密集的浮游生物水华（俗称“赤潮”）正在成为沿海沃茨日益重要的现象。这封信展示了如何使用欧洲卫星传感器MERIS（中分辨率成像光谱仪）来检测705 nm附近的离水辐射光谱中的峰值，这对某些类型的水华提供了更具体的响应。图像和光谱，来自MERIS场景中的小面积有这种反应。其中一个区域是一个养鱼场所在地，通过表面观察和测量证实了水华状况。观察到的光谱模型的结果进行比较，以证明这些反应是如何产生的。对来自世界其他地区的数据的检查显示出美国和欧洲沃茨的类似特征。
Intense plankton blooms ( colloquially called 'red tides') are becoming an increasingly important phenomenon in coastal waters. This Letter shows how the European satellite sensor MERIS ( Medium Resolution Imaging Spectrometer) can be used to detect a peak in the optical spectrum of water-leaving radiance near 705nm which provides a more specific response to some types of these blooms. Images and spectra are presented, derived from a MERIS scene where small areas have this response. One such area is at the site of a fish farm where bloom conditions were confirmed by surface observations and measurements. The observed spectra are compared to model results to demonstrate how these responses arise. Inspection of data from other parts of the world shows similar features in US and European waters.
