MARSITE 1 - Methane meter dataset


Instrument: Franatech METS Methane Sensor
Investigator: Giuditta Marinaro (INGV)
Project: MARSITE
Observatory: SN-4

Abstract: The Methane sensor provides two output analogue channels (Vmet, Vt) which are sampled at 1Hz by a dedicated Analog To Digital Converter of the SN4 station. From (Vmet, Vt) through a calibration formula, the dissolved methane concentration in sea water can be computed. The sensor has been used with the pump.

Purpose: The purpose of the methane sensor installation on the SN4 observatory is to monitor the variation of methane gas dissolved in sea water. The installation site is rich in gas seepage from seafloor, thus the variation in methane dissolved concentration can provide a mean to monitor gas emission from seabed. This sensor enable us to study methane gas emission dynamic and its correlation with other physical, oceanographical and seismic parameters in the site.
