Date = Date of dolphin observation written as dd/mm/yyyy observation_id = Group number. If not duplicated then group size of 1, if duplicated group size is represented by the number of repeats (e.g., observation_id 2 is repeated twice meaning the group size is 2) ID = anonymized dolphin ID gps_south = GPS coordinates (latitutde) gps_east = GPS coordinates (longitude) sex = MALE/FEMALE for each dolphin assigned to each row Habitat = Habitat classification where the observation occurred (Deep open, Channel, Shallows) Forage = YES/NO whether the dolphin was foraging during the observation Dataset: RC_Availability.csv This file contains data for the time points each dolphin was alive during the study ID = anonymized dolphin ID (this matches the RC_Data.csv file) entry = point of entry into the study depart = point of exit out of the study
