Research biologist Don Calkins and one of his subjects, a 5-year-old steller's sea lion named Woody, check each other out at the Alaska SeaLife Center in Seward on Tuesday. Calkins, who has studied sea lions for 25 years, is continuing his research at the $56 million wildlife hospital and research center with the help of a congressional grant. The 7-acre center, built with restitution money from the Exxon Valdez oil spill, private donations and revenue bonds, will open to the public today.
