| Summary of measurements |
- -Deployment of the DySPI structure to acquire video images of seabeds with Haploops (9 in all).
-Poor weather conditions throughout the cruise limited the duration of deployments and caused the acquired videos to be of little use, seeing their poor quality (too much turbidity).
-Water samples taken in NISKIN bottle during a tidal cycle to measure suspended matter and Chlorophyll + CTD profile.
-Samples were taken with Van Veen grab to characterize the seabed and verify the density and quality of Haploops.
