Associations of acoustic backscattering with dive type, depth, and longitude. a Mean volume backscattering strength (dB) calculated over the duration of each dive for seal #2 to a range of 2 m, plotted relative to dive type: travel, drift, benthic, and just those benthic dives that occurred along the northern side of Monterey Canyon as the animal adopted a more tortuous track potentially suggestive of foraging (see Fig. 3). b Mean dive backscattering (dB) plotted relative to maximum dive depth (m) and c relative to longitude
