Abstract

Methane (CH4) emission from the aquatic environment is considered as one of the sources of greenhouse gas contributes significantly important to the global warming. For measuring continuously the methane emission from the water-atmospheric interface an automatic sampling and measurement system using floating chamber integrated methane sensor (Automated Floating Chamber integrated Methane Sensor - AFCMS) has been fabricated including the control and PIC datalogger boards with a lower cost than a commercial product. The floating chamber integrated a methane sensor (Panterra, Neodym Technologies, Canada) which works well not only on the quiet water surface but even on the oscillated one. The sensor (coded 1501-1) has a low LOD = 0.45 ppm and a good linearity (R2 = 0.9947) of methane concentration ranging from 2 to 30 ppm. AFCMS system shows a good performance of the equipment deployment for sampling and measuring the methane emissed from the urban canals.
