|Biology and fisheries|
|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.
|Moorings, landers, buoys|
|Water bottle stations||53° 46' 50" N 5° 38' 2" W — A recovery of the instrument mooring and servicing. The thermistor chain and water samplers were removed and the data downloaded. Then they were reattatched and the buoy redeployed.|
|Subsurface temperature measurements||53° 46' 50" N 5° 38' 2" W — A recovery of the instrument mooring and servicing. The thermistor chain and water samplers were removed and the data downloaded. Then they were reattatched and the buoy redeployed.|
