18 Bottlenose Dolphins

Right from the beginning of this survey six individuals were seen, of which three were milling around at the surface north of the wall, two were doing long dives and one individuals travelled north-westerly close to the harbour wall. While the lone one disappeared the other two groups joined, and another individual showed up close to the wall while another two were doing long dives near the cardinal buoy. Approximately halfway through the survey another lone individual showed up which also left the area soon. Then a new pair came into the area from the fish factory and left soon again, while the group of five was still north of the wall leaping, and the two near the cardinal buoy were still doing long dives. Then the group of five split up, three of them left the area while the other two moved towards the cardinal buoy. Almost at the same time another six individuals entered the area, first milling at the surface and then travelling eastwards from the fish factory.

Twelve bottlenose dolphins

At the beginning of this survey still the two individuals of the previous survey were around, and another four individual showed up leaping north of the wall. While the group of two disappeared the group of four stayed around, and another individual was seen travelling north-easterly close to the wall before disappearing from view, and afterwards the other four disappeared as well. Then for half an hour only one new individual was seen doing long dives north of the wall, suspected to be foraging at depth. Just when this individual travelled past the fish factory four individuals were coming in from that area, being very active including leaps.

Eight bottlenose dolphins

At the beginning of this survey one individual was seen milling at the surface near the fish factory. After half an hour a group of two individuals were seen milling in the same area, and a group of six individuals was leaping in the same area as well. Soon these two groups left and it was again just the one individual north of the wall, which disappeared halfway through the survey. At the end of the survey two individuals were seen leaping near the fish factory.

Two bottlenose dolphins

During this survey two individuals, including a juvenile, were seen throughout almost the entire two hours. They were mostly seen doing long dives, suspected to be foraging at depth, near the cardinal buoy, but also travelled more westwards and back. At last they were leaping again near the cardinal buoy, and then they disappeared before the end of the survey.

Weather conditions: sunny, sea state 1-2-1, wind direction N
Four bottlenose dolphins

Halfway throughout this survey three individuals were seen milling at the surface near the cardinal buoy. Then another individual was seen leaping north of the harbour wall and one of the individuals of the group of three travelled westwards to a location north of the wall. At the end both of these lone individuals were separately travelling eastwards in an irregular interval.

2hr survey: start time 17:00

Seven bottlenose dolphins

At the beginning still the two individuals near the cardinal buoy were doing long dives, where after they travelled westwards. In the meantime one individual appeared from past the fish factory, first doing long dives and afterwards milling around at the surface near the fish factory, before disappearing again. The two individuals who split up earlier joined each other again and were milling around at the surface north of the wall, while at the same time two other individuals were seen far out north of the cardinal buoy for a short moment. Then a mother and calf came travelling in from the fish factory into the harbour, but left quiet quickly after some milling around at the surface due to disturbance. They went north of the wall while the other two individuals were still milling around at the surface north of the wall.
