be used for the validation of an ocean colour satellite, with comparable results to traditional validation studies. Reaching out to wealthy citizen scientists may help fill gaps in our ability to monitor the colour of the ocean.
