Summary of measurements

-CTD profiles (117): characterization of South Senegal upwelling plume's functioning.
-ADCP moorings and thermistor chain on continental shelf: characterization of South Senegal upwelling plume's functioning.
-Water samples taken to analyze O2, pigments, nutrients, salinity, ammonia and taxonomy: characterization of upwelling plume's functioning.
-LIDAR atmospheric measurements (10 days): small and medium-scale ocean-atmosphere feedbacks.
-SCANFISH legs (towed undulating CTD and fluorimeter approx.30 hours): characterization of South Senegal upwelling plume's functioning.
-Deployment of an ARVOR profiling float: characteristics of water body off the the South Senegal shelf.
-Deployment of drifting surface buoys (4): circulation on edge of continental shelf.
-Collecting dust/aerosols (2 filters daily during the 10 days of the cruise): enrichment of the South Senegal zone by Saharan dust.
-Radiance measurements using SIMBADA (17): assessment/improvement of satellite ocean colour measurements in the zone.
-Routine shipboard ADCP, multi-frequency echosounder, TSG, meteorological parameters (Batos): understanding South Senegal upwelling plume's functioning.
