Fluid dynamics is always quite interesting...

I’ve experienced the “superheated water” effect in a microwave oven, where water is heated well beyond the boiling point, but it doesn’t form any bubbles, and appears to not be boiling. Break the surface tension and WHOOSH! It flashes to steam and boils violently in an instant!

I can’t see this affecting drownings unless it affects buoyancy somehow.

As ships sail over a layer of warm water sitting over saltier, or colder, layers, waves form in the boundary between the two layers. As these waves grow, they form a gulf beneath the ship, sucking away its speed.

No. No. No. That is just Rove's weather machine warming up for the 2009 hurricane season.

Evil water....

I surfed a lot in the Dominican Republic in the 80s. There were a few locals but nobody else was surfing there in those days. Very lonesome but very cool.

One day I was in the water at Rio San Juan with a friend who had married a Dominican girl and knew the breaks. It was a good day, overhead but not intimidating, just the two of us in the water and nobody on the beach. There was some sun but mostly it was overcast.

We were paddling out after a set, the reef was about 75 yards out. Very suddenly the water seemed to turn black and slick. we kept paddling but we weren't getting anywhere. There was something very scary going on, it felt as though a malevolent energy was passing just under the surface.

I looked over at Charlie, the look on his face told me that he was as scared as I was. Without a word we turned around and beat it into the beach. We sat there watching and trying to figure out what the hell was out there.

I never figured out what it was but I undertand now how our ancestors believed in spirits and monsters in the ocean.

Bell curves and such - maybe there’s a condition of “more” power. And could it be harnessed?

[Smokin' Joe]

It sounds like a standing wave on the interface. In effect, running into a strong current that ordinarily would not be felt, but the distortion of the boundary brings close enough to the surface to be a problem.

Any 'silent service' folks out there run into this?

water directly linked to drownings, huh.

Where is the graphic of Captain Obvious?
