海洋研究科学家往往希望知道海洋所含的有机分子，比如海水的污染情况或研究煤的燃烧对空气中碳成分的影响。为进行这种研究，通常是收集几小瓶海水，在实验室内对其进行分析。但麻萨诸塞大学的研究人员正用一种不同的技术，即便携式光纤光谱荧光技术（见图）。用光纤荧光计测 Marine research scientists often want to know about the organic molecules in the oceans, such as seawater pollution or the impact of coal combustion on the carbon content of the air. To carry out such a study, it is common to collect a few small bottles of seawater and analyze them in the laboratory. But researchers at the University of Massachusetts are using a different technique, the portable fiber-optic fluorescence spectroscopy (see photo). Measured with optical fiber fluorometer
