R&D into operational methods for tidal race

Jon Buoy is a bespoke real time monitoring buoy for tidal races Jon Buoy

This area for large pictures/charts/tables,etc with one line captioning.

Unique design prevents submersion

Wi-fi provides real-time transmission of large data sets

Linked to vessels to support marine operations

Jon buoy is equipped to monitor tidal flow, but it also has the opportunity to monitor other environmental variables in real time. Knowledge gap

Mojo Maritime are actively involved in R&D and have ambitions to develop the ‘Jon Buoy’. The following knowledge gaps were identified for this internship:

• Wave sensor setup, and data processing

• Validation of measured results, and Quality Control algorithms

• Oceanographic measurements for environmental assessments Work done

Co-ordinated field work for wave and measurement Reviewed acoustic monitoring and sediment tracking using existing systems Informed the re-design of Jon buoy systems to introduce a modular system Developed algorithms for the measurement of waves Contribution to career

Relationship with Mojo and Meygen. Research knowledge transfer opportunity for oceanographic monitoring and analysis Addressing uncertainties would support continued investment in marine renewables A valuable experience, where I learnt about the commercial sector, and developed a closer understanding of the role of research in supporting industrial development
