	SSC San Diego TD 627 Revision D - Chapter 1
		This paper discusses analysis of data to determine the extent of impact on loud impulse sounds during fish predation by odontocetes.
		Acoustic examination of the targets failed to reveal consistent and obvious echo cues for the discrimination of shape, but replicated measurements of target strength for each target revealed differences in standard deviations that paralleled the performance of the animal.
		To test the effect of depth on the hearing of an odontocete cetacean, two white whales were trained to dive and station on a platform at 5, 100, 200, or 300 m in the Pacific Ocean and whistle when they heard a 500 ms tone from a hydrophone.

	Ecosystem Change of Steller Sea Lions - Marine Mammal Research Consortium
		Trophic levels were estimated for each species of marine mammals and compared with published estimates derived using stable isotope ratios.
		Trophic levels ranged from 3.2–3.4 in baleen whales and sea otters, to 3.8–4.4 in most pinnipeds and odontocete whales, to 4.5–4.6 in killer whales.
