We arrived at Heysham port and transferred to the Clipper pace shortly after midnight and then soon in our cabins, prior to a dawn start at 5am.

Rissos Dolphin Adrian Shephard 07When we joined the bridge it was clear that the forecast conditions had materialised and were not far short of ideal for surveying with good visibility and little wind.  We gradually added a number of regular seabird species to the survey list as well as a small flock of Common Scoter which were notable in July and presumably returned early from their arctic breeding grounds.

A couple of cetacean sightings kept the spirits high, with Harbour Porpoise and Common Dolphin both being seen briefly.  Excitement then mounted when four large dorsal fins were seen ahead of the boat at about 300 metres range.  The shape of the fins and the relatively sedate activity led SD to suggest they were Risso's Dolphin and to our delight this proved to be the case.  

One animal was seen particularly well as we approached, with the white scarred skin characteristic of this species seen really well.  Although these dolphins occurs off Bardsey Island and there are fairly frequent reports from the Isle of Man, they are very rarely recorded on the Irish Sea survey routes so to have such good views was a real privilege.  

With the calm conditions continuing a couple more Common Dolphin and Harbour Porpoise records were added.  In terms of birds, larger numbers of Manx Shearwater began to be recorded as well as scarcer species with an Arctic Skua and then a Great Skua, though these proved to be the only ones of the trip.

Minke Peter Howlett 03We docked in Dublin around 11 am and took the chance to get some rest.  We began the return journey around 3 pm, giving at least six hours of daylight to hopefully add to what was already a good set of sightings.  A couple of Puffin were noted and small groups of Common Dolphin and Harbour Porpoise added to an already pleasing cetacean haul.  

As we left the Irish coast behind Nik saw a Minke Whale surfacing close in front of the boat going north.  Stephen dashed across the bridge and also saw it surface close to the boat heading east.  Minke Whale is rare on surveys in the Irish Sea so this was the icing on the cake for a great trip.

Thanks to Captain Steve Olbison and crew for their help and courtesy, and Seatruck staff at Heysham for a smooth transfer.
