Diving with Alaska’s Steller Sea Lions

For Immediate Release
Feb. 17, 2005

Despite their bulk, Steller sea lions dive with grace and agility. They can
stay submerged for up to eight minutes and dive to depths of 3,000 feet to
maintain their diverse diet.

Jennifer Burns, assistant professor of biology at the University of Alaska
Anchorage, will discuss how diving and foraging behavior changes over the
lifespan of the marine mammals in her lecture, “Diving With Alaska’s Steller
Sea Lions.” The presentation will be held on Monday, February 21, at the
Wendy Williamson Auditorium, UAA.

In addition to explaining the sea lions’ diving capabilities, Burns will
offer insight on why the Steller sea lion population has dropped throughout
the world. Since 1970, the number of Steller sea lions has decreased from
280,000 to below 100,000 worldwide. A quarter of the current Steller sea
lion population resides in Alaska, predominantly along the Aleutian Islands.

The hour-long lecture is free and will begin at 7:15 p.m. at the Wendy
Williamson Auditorium. All ages are welcome!
