Table 1.
Controlled exposure experiments (CEEs) conducted for both short-beaked (top) and long-beaked (bottom) common dolphins. For each CEE, the total estimated group size (minimum-best-maximum estimates from shore-based visual observers) and unoccupied aerial system (UAS) focal (sub)group size are provided. Each CEE type, date/time and range (in km) from the source to the centre of the focal group (UAS location) is specified. Focal group modelled received levels (RL) in maximum root-mean-square (RMS) sound pressure level (SPL; dB re: 1 μPa) for any ping are provided for all MFAS CEEs, as well as cumulative sound exposure level (cSEL; dB re: 1 μPa2 s) across all pings. The availability of sufficient data (Yes (Y) or No (N)) of each categorical sampling type (UAS, passive acoustic monitoring (PAM), visual monitoring for subgroups) to conduct response analyses within each CEE is stated.
