Yes, still hopeful
I would like to see the other 2 ships carrying/towing a beacon locator search that same site and report it's findings

Two ships -- the Australian navy's Ocean Shield and the British HMS Echo are carrying sophisticated equipment that can hear the recorders' pings, one ship has the US Navy's towed pinger locator that can detect a ping in 20,000 ocean depth but it still needs to be within a certain range (1-2 mile i think) to be able to pick up that signal..

I thought the Chinese had a towed pinger locator but I was mistaken, what the Chinese have is a detector that was placed in the ocean just below the water surface.
I am not sure at what depth this tool can pick up the locator beacon signal but I am hopeful

That is where my initial confusion arose from, knowing there were two ships out there (Ocean Shield and HMS Echo) that were equipped to hear the pings, and why they didn't record anything. Knowing now they weren't in the same location as the Chinese explains much. Therefore, yes, it would be interesting if those two ships moved to the same area and picked up the signal. Apparently the signal is intermittent, however, and seems it may be the FDR with the battery being very weak.

MOO

Ah, I was wondering what everyone was talking about regarding the time as I thought there would be a time difference but I just saw Perth time and Kuala Lumpur time is the same.

The sun rose at 6:08am that day for info.

But depending how far west of Australia the flight was, it might have still been dark at 8am Perth time. The search area is a couple of hours behind Perth time, iirc.

So...do we know if the main search IS being moved today or not? I read ^^^^^ that they are thinking about it?

I can't imagine at least part of the search would not be moved.

By the position of the shadow, the sun would be close-ish to being overhead. And the sun would be directly behind the plane - so the plane was either travelling west before noon, or east not too long after noon.

imo

Moon shadow?

Not all satellites need the sun to relay an image back to earth. The satellite/s that took that pic may need the sun but not all.

It would certainly make sense that there would be satellite imagery capability at night! Certainly not that it is necessarily available for the general public. We can probably all agree that nightime is actually when we see the most planes in the sky. You can't miss their bright lights.

I believe I located the equipment the Chinese are using and this Benthos locator can detect pings in 600ft of depth as opposed to the US Navy's towed pinger locator, iirc, that the Ocean Shield is towing which can detect a ping in 20,000ft ocean depth.

I heard on CNN, an engineer from Dukane Seacom, that ocean temp (cold), or marine vegetation, the topography of the ocean floor (trenches, basins, shelves etc...) can have an effect on the hearing of the signal

Ah, of course - I'm a bit foggy today

It sounds as though Angus Houston isn't ready to tell us that yet. :sigh:

The RCC in Australia has spoken to the RCC in China and asked for any further information that may be relevant.

The deployment of RAAF assets to the area where the Chinese ship detected the sounds is being considered.

I will provide further updates if, and when, more information becomes available.

She said the signal, detected at 4.30pm local time, lasted for one-and-a-half minutes, and while consistent with the frequency standard Boeing jet black boxes would use, that it was "not exclusive" and there was possibility that the signal could be from "other equipment".

Very discouraging. You are correct (600ft). What are the chances of a rogue SAR team picking a spot, for reasons only they know, where no one else is looking, plunking in a detector with a 600ft range and picking up a signal?

It's a really easy mistake to make though. But lots of people overseas don't realise just how far away from Perth the search area is. I think the first search area was about the same as the distance between New York and Houston or from London to Moscow.

It was likely around dawn when the plane crashed, depending on its position.

JerseyGirl · Apr 5, 2014

Anish Patel, president of US black box beacon manufacturer Dukane Seacom, said he was "highly sceptical" about the report.

"Let's get some additional assets in the water so we can corroborate, before we get everyone's hopes up," he told CNN.

Kiwi :blowkiss:

but yeah I should definitely know these things

Malaysia's defense minister and acting transport minister, Hishammuddin Hussein, was hopeful.

"Another night of hope - praying hard," he tweeted in response to the latest discoveries.

This pic shows the location of the possible black box signal (red dot) in relation to the search zones.
The photo is attributed to GISTDA, Australian Govt, US NTSB, Malaysian Govt.
Hope it is okay to post.

Wow. It seems to be smack in the middle of the existing search area.

JerseyGirl · Apr 5, 2014

Australian planes may be sent to the southern Indian Ocean search area where a Chinese ship looking for flight MH370 detected a 'pulse signal' at a frequency used by aircraft black boxes.

JerseyGirl · Apr 5, 2014

He's back!! Mitchell sighting on CNN now! :loveyou:

____

Anish Patel, president of pinger manufacturer Dukane Seacom, said that was the standard beacon frequency for both black boxes: the cockpit voice recorder and the flight data recorder.

‘‘They’re identical,’’ he said.

ElleElle · Apr 5, 2014

Are there new estimates of fuel, flight etc, since this new "breaking news"?

The map shows MH370 going South, yet the "pulse" is looking more East?

The capability of the locator the Chinese were using is what gives me pause. One would think the FDR is in water much deeper than 600 ft. If the US Navy's pinger locator had picked up a signal, I would be much more confident it actually is the FDR.
