Comparison of multiparameter probes

This report focuses on two important parameters for biofouling image analysis: the artificial light and the distance to the structure. The first section presents the available tool that was already deployed in several studies in link with industrial needs (O’Byrne et al., 2018c) and the laboratory equipment. Section 2 focuses on the automatic segmentation algorithm and the indicators of quality of assessments. Finally section 3 introduces configurations that were tested and the key results.

Monitoring data on biomass (fresh weight in air and water), biovolume, thickness.

Measurement of the diameter of the biocolonised moorings and the composition of the biofouling at T+12 months of immersion.

Database of images collected at ABIOP monitoring sites (UTLN = Mola buoy offshore Banyuls, SEMREV = special marks east and north, UN = biocolmar buoy) + report on biofouling characterisation (rapport_taxo_ABIOP_provisoire)

Measurement of the diameter of biocolonised moorings and biofouling composition at T+6 months of immersion.
