2hr survey. Start time 11:00.
Weather conditions: fair/overcast/sunny, sea state 4-2, wind direction SW.
Six bottlenose dolphins, two harbour porpoises and one Atlantic grey seal.

During the second half of this survey the entire big three was observed. At first two harbour porpoises, including a calf, were traveling north of the wall quite close by. Then later one Atlantic grey seal was seen close to the head of the wall, and four bottlenose dolphins showed up, later followed by another two individuals. Two groups of two individuals were milling around at the surface north of the wall and doing long dives, while another one was milling around at the surface close to the head of the wall, and the sixth individual was also in the harbour, doing long dives.

Seven bottlenose dolphins and one Atlantic grey seal

At the beginning of this survey the female Atlantic grey seal was swimming in a northerly direction north of the wall. The two groups of two moved to positions in-between the head of the wall and the cardinal buoy, while the other two individuals stayed at the same place. A new individual showed up behind the cardinal buoy, which was later joined by another one from the previous seen individuals. During the survey the seven individuals kept splitting up and forming new groups whereby they were mostly doing long dives, suspected to be foraging at depth.

13 bottlenose dolphins

At the beginning of this survey five individuals of the previous survey were spotted, later joined by another one. They were mostly doing long dives, suspected to be foraging at depth. During the beginning of this survey they also kept reforming the groups, before they left the area halfway through the survey. In the last half an hour new groups came into the area, in total five individuals were spotted. At the end two of them were doing long dives near the cardinal buoy, two other individuals were milling around at the surface in between the head of the wall and the cardinal buoy, and the fifth individual was doing long dives east of the wall.
