Here are some photos in no particular order of sunken objects located by side scanner sonar (those towed buoys you see in those oceanographer documentaries). I only post them to show what the technology is capable of, as well as show how spooky it can be- imagine you're looking at miles and miles of nothing on the screen, and then suddenly you see a wrecked ship nobody has seen for a hundred years. I will leave it to others to identify the subject matter...
Enjoy!

I didn't realize how detailed it could be. The last one looks like a body. I would guess a human body wouldn't last long down there

Down and side imaging technology is awesome. It has really advanced in the past 10 years. Some of the new fishing graphs can produce amazing images, when properly set up. Most can be had for around 1k.

Quote HistoryQuoted:
Why/how does it show shadows? The technology works by taking a photograph via sound waves. The shadows are actually areas where the sound waves are being blocked by the wreckage. That said, the shadows are every bit as valuable as the image of the wreckage. This one clearly shows the silhouette of the wreck and identifies what it is...the actual wreck is the horizontal shape beneath the shadow...

Great find OP!
I spent a year on a Navy Oceanographic Unit mapping parts of the Pacific and IO. Our granularity to "see" stuff was measured in fathoms, and we were scooting along at 20 knots. We found all kinds of mountains, etc. I always thought it would have been awesome to see stuff at this detail. |

In 1845 an expedition led by Sir John Franklin left England in two ships to explore the Arctic. The ships was subsequently trapped in ice and the crew had to abandon them. The entire crew wound up dying and some of the graves discovered later on were determined to have been cannibalized.
The reason why I mention this? They found the wreck of the HMS Erebus, one of the Franklin expedition ships.

Think of the sounds waves as a laser, it will bounce off the object back towards the transmitter. The sound will never reach where the "shadow" is so it registers as no response or "nothing there". |
