Notes.
Data include: trip duration, time at sea, dive depth, maximum depth, dive duration, total number of complete trips (Trips) and recorded dives (Dives), percentage of dives using shallow benthic (SB), deep benthic (DB), epipelagic (EP) or mesopelagic (MP) dive types, total number of potential prey captures per individual (PPC) and rate of PPC per dive (PPC rate).
P
Only partial dive log and accelerometer data available for trips.
*
There was no spatial data available such that it was not possible to allocate dive to specific foraging trip.
