This technology allowed scientists to determine the manner in which the sea lions died, because traumatic deaths and non-traumatic deaths left different "signatures" on the recorders. The pups had tags implanted in their abdomens to record body temperature, surrounding light levels and other conditions during the sea lions' lives.Īfter each sea lion's death, the tag data was transmitted to satellites and then analyzed by the researchers. They monitored 36 juveniles in the Kenai Fjords and Prince William Sound region of the Gulf of Alaska from 2005 to 2011. The population has declined by 80 percent from its peak about four decades ago. The researchers focused on the endangered western population of the Steller sea lions (Eumetopias jubatus), which is the largest member of the eared seals family.
