DEVOTES has published the first report on the application of non- invasive biosensor, one of the Innovative Monitoring Techniques proposed within the WP5

This report summarise the application of high frequency, non-invasive biosensors (HFNI) to measure biological rhythms and shell growth in bivalves using real time data transfer and analysis.

In particular, the “Report on the application of  non- invasive biosensor” documents the method, its applications and the results achieved from so far after 2.5 years of deployment at one of the three locations in  the Barents Sea.

The ultimate aim of this activity within DEVOTES is to determine the potential utility of the method for long-term water quality monitoring, in the context of the Marine strategy Framework Directive (MSFD).

Scientists working in WP5 have identified a number of potential uses of the high frequency, non-invasive biosensors for monitoring and early-warning alerts of changes in water quality, such as temperature, releases of contaminants to toxic algal blooms.

Potential relevant applications for the MSFD include their use in bathing beaches and large harbours, petroleum installations and aquaculture sites.


This study will continue for the next two years. Stay tuned for learning  more about the Innovative Monitoring Tools!
