I boarded Neptune Aegli at 22.00 and introduced myself to Captain Georgios Xylouris before being shown to my cabin. The ship sailed at 02.00.

After a large breakfast, I headed up to the bridge at daybreak to find that we were off Brixham. The sea state was good and with the light behind us I had great viewing conditions. Groups of Common Dolphin were seen and then four groups of Pilot Whale. A very close Minke Whale ended a busy session.

A group of Herring Gull were mobbing something and as they came nearer and nearer, an unfortunate Barn Owl revealed itself out at sea and in full sunshine. At 16.00 we turned the corner around Lands End and and I watched the green flash as the sunset at 18.30 before heading down for dinner.

Most of Sunday was spent in Portbury, we set sail at 16.00 bound for Santander as Rosslare was not being visited on this trip. I managed a couple of uneventful hours before darkness fell as we sailed between Steepholm and Flatholm.

Overnight the wind increased to between 20 and 30 knots and a large swell was running. Morning saw us 30 miles off the Brittany coast near the island of Ouessant.  As the sun rose, I was greeted with low glare. As we approached the northern shelf, good numbers of dolphins were seen including a nice tight packed group of Striped Dolphin. A spectacular sight in this area was nearly 300 Great Shearwater flying close to the bow in a fifteen minute period.

The following morning we berthed in Santander. As it was low tide I headed to the estuary directly across from the dock. A raised platform gave good views of waders and ducks with the highlight being 10 feeding Spoonbill. After previously being fooled by the raptor scarer on a lamp standard, I was amused to see a real-life Peregrine sat on a standard next to the scarer!

We departed at 12.30 for the 22 hour sailing to Le Havre. A second owl of the survey was seen as we headed into the Southern Bay in the form of a Short-eared Owl. A flock of 12 Skylark flew towards the coast. The wind soon increased and viewing was very difficult, no cetaceans were seen on this section of the survey.

The sea calmed overnight and Wednesday I arrived on the bridge to see better viewing conditions. Just 30 miles west of Alderney before we entered the Channel shipping lane many small groups of Common Dolphin were seen but sea bird numbers were quite low.

Thursday was spent in Le Havre where a Black Redstart spent the day on the rocks close to the ship. 300 Coot were feeding in the estuary and I observed feeding frenzies of gulls and Cormorant. A short amount of time to survey after leaving port produced a Harbour Porpoise. I headed down for yet another large meal, thanked the crew and Captain for all their assistance and had a few hours sleep before disembarking in Southampton early Friday morning.
