"A team of civilian researchers led by entrepreneur and philanthropist Paul G. Allen has announced they have found the wreck of the World War II cruiser USS Indianapolis (CA 35), which was lost July 30, 1945."

 

18000 ft deep.

 

 

That's deep!

Paul Allen's group has  now found the USS Ward off the Philippines which fired the first shots of World War 2 in the Pacific Theater for the US during the Attack on Pearl Harbor.

That oil tanker has sunk

Burning oil tanker sinks off China after one week

An oil tanker burning in the East China Sea for more than a week has finally sunk, Chinese media say.

The Sanchi and a cargo ship collided 260km (160 miles) off Shanghai on 6 January, with the tanker then drifting south-east towards Japan.

Iranian officials now say all 32 crew members - 30 Iranians and two Bangladeshis - on the tanker are dead.

The tanker was carrying 136,000 tonnes of ultra-light crude but Chinese officials say there is no major slick.

China Central Television said that the Sanchi had gone down after "suddenly igniting" around noon (04:00 GMT).

https://arstechnica.com/science/2019/01/oxford-scientists-successfully-recreated-a-famous-rogue-wave-in-the-lab/

 

In this latest experiment, the Oxford scientists generated two sets of waves in a circular water tank at the University of Edinburgh and made sure they crossed each other at various angles, the better to recreate the conditions under which the Draupner wave had formed. In these conditions, the wave doesn't break like you'd normally expect. Wave breaking usually serves to limit a wave's maximum height, but that limiting factor doesn't occur when waves cross each other at large angles.

The sweet spot turned out to be an angle of 120 degrees: when the groups of waves crossed at that angle, they formed a wave that scaled neatly with the height and length of the Draupner wave (albeit at 1/35th the size of the original).

 

...

 

Despite numerous anecdotal eyewitness accounts about rogue waves, there wasn't any hard scientific evidence for them, so such claims were dismissed as myths or legends. In fact, a French naval officer in 1826, Jules Dumont d'Urville, reported seeing a 108-foot-high wave in the Indian Ocean and was roundly ridiculed by physicist François Arago for his trouble. At the time, scientists didn't think waves could be higher than 30 feet.

 

...

 

In 1995, a powerful rogue wave slammed into an offshore gas pipeline platform operated by Statoil in the southern tip of Norway. Dubbed the "Draupner wave," it generated intense interest among scientists, since the platform's various sensors and instruments provided precise details about the wave's dynamics. Rogue waves had long been considered a myth, so those readings—combined with damage to the platform consistent with a wave some 84 feet high—provided crucial evidence for the phenomenon

That's interesting. I've seen some work on freak waves previously (as in ~15 years ago), but that was looking at 2d waves where one wave would suck energy out of the waves either side of it - building on the work in a 3d pool is neat

Oh wow.  This is a fucking cool shot from above the wreck of the Hornet. Note how intact the wreck is, with the island largely intact.  Some of the stern is missing, or crumpled in the sonar shadow.  But man, for a ship that took such a beating she looks largely intact.  @Collimatrix, @A. T. Mahan,

That's pretty cool. Some of the other pics shows very little decay to a lot of the ship!

A photo of the wreck (the only one I managed to find so far, they haven't all been released yet):

What's interesting is that the photo contradict the two existing hypothesis: either a snorkel leak, or a diving bar issue.

Both would have caused a significant tilt of the sub, but it was found flat on the bottom and without any damage to the bulb or it's rear extremity.

But an internal explosion may have occurred in the central part of the ship (may be the batteries).

Wouldn't a snorkel leak flood the centre compartment, bringing the sub down evenly?

 

I guess it depends on where the flood start.

The leak could have come from the exhaust which is connected to the engines at the rear.

If the flood happened here I guess the sub would have tilted backward.
