KUALA LUMPUR, March 28:

The team involved in one of the most challenging hunts for the black box of the missing Malaysia Airlines (MAS) flight MH370 will face yet another obstacle. This time from whales.

Australian news agency news.com.au quoted a marine expert from Curtin University’s Centre for Marine Science and Technology as revealing this challenge.

Dr Alec Duncan told the news agency that oceans were “extremely noisy” places, with noises emitted by marine mammals among the many background sounds posing difficulties to the search mission.

“They wouldn’t confuse the signal, but it may make it harder to detect based on the background noise from whales and other sources,” he was quoted as saying.

The news agency reported that the underwater locator beacon attached to a aircraft cockpit voice recorder and flight data recorder, emitted a distinctive ping sound at a frequency of 37.5 kHz once per second while marine mammals made sounds on different frequencies.

Duncan said the search team would need to get as close as possible to the beacon to limit sound absorption within the water and interference.

“The Southern Ocean is a hell of a noisy place because of the weather,” news.com.au quoted Duncan.

“It’s not a calm part of the world and that will limit the detection range.

“There’s quite a lot of things going on.”

The search area for MH370 has been updated today following a new credible lead, according to the Australian Maritime Safety Authority (Amsa).

Based on information given by the international investigation team in Malaysia, Amsa, in its statement, said the search would now “shift to an area 1,100km to the northeast”.

The decision to shift  followed advice from the Australian Transport Safety Bureau (ATSB), saying it was the most credible lead to where the debris might be located.

Australia is currently taking the lead in the search and rescue operation for the missing MH370 in the southern Indian Ocean.

It was earlier reported that satellite data from China as well as Australia, and later France, indicated possible debris sighting 2,500km south west of Perth.

The search and rescue operation faced deteriorating weather conditions yesterday and had to  call off operations just before noon.

It resumed this morning as weather conditions had reportedly improved. A Chinese Ilyushin IL-76 aircraft took off from Pearce Base in Perth and headed towards the search area.

Another 9 aircraft have also been tasked to participate in today’s search.

According to Amsa, the new search area is roughly 319,000 square kilometres and estimated to be 1,850km west of Perth.

“The new information is based on continuing analysis of radar data between the South China Sea and the Straits of Malacca before radar contact was lost,” the statement said, adding that analysis indicated the plane was travelling faster than previously estimated.

  • QUOTE OF THE DAY

“A review found that some of the opinions were baseless or off target…This is the challenge in the new environment, especially the media practitioners, because they are chasing news. They want to be the first in the news because (some) want to form perceptions, not to ensure accuracy of the news. It (accuracy) is as if it is secondary. When a perception is formed, it is very hard to scrape it off.”

Prime Minister Datuk Seri Najib Razak stressing that differing opinions are not a problem as long as they are based on facts and are constructive in nature. He noted that many believed the false report that 40,000 Bangladeshi voters were waiting to vote for Barisan Nasional (BN) in the last general election.
