Because of the state of the tides at Heysham, the outbound
journey on the Pace and the return leg on the Anglia began later
than usual at 11.30. This meant that only the first half of
the crossings would be available for survey, and although the whole
of the survey route was covered over the two days, the normal two
full days of recording was not possible.
After the usual very friendly welcome on board by the Seatruck crew and welcome to the bridge by our captain Colin, we left Heysham in good if somewhat misty conditions. There was the usual flurry of recording off Heysham power station where we saw a variety of gulls perched on the various breakwaters and buoys, and a flock of over 40 Knot roosting on the breakwater. We were passing over the Lune Deep when we had our first encounter with a Harbour Porpoise, which briefly showed a dorsal fin not far in front of the ship. It was from here that we had the first sightings of Little Gull, which were seen regularly for the rest of the recording period.
As we moved out south of the Barrow wind farms, we picked up the first Kittiwake, with increasing numbers of Guillemot, a small number of Razorbill and a solitary Puffin. The highlight of the outbound trip was a superb sighting of two Harbour Porpoise swimming very close together and showing several times as they passed to starboard of the ship.
As dusk approached all bird activity slackened off, and we left the bridge at 16.15 just as we passed the Calf of Man, spending the rest of the trip collating our sightings and eating a hearty supper with the other passengers.
For our return leg from Warrenpoint, this was the first time the crew of the Anglia Seaways had encountered a MARINElife survey team. They could not have been more helpful and accommodating, and after we had been given a second breakfast we were warmly welcomed on the bridge by Captain Orpheus Kekus as the ship began moving up Carlingford Lough towards the open sea.
There was much Cormorant and Shag activity along the lough, with a large roost on the exposed islands near the lighthouse, which left very little room for a small number of Grey Seal, although several of these had already been seen loafing in the waters of the lough. A skein of light-bellied Brent Geese flew past the ship, and singles of Black Guillemot in spectacular winter plumage and Great Crested Grebe were seen as we approached open water.
The western coastal waters of the Irish Sea are proving to be very productive for wildlife activity. On this trip we were rewarded with some reasonable views of Great Northern Diver not far out from Carlingford Lough, while we seemed to be endlessly noting down the good numbers of gulls and auks, with a small number of Great Skua also seen.
About two hours out from the coast, a large flock of mixed gulls and auks feeding on the sea ahead of the ship caught our attention, and as we were scanning to count these we were delighted with a brief but clear view of a Risso's Dolphin as its back and dorsal fin arched out of the water.
As we continued toward the Isle of Man, there were regular
sightings of Guillemot, Razorbill
and Kittiwake, with a couple of adult
Gannet also lazily flying by. A close view
of three Harbour Porpoise was our last cetacean
encounter, and bird numbers decreased as the dusk drew in. We left
the bridge at 16.30, with the lights of Castletown and Port St Mary
passing away to stern.
As the sole passengers on this crossing, we were treated very well by the crew and spent the evening as we approached Heysham chatting with some of them about Marinelife and the value of the survey. Our thanks as usual to all on the Seatruck Pace and Anglia Seaways, as well as the helpful staff at Heysham and Warrenpoint.
