Seven bottlenose dolphins, two Atlantic grey seals and three harbour porpoises

Ten minutes into the survey two bottlenose dolphins, an adult and juvenile, were spotted 60 metres off the starboard side of the boat travelling eastwards with a group of seabirds feeding nearby. After another forty minutes a female Atlantic grey seal was seen in the water 40 metres from the boat. Halfway into survey another pair of bottlenose dolphins, again an adult and a juvenile, were observed foraging in front of the boat. Shortly afterwards a group of three adult bottlenose dolphins were spotted foraging 100 metres behind the boat then an Atlantic grey seal was seen travelling southwards. Towards the end of the survey three harbour porpoises were observed near to the boat travelling south.

Weather conditions: sea state 0-2, visibility >10km, low swell
Forty three bottlenose dolphins, thirteen Atlantic grey seals and three harbour porpoises

Towards the beginning of the survey a large disparate group of bottlenose dolphins was spotted offshore travelling quickly westwards. A group of approximately 15, including a juvenile and a calf, were observed leaping, bow riding and tail slapping with other groups observed travelling and circling in the vicinity. A female Atlantic grey seal was also seen in front of the boat and another Atlantic grey seal was halfway into the survey. An hour into the survey a pair of dolphins was observed travelling west-southwest approximately a kilometre off the starboard side of the boat. Half an hour later two harbour porpoises were observed foraging behind the boat. Shortly afterwards two bottlenose dolphins, an adult and calf, were seen in the distance travelling southwest. This sighting was followed by an individual harbour porpoise travelling northwest and an Atlantic grey seal in the water closer to the boat. Five minutes later two groups of bottlenose dolphins were spotted. One group, 300 metres to the starboard side of the boat, was observed travelling north and the other, on the port side, was seen travelling southwest. Three hours into the survey an individual bottlenose dolphin was spotted leaping in the distance. A few minutes later a group of five bottlenose dolphins, including 1 juvenile and 1 new born, were seen travelling east in front of the boat and were observed foraging and leaping. After another fifty minutes a female Atlantic grey seal was spotted in the water 80m from the boat. A group of five bottlenose dolphins including one calf were seen 10 minutes later foraging followed by a mother and calf group five minutes later travelling fast which was seen at the same time as another group of 3 adult dolphins which were foraging. Then 10 minutes later a group of four seals were seen and this included two females in the water and two pups in a cave. Then over the course of the next ten minutes four more seals were seen near Cwmtydu, with three females in the water and one pup in a cave. Then in the last ten minutes of this survey two more dolphins were seen for a brief moment 1km from the boat.

2hr survey. Start time 12:45
Weather conditions: sea state 1-2, visibility >10km, light swell
Four harbour porpoises, two bottlenose dolphins and two Atlantic grey seals

About 40 minutes into this survey a group of four adult harbour porpoises were seen travelling west 200m from the boat and this was followed 15 minutes later by a mother and calf group of bottlenose dolphins foraging 150 m from the boat. The final sighting of this trip occurred half an hour later when two grey seals were sighted 50m from the boat, with one seen hauled out and another in the water.

2hr survey. Start time 14:45
Weather conditions: sea state 1, visibility >10km, light swell
Five bottlenose dolphins, three Atlantic grey seals and two harbour porpoises

About 45 minutes into this trip a group of five bottlenose dolphins including one calf and one new born were seen mingling at the surface and travelling SE 1km from the boat. Then 20 minutes later a female Atlantic grey seal was spotted in the water. Then ten minutes later another female was seen hauled out followed five minutes later by another seal seen in the water. The final sighting of this trip was seen 20 minutes later when a group of 2 harbour porpoises were seen travelling SSE whilst foraging.
