The Australian Maritime Safety Authority said Friday's search concluded "without any sightings."
"The Australian Defense Force, the U.S. Navy, a commercial jet and merchant ships supported today’s search effort in a 23,000-square-kilometer [14,291-square-mile] search in the Australian search and rescue region," a release from AMSA said on its website.
"The Royal Australian Navy’s HMAS Success is en route to the search area," the release said. "Two merchant ships are now in the search area."
Inclement weather Thursday hampered efforts to spot the debris, the largest piece of which would be about the size of shipping container. The weather and visibility was better Friday.
The debris was spotted on satellite images some 1,400 miles from the west coast of Australia in the Indian Ocean.
Australian Prime Minister Tony Abbott on Friday defended the government's decision to announce the find.
He said Australia owes it them them "to give them information as soon as it's to hand, and I think I was doing that yesterday in the Parliament."
The Boeing 777-200 disappeared March 8 on a flight from Kuala Lumpur, the capital of Malaysia, to Beijing, China, with 239 people on aboard.
"It could just be a container that has fallen off a ship," he said of the debris. "We just don't know."
