"NOAA To Investigate Dolphin Deaths During Navy Sonar Exercise"

"Federal authorities said on Thursday they were investigating the deaths of two California common bottlenose dolphins that stranded and died on beaches just a few miles apart in San Diego a day after the U.S. Navy conducted a brief exercise with sonar.

Jim Milbury, the West Coast spokesman for the National Oceanographic and Atmospheric Administration (NOAA), said that necropsies were being performed and that an investigation was underway.

The dolphins, apparently part of a population of 323 remaining California common bottle nose dolphins, were found on Oct. 21 at Imperial Beach and the Silver Strand, less than 10 miles apart."
