The underwater drone scanning the ocean for Malaysia Airlines Flight 370 began its ninth mission Monday with "no contacts of interest" in its last eight, the Australia's Joint Agency Coordination Centre said.
The Bluefin-21 has scanned about two-thirds of the intended territory without finding any sign of the missing plane.
These efforts may be a main focus of the search, but they aren't the only part.
Australia's Joint Agency Coordination Centre announced Monday morning that up to 10 military aircraft and 11 ships would participate in the day's search for the Boeing 777 and the 239 passengers and crew on board.
The weather isn't making the task easier.
Tropical Cyclone Jack is circulating northwest of the search area. And while it won't hit directly, this system should increase winds and rains.

A high-altitude avalanche Friday killed 12 Sherpa guides and seriously wounded three in the single deadliest accident on Mount Everest, officials said.
Four others are missing, said Madhu Sudan Burlakoti of Nepal's Tourism Ministry, adding that six people were injured in total.
A group of about 50 people, mostly Nepali Sherpas, were hit by the avalanche at more than 20,000 feet, said Tilak Ram Pandey of the ministry's mountaineering department.
The avalanche took place just above base camp in the Khumbu Ice Fall.
The climbers were accounted for, Pandey said. "Rescue teams have gone ... to look for the missing."
Before Friday, the deadliest single-day toll was from an accident in May 1996, when eight climbers disappeared when a huge storm hit. Their tragic story was chronicled in Jon Krakauer's bestselling book "Into Thin Air."

In a sea of uncertainty, two bits of good news emerged Wednesday.
Searchers picked up fresh signals that officials hope are locator beacons from the data recorders of the missing Malaysia Airlines Flight 370.
The Australian ship Ocean Shield had first picked up the underwater pulses Saturday. But then, for the next three days, nothing.
On Tuesday, the ship once again reacquired the signals. That's four signals in the same broad area: two on Saturday; two on Tuesday. All of the signals are within 17 miles of one another.
Actor Mickey Rooney, one of Hollywood's brightest stars in the 1930s and 1940s, died Sunday in California, the Los Angeles County Coroner's office said. He was 93.
The diminutive 5-foot, 2-inch Rooney began his acting career shortly after his first birthday, appearing on vaudeville stages with his parents. He was born Joseph Yule, Jr. on Sept. 23, 1920 in Brooklyn, New York.
He became a star in the 1920s when he began appearing in dozens of shorts based on the popular "Mickey McGuire" comic strip, but he shot into Hollywood's stratosphere in his next film series, starting in more than a dozen "Andy Hardy" films between 1937 and 1946.
Rooney also starred as half of one of the most famous screen partnerships in film history, teaming with actress Judy Garland in a number of the "Andy Hardy" films. He also starred with her in several Busby Berkeley musicals, including 1940's "Strike up the Band" and "Babes on Broadway" a year later.
From 1939 through 1941, Rooney was the No. 1 box office draw in the United States.
He earned an Oscar nomination for his role in the World War II film "The Bold and the Brave" in 1956.
Rooney's personal life generated almost as much talk as his film career. He walked down the aisle eight times. His first wife was starlet Ava Gardner.
