Fig. 6From: Development of an animal-borne “sonar tag” for quantifying prey availability: test deployments on northern elephant sealsSonar tag acoustic data suggestive of prey pursuit. a One hour subset of acoustic data associated with translocated seal #4 showing strong targets and high scattering observed during foraging-type dives in off-shelf waters south of Monterey Bay (region 2 in Fig. 2). b Zoom-in shows targets observed getting closer and closer to the seal on successive pings as the animal increased and then decreased in depth, possibly indicative of prey pursuitBack to article page
