Physical oceanography 
Water bottle stations53° 46' 53" N  5° 38' 0" W — The instrument mooring was recovered. The biological water sampler was removed and the nutrient water sampler was replaced by a different model. Information was downloaded from the model, sensors were reprogrammed and reattatched before the mooring was redeployed.
Water bottle stations53° 46' 53" N  5° 38' 0" W — Guard buoy and anchor recovered, serviced and redeployed.
