Teams searching for the missing Malaysia Airlines plane have reacquired signals that could be consistent with "black box" flight recorders.
Australian vessel Ocean Shield heard the signals again on Tuesday afternoon and evening, the Australian official leading the search said.
Work was continuing to refine the search area before a submersible could be sent down.
