Objective	PHRESQUES scientific cruises are supported by the CPIER PHRESQUES research project (2017-2019). The objectives of the cruises are: Maintenance of the coastal buoys SMILE and SCENES. Calibration of all sensors deployed from the scientific buoys, and evaluating uncertainties associated to long term monitoring. Identifying evaluating and understanding SPM dynamics regarding natural forcing : tides, seasonal blooms (i.e. variability of the organic matter content).
