At least 30 bodies of AirAsia Flight 8501 victims have been recovered, authorities said, as ships with sensitive equipment searched for the plane's fuselage, ABC News reported.
Five of the victims were found still strapped in their seats, Indonesian navy official Col. Yayan Sofiyan said.
Bambang Soelistyo, head of Indonesia's National Search and Rescue Agency, said the search would be stepped up as long as the weather allowed.
"We will focus on underwater detection," said Soelistyo, adding ships from Indonesia,Malaysia, Singapore and the United States had been on the scene from before dawn today to try to pinpoint the wreckage and the all-important black boxes, or the flight data and cockpit voice recorders.
The Airbus A320 crashed into the Java Sea Sunday with 162 people on board. A number of the bodies were found by a US Navy ship, said Suryadi B. Supriyadi, operation coordinator for the National Search and Rescue Agency.
