Australian Vessel Picks Up Ping in Indian Ocean, Moves to Investigate - Malaysian Officials Promise ‘Same Level of Vigour and Intensity’ Going Forward
As the first month of the search for the missing Malaysia Airlines jetliner draws to a close, Australian officials said they had detected pulse signals in the southern Indian Ocean, one day following a similar report by Chinese authorities. An Royal Australian Navy vessel, the Ocean Shield, picked up a separate pulse signal Sunday approximately 300 nautical miles (555 kilometers) from its location, Air Chief Marshal Angus Houston, the chief coordinator of Australia’s Joint Agency Coordination… (www.frequentbusinesstraveler.com) Plus d'info...
Different media are aptly covering the news from many angles and in many ways .
" MH370 investigators work to confirm signals heard by Australian, Chinese vessels "

" Oz: New pings sound like MH370 black box signals "

They all express some common concerns.
Whether the Chinese ships picked up the 'right' pings which were reportedly very weak ?
And, to confirm the source of the 'pings' before the batteries of the BBs die down !
IMHO, there is absolutely no need to dwell on these two.
Why ?
Any engineer or even physicist with indulgence in Sound having a vee bit of common sense knows and will recall that sound travel in waves in a medium . The signal strength(quality) though reduces over square of distance, but it depends heavily on the quality of medium also. Like in case of light ! If the medium is clean(!) the the signal will be 'clean' and so on. Therefore attaching too much qualitative concerns to 'pings' received by Chinese vessel will be irrelevant.
Now, coming to batteries weakening out or burning out, there is no need to panic.
As on date, we boast a lot about our competence in the word " Nano Technology". And today may be as good a day as any to test it ! Be it to pick up 'new but weak' signals AND/OR to 'enlarge' and analyse the signals received .
Battery strength being zero, notwithstanding !
Good luck to engineer-scientists involved .

Friends, allow me to augment/supplement my fore going comment by the following

Explaining about the effect of medium(water) on waves(electromagnetic)
Pleasant hunting with knowledge.

I have no idea of the sea depths involved !
Can some one enlighten ?
Can some one enlighten ?
Another article @ frequent business traveler states the water depth is 15,000 feet in the area where the purported pings were detected. Unless the military is involved, the CVR and FDR may never be recovered at that depth.
Principle of Synergy.
This one such situation for the first.
