The Bluefin-21 was deployed again on Tuesday night from the Australian Naval ship Ocean Shield. The first mission on Monday evening was aborted early, after the sub's emergency warning mechanism automatically brought it back to the surface, after it descended beyond its 4 and a half kilometer limit. Data from the mission was downloaded and analyzed but it's shown no indication of the missing plane, with the data only showing a rocky seabed.

Meanwhile, the surface search is continuing. Up to 14 aircraft and 11 ships have been deployed in Wednesday's search effort. They'll search an area of some 55,000 square kilometers, some 2,000 kilometers northwest of Perth. The surface search operation is being hampered by South easterly winds with isolated rain showers. There are also sea swells of up to 2 meters and limited visibility of around 5 kilometers. So far, the search for debris on the ocean surface has only recovered floating junk and other objects unrelated to the missing plane.
