November 4, 2015 — HONOLULU (AP) ” The National Marine Fisheries Service on Wednesday said it was investigating the death of two dolphins found washed ashore in California shortly after Navy ships were using sonar in nearby waters.
The animals are being analyzed to try to determine what caused them to get stranded, agency spokesman Jim Milbury said.
The dolphins were common bottlenose dolphins, Navy spokeswoman Lt. Julie Holland said. They were found Oct. 21 at Imperial Beach and at Silver Strand beach in San Diego.
