2hr survey. Start time 09:00

Weather conditions: low visibility (fog), sea state 1, wind direction N/NW

No sightings.

2hr survey. Start time 11:00
Weather conditions: low visibility (fog) at first and then sunny, sea state 1, wind direction NE
Seven bottlenose dolphins and one Atlantic grey seal

Heavy fog inhibited visibility of the bay for the first half an hour of the survey, before clearing quickly. As soon as the fog cleared, a group of four bottlenose dolphins was spotted travelling past the headland in an easterly direction. As they travelled, a further two shortly joined them and a few of the dolphins were seen to leap and tail slap as they moved along. The group was seen to travel with slow but steady progress towards the cardinal marker for the majority of the survey, before being observed foraging with long dives in the last half an hour. A lone bottlenose dolphin was also sighted travelling in a westerly direction towards the headland. In the last fifteen minutes of the survey period, five bottlenose dolphins were seen to still be around the cardinal marker, leaping, breaching and tail-slapping. The lone dolphin was observed changing direction and heading back across the bay in an easterly direction.

2hr survey. Start time 13:00
Weather conditions: sunny, sea state 0, wind direction SW
Six bottlenose dolphins

The six bottlenose dolphins seen at the end of the previous survey were still seen in the survey area at the beginning of the survey period. Four dolphins were seen behind the cardinal marker, foraging with long dives. A lone dolphin was seen to be foraging further in and to the left of the cardinal marker and another travelling east across the bay with irregular surfacing. The six dolphins were seen to surround the cardinal marker, all foraging with long dives, throughout the majority of the survey, with some displaying splashy behaviour at the surface. In the last half an hour of the survey period, three dolphins were still seen to be foraging near the cardinal marker and another lone dolphin seen travelling east across the bay near the headland. At the end of the survey period, two dolphins were seen to still be foraging near the cardinal marker.

Weather conditions: fair, sea state 0, wind direction NE
Seven bottlenose dolphins

Four bottlenose dolphins were seen at the beginning of the survey period, far out and travelling in a westerly direction. The group remained in the area, displaying behaviours such as splashy surface activity and foraging, for the first half of the survey. During the second half of the survey period, the group had been joined by other individuals, forming a group of five and a lone individual that were seen to travel across the bay in a easterly direction. Throughout the second half of the survey period, the group of five were seen to move across the bay, with the lone individual observed travelling past the cardinal marker with another lone bottlenose dolphin. In the last half an hour of the survey, eight bottlenose dolphins were observed in the survey area around the cardinal marker, foraging and displaying splashy surface activity.

2hr survey. Start time 17:00
Weather conditions: fair, sea state 1, wind direction N/NW
Six bottlenose dolphins

Four bottlenose dolphins remained in the survey area from the previous survey period, with a pair displaying splashy surface behaviours near the west side of the cardinal marker, a lone individual travelling across the bay in an easterly direction with irregular surfacing, and a lone individual foraging with long dives on the other side of the cardinal marker. Throughout the rest of the survey period, a total of six bottlenose dolphins were seen foraging with long dives and displaying splashy surface behaviour around the cardinal marker. At the end of the survey, fog was seen to be rolling back in over the bay.
