21/07/2015: 29 bottlenose dolphins.
2hr survey. Start time 9:00.
Weather conditions: Fair, sea state 1-2, wind direction S/SW.
Three bottlenose dolphins.
Three bottlenose dolphins were observed taking long dives, possibly foraging at depth, north of the harbour wall at the beginning of the survey period. The dolphins stayed in the area, occasionally venturing closer to the harbour wall, throughout the first half of the survey period. At the beginning of the second half of the survey period the dolphins travelled out of the area towards the headland, before disappearing for the rest of the survey period.
2hr survey. Start time 11:00.
Weather conditions: Fair > overcast > rain, sea state 1-2, wind direction S/SW.
2hr survey. Start time 13:00.
Weather conditions: Overcast, sea state 2, wind direction N/NW/W/SW.
Six bottlenose dolphins.
Six bottlenose dolphins were observed entering the survey area, from beyond the headland, in two groups at the end of the survey period. They travelled south-west, past the harbour wall, with regular surfacing and some rapid travelling with forward leaps. The groups split up further across the survey area and were observed leaping and breaching, with some foraging behaviour also seen.
2hr survey. Start time 15:00.
Weather conditions: Overcast, sea state 2-3, wind direction SW.
Twenty bottlenose dolphins.
The six bottlenose dolphins seen in the 13:00 survey period were observed at the beginning of the survey period taking long dives, thought to be foraging at depth, across the survey area. Two more bottlenose dolphins were also seen, totalling eight dolphins altogether in the first fifteen minutes of the survey period. A further twelve bottlenose dolphins were seen in the survey area across the rest of the survey period, displaying various behaviours such as milling around at the surface, long dives (thought to be foraging at depth), and leaps/tail slaps/lunges. Two of the dolphins towards the end of the survey period were also observed bumping into one another.
