Presently, there is no fast and easy to use sensor available which is capable of measuring high resolution depth profiles of dissolved nitrous oxide (N2O) in the water column. Therefore, a trustworthy and time-efficient sensor to measure dissolved N2O in seawater at high resolution is proposed. This sensor will be built upon novel infrared technology (IR) for gas detection using a field-deployable near IR light source, a sensitive photovoltaic detector, a multipass gas absorption cell, and a gas membrane technique for gas separation.
