利用低海拔(500米)紧凑型航空光谱成像仪高光谱测量，研究了兰吉罗环礁(法属波利尼西亚)蓝藻席的色素沉着。反射吸收系数的二阶和四阶导数中的峰可以用叶绿素和类胡萝卜素色素来解释，这两种色素是通过高压液相色谱独立鉴定的。从空中测量中也检测到藻胆素色素。这项研究证实了导数光谱学从活体到高分辨率遥感测量的延展性，用于海洋生物和地球化学调查。
The pigmentation of a cyanobacterial mat located in Rangiroa atoll (French Polynesia) was characterized using low‐altitude (500 m) Compact Airborne Spectrometer Imager hyperspectral measurements. Peaks in second and fourth derivatives of the reflective absorptance can be explained by chlorophyll and carotenoid pigments, which were independently identified by high‐pressure liquid chromatography. Phycobilin pigments were also detected from airborne measurements. The study confirms the extensibility of derivative spectroscopy from in vivo to highresolution remote sensing measurements for biology and geochemistry investigations in marine communities.
