Ocean processes are of biological, geological, chemical or physical nature, occurring at micro - to kilometer scales, from less than seconds to centuries, turning the understanding and the sustainable management of the ocean into a multi-scale and multi-disciplinary effort. To address this variability with a cost-effective solution, the European FP7 project NeXOS has developed a new generation of multifunctional, compact, interoperable and Web enabled optical and acoustical sensor systems as well as sensors for fisheries management. These sensor systems have been designed, built, tested and validated in a number of platforms using scenarios that are demonstrations of applications for long-term implementation. The performance validations have been carried out during 2017 and the most updated results are provided in this paper.
