| Physical oceanography | |
| Water bottle stations | 53° 46' 53" N 5° 38' 0" W — Guard buoy and anchor recovered, serviced and redeployed. |
| Water bottle stations | 53° 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. |
| Biology and fisheries | |
| Phytoplankton pigs (eg chlorophyll, fluorescence) | 53° 43' 26" N 6° 4' 2" W — Guard buoy and instrument package were recovered. The instrument package was removed and the guard buoy redeployed. |
