The last communications between the South Korean ferry that sank on Wednesday and traffic services reveal panic and indecision by the crew.
In the newly released transcript, a crew member repeatedly asks if there were vessels on hand to rescue passengers if evacuation was ordered.
The captain has said he delayed the move for fear people would drift away.
After three days, divers have now entered the ferry and retrieved 32 bodies, bringing the death toll to 64.
However, another 238 people are still missing. Some 174 passengers were rescued.
