Phytoplankton pigs (eg chlorophyll, fluorescence)Quantity: number of samples = 5
Description: At F3, F5, F1, F4 and F2 the water sampler was deployed to obtain standard samples and to obtain calibration data for the fluorometer
Phytoplankton pigs (eg chlorophyll, fluorescence)Quantity: number of samples = 2
Description: Rosette water sampler was deployed to acquire pre drawn water samples. Then later to obtain nutrient, chlorophyll and organic content from the depth profile.
