* NDIR-based pCO<sub>2</sub> sensors with planar membrane equilibration (KM CONTROS HydroC pCO<sub>2</sub> sensor) cannot easily and without major compromises be integrated into platforms such as floats and glider which have tight power and hydrodynamic limitations. For these platforms, currently no fully satisfactory pCO<sub>2</sub> sensor exists and we have to wait for the pCO<sub>2</sub> optode technology to further develop and mature.

Figure 1: Mixed layer diel cycles of pCO<sub>2</sub> (left) and O2 (right) observed with a Lagrangian surface-tethered drifter with biogeochemical sensor package (S, T, pCO<sub>2</sub>, O2, nitrate, chlorophyll) in the southern Indian Ocean during R/V SONNE Cruise 234/2 (July 2014). The pCO<sub>2</sub> data show a precision of <0.3 µatm which allows to resolve diel cycles of less than 2 µatm.</div>

Figure 2: Results from two test deployments of the moored submersible winch system with biogeochemical profiler (T, S, O2, pCO<sub>2</sub>, chlorophyll) in the Koster Fjord near the Sven Lovén Centre for Marine Infrastructure in Tjärnö/Sweden in Sept. 2014. The instrument was set to frequent profiling from 140 m/100 m to just below the surface. A trial deployment at the Cape Verde Ocean Observatory in the tropical Atlantic (17.6°N, 24.3°W) in September 2015 was not successful. The next deployment of a mechanically improved system is planned for Jan. 2017 in Cape Verdean water.</div>

Figure 3: Results of a successful deployment of the Liquid Robotics Wave Glider with biogeochemical sensor package (T, S, O2, pCO<sub>2</sub>, gas tension, chlorophyll) in the open ocean around the Cape Verde archipelago off West Africa in May/June 2015. The Wave Glider was deployed near the island of Santo Antão and programmed to sail to the Cape Verde Ocean Observatory (17.6°N, 24.3°W) where it performed repeated short meridional sections.</div>
