Despite cost projections that the search will cost $60 million, Abbott said it would be expanded to cover more of the ocean floor. An Orion 3C plane will still be on standby in case wreckage is seen, he said.
The search for missing Malaysia Airlines Prada Wallet Outlet Flight 370 is shifting entirely to the Indian Ocean floor and away from possible surface debris, Australian officials announced Monday.
Monday, nine planes and 12 ships were searching, according to the Joint Agency Coordination Center. Abbott said the search would shift underwater after contracts are awarded during the next several weeks for sonar equipment that can be towed behind ships to join the Bluefin 21 submarine already in use.
Ten civil aircraft and 19 military planes have flown during a total 41 days out of 52 since the plane went missing, Abbott said. The planes covered more than 1.7 million miles during 334 flights.
Searching the ocean surface presented challenges from the start because planes were operating at the limits of how far and how long they could fly to scan an area more than 1,000 miles from Australia.
3 miles deep in this area, and the line running from the ship is much longer. Dave Gallo, the project leader at Woods Hole Oceanographic Institution that found Air France Flight 447 at the bottom of the Atlantic, said ships have trouble turning quickly or tightly while dragging such a long cord is a search pattern similar to mowing a lawn.
"If everything goes perfectly, I would say we'll be doing well if we do it in eight months," said Angus Houston, a retired air chief marshal who is leading the search for Australia. He warned that weather and equipment failures could slow things down.
"Enormous efforts will continue to be made," Abbott said.
"Imagine trying to mow the lawn by towing a lawn mower behind a helicopter," Gallo said. "It's not the best way to do things."
and the USA, according to the crash report.
The surface search is being curtailed because debris from the Boeing 777 200ER that disappeared March 8 with 239 people aboard should have become waterlogged and sunk by now, according to Australian Prime Minister Tony Abbott.
data recorders, until April 8. The underwater search wasn't able to find the recorders based on those signals, which Abbott called baffling and disturbing. Navy, is in its 16th day of searching the ocean floor with sonar. Technicians program the sub, then retrieve it to download data and look for echoes from man made objects rather than rocks on the ocean floor.
Malaysia search shifts from surface to ocean floor
"This is probably the most difficult search in human history," Abbott said. He said the search "is entering a new phase."

One difficulty of towing sonar devices behind a ship is that the ocean is nearly Prada New Bag
"We will be seeking some appropriate contribution from other nations involved, but we will ensure that this search goes ahead," Abbott said.
The $60 million cost estimate would make the search one of the costliest in history. Search and rescue operations for Air France Flight 447, which took nearly two years after the crash in 2009, cost a total of 80 million euros from France, Brazil Cheap Prada Bags
The Bluefin 21 moves at about walking speed. It has searched 155 square miles, and Abbott said the primary underwater search zone is 21,622 square miles, which is likely to take months longer even with additional search equipment.
No debris from Flight 370 has been confirmed nearly two months after it disappeared on its way from Kuala Lumpur to Beijing. Ships were unable to confirm initial satellite photographs and plane sightings of possible wreckage from the flight.
