The macrofouling qualification and quantification protocols were extracted from 64 public documents (33 scientific articles, 1 book chapter, 22 internal reports, 4 internship reports and 4 theses) presenting studies conducted in France (n = 40), Europe (n = 16) and the world (n = 8).

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

Review to identify the state of knowledge on anodes and their environmental impact. Report serving as a basis for further work (deliverables 3 and 4)

Excel database containing the information collected for the atlas (45 sources for the French maritime façades + 24 on a global scale) and shapefiles for the cartographic representation of the available data

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

Configuration of the ocean model and biogeochemical modules

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.

During the ABIOP project launch meeting, the consortium agreed to add a task to the project aimed at identifying the challenges of biocolonisation in an ORE context. This additional work is indeed necessary because it allows the organisation, updating and presentation of the reflections undertaken by biofouling experts from various industrial and research entities and federated by FEM, for several years on this topic.

Report on the assessment of the chemical risk of aluminum-based galvanic anodes on the environment

Proposal of protocols for measuring several biofouling variables (fresh weight in air, fresh weight in water, biovolume, thickness) that were tested during the project.
