Carbon dioxide (CO2) and methane (CH4) concentrations in the oceans are key parameters for addressing many scientific questions as well as industrial applications. Extensive greenhouse gas datasets are important for reliable climate modeling. “Point measurements” help to understand the underlying processes or form the basis for countermeasures. Ocean acidification, natural gas seepage, carbon capture and storage (CCS) as well as pipeline monitoring are only some examples for fields of applications. The need for extended in situ measurements of dissolved CO2 or CH4 can only be met by having the right instrumentation combined with and efficiently integrated into modern platforms. Therefore the sensors need to be small, reliable and intelligent. The demands on sensors and platforms recently follow the same trend of becoming more and more autonomous. Thus it is very important to emphasize the point of sensor integration into platforms at an early stage in order to achieve an intelligent combination of the measuring device and its carrier. The concrete orientation of sensor improvements and developments to the platform manufacturer’s as well as scientific and industrial end-user’s needs leads to an effective, applied and hence successful integration.
