Title: Unrelated, but possibly useful ROV footage
Post by: Chris Owens on February 02, 2012, 04:03:48 PM
This video on Youtube contains some ROV footage of a freighter, the Port Nicholson,  sunk during WWII off Massachusetts by a Nazi U-Boat.  Although the conditions are entirely different (cold oxygen and nutrient-rich north Atlantic rather than warm tropical Pacific), this still might be useful as an example of what known man-made objects look like after 75 years at 600 meters depth, when viewed from an ROV.  It may or may not help people to calibrate their eyes.

That's a great find Chris, very informative indeed. One thing that I don't think has been mentioned or, it may have been overlooked is that the wreckage we are looking at in the TIGHAR ROV footage hasn't always been at 300 metres. It began life at 1 metre? on the reef and, as it was pulverised into little bits over the years  and swept gradually down into the depths over a period of 75 years? So at any given time during those 75 years? bits of wreckage accumulated differing levels of coral growth depending on how long they spent at any given depth. There's a good section on coral growth on the TIGHAR site, I will post the link later. All the above is IMHO and, is open to correction.

Good find, Chris - thanks for sharing this.

Anyone who is seriously interested in what's going on in the ROV thread ought to watch this - very educational about what it's like to sort these wrecks out.

I think some people are gifted at spotting these things and sorting them out - and the rest of us struggle, but it's not hard to be a fan of discovery, that's for sure.

This is a fascinating video. Not only because of the wereck, and the ROV, but what man can do if he comes up with the resources. Raising the cargo from 600 feet is amazing. Like rasing parts of the Electra from 800 feet.
Truly fascinating.
