The search area is approximately 77,580 square kilometers, and good weather is expected throughout the day.

According to the JACC, the underwater search continues with Australia's vessel Ocean Shield at the northern end of the defined search area, and Chinese ship Haixun 01 and British HMS Echo at the southern end.

The pulse signals consistent with those from aircraft black box were detected by Ocean Shield and Haixun 01 over the weekend in separate locations at a depth of 4,500 meters undersea. But further confirmation is needed as to whether these detections are related to MH370.

The Malaysian jetliner is believed to have crashed in the southern Indian Ocean although no confirmed debris has been found since it went missing on March 8 on its way from Kuala Lumpur to Beijing with 239 people on board.
