2/11/2017: Bottlenose dolphins and Atlantic grey seals

2hr survey. Start time 09:00
Weather conditions: Overcast, sea state 1, wind direction SW/W

This survey started with one group of five bottlenose dolphins (including 2 calves) showing fast circling and mingling behaviour halfway between New Quay head and the cardinal marker during the first interval. Nothing else was seen until the start of the second hour, when an adult and a calf were seen travelling east whilst forging between the headland and the cardinal marker for half an hour. They disappeared for one interval, then reappeared in the last 15 minutes travelling back towards the headland again whilst foraging.

2hr survey. Start time 11:00
Weather conditions: Overcast/rain, sea state 1/2, wind direction NW

One bottlenose dolphin was seen foraging near the headland after 15 minutes into the survey. This individual was then joined by an adult and a calf who were seen foraging between the headland and the cardinal marker for 45 minutes. This group then disappeared for half an hour and was seen again foraging halfway between the headland and the cardinal marker in the last 15 minutes.

2hr survey. Start time 13:00
Weather conditions: Overcast, sea state 2/1, wind direction NW

A group of two adult and one calf bottlenose dolphins were seen chasing prey and travelling from the headland to the cardinal marker during the first 15 minutes, and then foraging just beyond the cardinal marker. Nothing was then seen for 15 minutes until 2 bottlenose dolphins were seen foraging whilst travelling north-west past the headland and out of the survey area. During the second half of the survey, just one female Atlantic grey seal was seen bottling about 300m in front of the harbour wall.

2hr survey. Start time 15:00
Weather conditions: Overcast, sea state 1/2, wind direction S/N

Nothing was seen during the first half hour of this survey, until a group of three bottlenose dolphins travelled east from the headland. This group then displayed slow mingling behaviour just west of the cardinal marker while another group of three adults and two calves travelled around the headland towards the harbour wall. A third group was also seen during this interval: four adults and a calf showed slow mingling behaviour approximately 1 kilometre in front of the harbour wall.
At the start of the second half of the survey, a group of ten dolphins (including 3 calves) were seen travelling west away from the cardinal marker, while a group of three adults and one calf were seen halfway between the cardinal marker and the headland, foraging whilst travelling north-west. During this interval a female Atlantic grey seal was seen bottling in front of the harbour wall.
A group of three dolphins (including one calf) were then seen foraging and travelling north from just west of the cardinal marker, whilst an adult and calf pair also travelled north, starting from about 100m north of the cardinal marker. Meanwhile, a group of three adults and two calves displayed slow mingling behaviour near the cardinal marker. This group of five then split up and two adults remained foraging over the reef while the rest foraged closer to the harbour wall. Meanwhile, a group of three adults and one calf displayed slow mingling behaviour approximately 1km in front of the harbour wall. In the last 15 minutes, a female Atlantic grey seal was seen bottling just off Dolau beach, an individual dolphin foraged between the harbour wall and cardinal marker, and the group of four dolphins seen previously continued to forage about a kilometre off of the wall.
