"Most of the pilot whales that were stranded in the Florida Everglades swam into deeper water on Thursday while rescuers tried to chase the rest out to sea by banging on pipes and revving their boat engines."
"Wildlife workers had hoped the cacophony would encourage the whales to leave the shallow water where dozens of short-finned pilot whales were first sighted on Tuesday afternoon in a remote part of the Everglades National Park.
The National Oceanic and Atmospheric Administration, or NOAA, said via Twitter that of the 51 whales originally stranded, 11 had died and five went missing overnight Wednesday.
NOAA said the 35 swimming away were about 9 miles from shore, in about 18 feet of water, with about 10 or 15 miles to go before they reach deeper waters."
