Stephen and I arrived at the Southampton Docks car park mid-morning and walked to berth 105 to board the MS Neptune Aegli car carrier.  The vessel was still loading but sailed for Portbury on schedule just after midday.

We did a few hours surveying before dark at 5.15 and left the bridge shortly after we passed Weymouth.  The following morning, we began surveying just north of Lynmouth on the Devon coast well on the way into Portbury.  As we approached the lock gates to the inner harbour we could see large numbers of Shelduck feeding on the mud flats and one Oystercatcher.  We moored just before midday.

We had a few hours ashore at Portbury and after visiting the Seaman's Centre we explored the wildlife corridor which connects the shore with the hinterland between the car parking areas.  There is some reedbeds and the remnants of some lagoons.  Teal, Long-tailed Tit, Bullfinch, a solitary Goldfinch were spotted amongst the blackthorn hedge, willow and birch scrub.

The next morning crossing to Rosslare we had several sightings of Common Dolphin (19 animals), one Grey Seal and a Red-throated Diver. The coastal habitat around the port looked promising and easy to access but unfortunately there was no time to explore it.    On the way out, we spotted one one Harbour Porpoise and had more sightings of Common Dolphin (77 animals) as they raced in to ride the ship's bow wave.

Sunday morning found us west of St. Nazaire with the calmest weather we had had but there was still a swell of more than 2 metres.  We had regular sightings of Gannet and Kittiwake and our first Common Dolphin sighting at 9.15 a.m. when we were in 150 m. depth.  We were watching the depth  contours hoping for some larger cetaceans as we neared the abyssal plain. We reached 4000 m depth at 14.45.  An hour later a small pod of unidentified dolphins (ca. 20) were seen about half a kilometre off the starboard beam heading purposefully north, presumably on a hunt.

We arrived at Santander early the next morning.  We ventured out into a very cold Spain with snow on the Asturian mountains.  We had to be back on the ship for 11am and  there wasn't time to access the area outside the dock.  Birds spotted were Meadow Pipit and Pied Wagtail, everything else possibly being scared off by the port's recording of gull alarm calls keep them off the new cars.

We left Santander early and headed for a wild-looking sea beyond the harbour.  Large breakers coming in on the rock where we had been expecting to see Shag and Cormorant gathered.  Yellow-legged Gull, Guillemot, Cormorant were seen on the way out.

The weather looked threatening with grey cloud, a 4/5 m. swell and a sea state of 8.  It got a bit brighter but remained rough for the rest of the day.

By 14:30 we were into deeper waters (1000m.), dropped off the Santander canyon and were at  3000m by  15:15.  Stephen spotted a Cuvier's Beaked Whale masquerading as a log.  In fact, there were 2 and one of them blew just as they passed quite close to the starboard side.  We were hopeful of seeing a lot more in what would be our last opportunity on the deeper waters but the spotting conditions were not favourable. We did have one more Common Dolphin sighting close in before the end of the day.

The next morning we went to  the bridge just before entering the Traffic Separation zone off the Iles d'Ouessant.  Wind speeds were 8/9 most of the time (gusting to 50 knots, but we stayed on the bridge to survey the birds at least.   This was the first time we saw any fishing boats for the whole trip.  We had steady numbers of Great Skua, Gannet, Kittiwake and larger gulls, some of them following the boats.  Just north of Roscoff, 2 Common Dolphin came in to bow-ride.

We arrived overnight in Le Havre and after several rough nights, we had a reasonable night's sleep.  After going thought the harbour lock the following morning we finally left the Le Havre breakwater at 3.15 pm.  The wind speed quickly got up to Bf.7 again and by 5 pm. the light was too poor to survey.

Our thanks to Captain Georgios Xylouris, the crew and to the cook, Oleg Krasovskyi for keeping us fed and watered throughout the trip.
