To produce science of excellence is essential to have well calibrated and tested sensors that allow to acquire excellent data. Thus, marine sensors need to be tested in real and controlled environments in order to assure, both, proper functionality of the sensor and good enough measurements. Most of times is not enough testing on the lab. Field tests and an inter-comparison with similar sensors can help instruments manufactures, platform operators and scientist to validate instruments.
OBSEA (Expandable Seafloor Observatory) offers the possibility to deploy different types of measurement instruments, communication modules or scientific experiments, and allow real-time communication with the deployed devices. Devices can be deployed at 20m depth or at the surface buoy.
