This suggests a general response in which elephant seals perform, on average, shorter, steeper dives during periods of successful foraging - aligning with predictions from the marginal value theorem (MVT), that a forager stays in a patch only until gains drop below the neighbourhood mean. (3/4)

We found that as foraging success increased, seals increased transit (ascent, descent) rates and decreased relative dive durations for a given depth, with no response in surface recovery. And, importantly, this was consistent irrespective of sex and foraging habitat... (2/4)
