E. A World-Renowned Marine Mammal Research Center

Narrator: This is Science Today. The University of California , Santa Cruz is
home to one of the top centers for marine mammal research in the world. At the Long Marine Laboratory, researchers have developed specially designed tanks and equipment for studying marine mammal diving physiology, bioacoustics, and cognition. Biologist Terrie Williams, who has been studying marine mammals such as dolphins, says their research program tries to accomplish two different things.

Williams: We've got the up-close physiology, biology of these animals that we do in a controlled setting like this. And then we want to know how does that really work out in the wild? What does a wild dolphin need in order to make it?

Narrator: Williams says they've been looking in particular at whether temperature is a big factor in these animals' lives.

Williams: How much do they need to eat during different seasons and then how much of a metabolism change can we expect because of the idea of global climate change and water temperature changes that we're certainly seeing off our coast?
