The impact of Marine Renewable Energy (MRE) production on pelagic organisms is badly known. Pelagic organisms are key ecosystem components, as they produce, by photosynthesis, and funnel the energy and biomass to upper trophic levels and other marine ecosystem components.
The EchoSonde project aims at developing an integrated, cost-effective, cabled seabed observatory to monitor the impact of MRE on coastal pelagic ecosystem, near the future Saint Nazaire’s windmill farm. The EchoSonde observatory features an innovative broadband echosounder to characterise at very high resolution the distribution, nature and size of pelagic organisms.
The postdoctoral fellow will develop methodologies for near-real time analysis of the EchoSonde observatory big data flow. This should provide new insights on the pelagic ecosystem dynamics in the vicinity of the Saint Nazaire offshore wind farm, from diel to seasonal scales. Acoustic and hydrobiological data collected during sea surveys will be compared to EchoSonde outputs, to punctually validate the continuous, hydro-acoustic characterisation of the pelagic ecosystem provided by the observatory.
