NOAA Fisheries Service Working with Volunteers to Rescue Stranded Dolphins in the Florida Keys NOAA Fisheries Service scientists and volunteers are continuing their efforts to save dozens of dolphins stranded in the Florida Keys. More than 60 rough-tooth dolphins were found on flats and sandbars and in a nearby canal Wednesday about a quarter mile off Marathon. So far, six dolphins have died and about 35 others are being treated for dehydration as NOAA biologists try to determine why they came to shore. Blair Mase, a scientist with NOAA Fisheries Service, said today that 20 of the deep-water dolphins have been returned to the ocean. “This is the fourth mass stranding of rough-tooth dolphins and we’re trying to find out why,” she told the CBS “Early Show” today. Later today, teams will begin moving some of the sick dolphins to care facilities along the Keys or on the mainland.
