Keywords: Abstract: The continuous monitoring of radioactivity in the oceans is crucial to identify potential incidences due to accident or blasts as well as due to various phenomena that may take place due to climate change and natural hazards. Effective monitoring provided in a continuous basis the type of the radioactive contaminant as well as the activity concentration of radionuclides in different matrices in the ocean environment. The spatial and temporal monitoring is performed using in-situ methods combined with low consumption detection systems that are enough tolerant for ocean conditions; while the data transmission is performed using wireless or on line methods. In the frame of RADCONNECT project; the integration of a medium resolution underwater radioactivity system was integrated in an existing cabled ocean observatory placed in Helgoland Island. The system operated in an online mode controlled by the operational Centre (AWI) as well as from the end-user (HCMR). The system provided gamma-ray spectra and activity concentration of key radionuclides that were enriched in the sediment as well as in the seawater during the monitoring period. The data analysis proved that the system had a stable operation in terms of voltage stability so that all acquired spectra could be integrated effectively in time to produce high statistically gamma-ray spectra for further analysis.
