Unusual water temp rise in Caribbean

[HeeBGBz]

I posted this in the Weather group but I'll ask it here too.

Water temps in the NW Caribbean rose 4.5 degrees in a four hour timeframe. What could cause this?

1. geothermal vent?

2. Underwater alien spaceship?

3. Shit, isn't this the big pre-disaster moment in . . .

The Day After Tomorrow?

4. Hope not n/t

6. Imagine what I'm thinking

here in the Northern Caribbean. Damn this is cause for concern.

5. Is it freezing in New York yet?

8. Holy shit, you're right-

That movie scared the hell out of me.
I wish someone who knows about these things
would post to this thread.
Yikes, it sounds really bad, but we
can all hope it's not, eh?
Wishful thinking out loud,

7. Geothermal heat source or possibly man-made using thermal nuclear

...devices. Why? Weather control maybe, manufacturing hurricanes...I would not put it past the Bush Administration to pull a stunt like that given all of the secrecy during the last 5 1/2 years.

9. An Eddy Off The Stream Will Do It Every Time

I watch sea surface temperatures all the time, its something advid off-shore fishermen do. Its not all that uncommon to see big jumps when a small eddy spins off the Gulf Stream, or the Florida Stream as the case may be.

Anyway it happens all the time, if you can catch one just right it can be great for the fishing right on the edge.

PS: When you are right on top of the change in a boat you wouldn't believe how much different it is on one side to the other. Sometimes in the space of 5 or 10 feet the temperature will jump 10 degrees, the water color will change, and fish pile up on the boundry. Happy time!

10. Thanks for telling us-

I'm glad to hear it is nothing unusual!
Every day I wake up wondering what fresh hell
we will learn of next...

11. Interesting

It was being discussed on a weather forum I visit and they seemed to think it was rather unusual.

Thanks for the input. I'm still gonna keep an eye on that area for anything strange.

12. Might Be In That Area

You see them all the time off the East Coast, and I know they sometimes swing toward the inside of the stream as well. If you go to Rutgers web site they may still show sea surface temperatures for the entire Atlantic, you can watch the eddys spin off. I used to time fishing trips by watching them, and I have a friend down in Virginia who watches every day as well. If we'd see an eddy spin off the stream we'd try to figure when it would get within reach of some place like Hatteras and then go try to find it.

When you get on one you'll usually catch fish. Small bait fish are generally unable to withstand fast temperature changes so as a school moves along when they hit one of the boundaries they just stack up. That concentration caused by the temperature change allows large predators to feed with a minimum of energy expenditure. So when you find the temperature break you find fish. There is also often a salinity difference at the same time. It can really be a quite spectacular sight. It is the only thing I regret about aging; the thought that I won't be able to get out them for very much longer. It is beauty beyond explanation.

13. Thanks for the tip about the fish. Getting my gear ready tonight. n/t

15. Sounds great

I would love to spend time out on the water. Wish I had a boat.

14. We often see that kind of phenomenon in "our" lake

it's fresh water of course but the baitfish ("shad" around here) congregate right at the boundaries
and the 'eating' fish chase them. (We can usually see the shad jumping as they try to escape the
predators) :D
It's a good spot to catch white bass which are yum.

16. Ooh, I love white bass

Tasty!

17. probobly just a minor geothermal nuclear device

nothing to lose any sleep over.....................

18. I could explain it to you, but let's say my oath I took as a sub service

sailor prevents it...
:silly:

It is called a "thermal layer," and subs really do use it to help remain undetected.
