Laboratory test showed that the method is capable of measuring ammonia at 0.02 uM level. On-board measurement indicated that a small maximum signal of less than 0.1 uM ammonia was observed at ca. 60 m in the South China Sea.application/pdf121346 bytesapplication/pdfzh-TW國立臺灣大學海洋研究所氨氮生物密集層Ammoniasub-surface layerreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/14773/1/892611M002034.pdf
