The animals were spotted and the boat started to get closer

 

Geographic & Weather parameters such as GPS coordinates, sea and wind states were taken

 

The behavioural state was noted (Travel, Hunting, Milling, Resting, and Socialising)

 

The animals get close to the boat (less than 30 meters)

 

15 minutes video is recorded trying to include all the behaviours performed by the animals

 

All the behaviour frequencies are noted and put on an excel sheet

 

The data are statistically analysed
