>>> FINALLY TONIGHT HERE, THE AMERICAN SCIENTISTS AND THEIR SOLUTION TO SAVE A DOLPHIN. AMERICA STRONG. TONIGHT, IN CLEARWATER, FLORIDA, JUST OUTSIDE TAMPA, THE AMAZING RESCUE. THE TEAM AT CLEARWATER MARINE AQUARIUM LEARNING A YOUNG DOLPHIN HAD SOMEHOW LOST ITS WAY FROM THE OCEAN AND WAS STUCK IN A SMALL CREEK FOR THREE WEEKS. THE SCIENTISTS FIRST MONITORING THE DOLPHIN, THEN COMING UP WITH A REMARKABLE PLAN. A TEAM OF 28 BIOLOGISTS FORMING A HUMAN CHAIN, CREATING A VISUAL AND SOUND BARRIER, COAXING THE DOLPHIN OUT. BRITTANY BALDRIA IS THE SENIOR RESCUE BIOLOGIST. >> OUR MAIN GOAL WAS JUST TO CREATE A STRAIGHT LINE ACROSS FROM US. SO, WE WERE SHOULDER TO SHOULDER, NO GAPS. >> THE ONLY WAY OUT -- A SMALL OPENING UNDER A BRIDGE. ANDY GARRETT WITH FISH AND WILDLIFE ON THE BOAT RIGHT BEHIND THAT HUMAN CHAIN. >> JUST KIND OF ENCOURAGING IT THAT, YOU KNOW, THIS IS NOT WHERE YOU WANT TO BE. THE NOISE FROM TRUCKS AND CARS GOING OVER THE BRIDGE IS A SOUND BARRIER FOR THE DOLPHIN, IT DOESN'T WANT TO LEAVE THE AREA. >> THE TEAM SLOWLY, CAREFULLY MOVING IN, SPLASHING THE WATER CLOSER AND CLOSER TO THE OPENING. AND FINALLY -- >> DID HE GO? >> HE WENT! YEAH! >> HE WENT THROUGH! >> IT WORKED. AND RIGHT HERE TONIGHT -- >> HELLO, DAVID. >> THAT SENIOR RESCUE BIOLOGIST ON THE MOMENT. >> IT WAS VERY EXCITING. ONCE WE GOT TO THE END, IT FINALLY MADE THE DECISION TO SWIM UNDERNEATH THE BRIDGE AND WAS THROUGH ONTO THE OTHER SIDE. >> SHE TELLS US THE DOLPHIN IS NOW SAFELY BACK OUT TO SEA AFTER THE SCIENTISTS AND THAT HUMAN CHAIN COMING TO THE RESCUE. BACK OUT TO SEA. NO SMALL VICTORY.
