Wreck of Australian Warship HMAS Sydney Found?
Mendy writes "Tim Ankers, a British archaeologist, claims to have found the wreck of the HMAS Sydney, lost with all hands in the Indian Ocean during World War II. He says that he's done this from the comfort of his home using software he wrote called Merlindown, which can analyze satellite photographs at different wavelengths to 'peer 75 meters into the earth and 16,000 meters beneath the seas.'"

Big deal - a ship is rather large. Can you find my keys?
.. paranoid crackpot leftover from the days of Amiga.
You're not alone. Apparently this story came out last week and Akers' claims already rejected by those searching for the ship.

But Ted Graham, the chairman of the Perth-based volunteer company HMAS Sydney Search (HMA3S), says finding the shipwreck using the methods Mr Akers said he employed was impossible.
"All the advice we're getting is saying Tim's claims are technically not possible," Mr Graham told AAP.
"We've spoken to a whole lot of people and got advice from various people including technical people in government departments and they have all stated that what Tim's claiming is complete rubbish.
"I think it's just complete nonsense."
My brother in law was an archeologist who utilized ground based sonar devices to look for Native American ruins. The resolution on the unit he was using was something like 10 meters below the ground, and required a very slow transit time and a good deal of energy.
Yes, tech progresses, but 75 m from outer space using only UV, Xray, and Infra photography? I am very skeptical.
On another note... if this new process is true then construction will have to pretty much halt in many areas of Southern California. There are stringent rules in place governing building on areas that contain either significant fossil remains or any sort of Native American relics. Several hundred million USD per year is spent on archeological surveys to determine what may be beneath a construction site. Various companies have reputations for finding little if anything, and so environmental groups sometimes employ other companies that usually find a good deal of things that will prevent construction.
Decently resolved pictures up to 75 m below the surface will prove what some archeos in the field already believe to be true... under current laws it should be almost impossible to build anywhere in the greater L.A. area because of the shear volume of fossil record.
They pulled two gigantic whales out of a toll road excavation in the middle of the desert... etc.

Nobody ever considers this end of things.

Uh, if this is true then it is a big dea. A very big deal.

Do you have any idea of how valuable salvage rights of all the sunken wrecks that this tool could potentially uncover would be? No? Well, here's a clue:

That's one wreck. Worth half a billion dollars. Makes you think, doesn't it?

Mariana trench is only about 10900 meters. Whats he imaging at 16000? Sounds a bit crusty to me.

His claims of course are WAY suspect - light of whatever wavelength needs to get to the target, then reflect BACK to the sensor, and well, the reason water is blue is that it's pretty much impervious to most wavelengths, and as far as IR, that wreck that deep would probably have cooled down really well by now to the ambient water temperature. I have seen sunken wrecks from satellite images though ... Scapa Flow has quite a few scuttled wrecks from WW II.

But americans tend not to be aware of it, because a certain egomanicial general by the name of McArthur had this nasty tendency to ignore allies and claim that everything was done by the Americans.
Australia had, and still has, excellent soldiers. Mac Arthur was an egomaniac and no one other than Mac Arthur got credit for anything, regardless of whether they were American or Australian. However things are not as simple as you suggest. Australia had many of its forces in Europe trying to save England. Recall that the war had started in Europe years earlier than in the Pacific and England was just barely hanging on and absolutely needed Canadian, Australian, South African, etc forces. When Mac Arthur was ordered/tricked to leave the Philippines he was expecting to mount a counterattack to rescue the American forces left behind. When he arrived in Australia he found no counterattack/rescue force, not even enough of a force to defend Australia should Japan attempt a major invasion. The Australian generals were planning to trade most of the country for time and only defend the south eastern (?) quarter, to be fair that was where most of the population and development was located.
Having Scuba Dived regular on 100-150 ft deep wrecks, I too find this a little hard to believe. Even at that depth the amount of light getting through, the colour of the "wreck" and so on, would suggest that this is unlikely, even more so at greater depths. And that was in the pristine waters of PNG.
We found that the best mechanisms for finding as yet unfound wrecks were plain old research. We requested and got a copy of the microfilms of the WW2 records for the area from the US Archives. Slowly and meticulously (reading Microfilm projected onto the fridge door), following each report, we ultimately ended up finding around half a dozen new wrecks. The report of a Corsair that clipped a tree, while trying to line up for the airstrip, and spun into the bay, prompted a search for a tree stump, and and following a logical path to the airstrip, a probably location - sure enough a deep dive (180 ft - lots of decompression) found it. Biggest coup was the talk of an abandoned airstrip on a remote island in the Solomon Islands. Sure enough, worked out roughly where, found a single like reference to the "local name" for it, and sure enough, found three WWII fighters still sitting at the end of a punched metal runway, as if waiting for orders...
As someone said, an archaeologist developing software that the spooks, and/or mining types haven't been able to. That's a bit far fetched.
I would suggest "text scans" of historical documents may be more useful.

This is nonsense: I work in the earth observation satellite industry and there are no ultraviolet or x-ray sensors on earth observation satellites (for obvious reasons - the earth does not emit x-rays, and UV is absorbed by the atmosphere.)
Optical sensors can see at most a few metres into clear water. At infrared wavelengths water is black and opaque. "Light passes through matter"? No, it doesn't. Didn't The Times use to have a science correspondent?
