The oceans play a key role in climate regulation with the climate change being the most important environmental issue that human societies have to face. To dramatically increase our observing capacities, we need to develop and deploy autonomous, multi-disciplinary oceanic observatories for a long-term monitoring of the environment. In-situ autonomous biogeochemical sensing in marine environment is an immense challenge. The environment is harsh, dark, difficult to access, subject to biofouling, and characterized by large pressure, temperature and ionic strength variations… Nevertheless, the seawater long-term monitoring requires an in-situ miniaturized autonomous instrumentation able to achieve excellent figures of merit: lifetime, stability, high precision, fast response time, good reproducibility, robustness, resistance to biofouling, and low energy consumption.
