The Parking Lot Effect on Palm Island Seabed

So here I am yesterday on my small yacht with some friends trying to escape the heat of Dubai so we stopped between the Royal Mirage hotel beach and the Palm island. As soon as the yacht stopped I jumped in to cool off, only to feel even hotter in the water!!

How can that be? Water is supposed to cool you off not feel like a Jacuzzi, but hey it could be something with water being trapped between the beach and the Palm Island. So we decided to move on and pulled the anchor of boat only to find it’s full of cement on it, not sand!!!

That when a friend said “this is the parking lot effect, the asphalt on the seabed produces heat instead of the sand absorbing the heat.”

You have a boat?
O_O

Guess I'll just crawl back in to my mirdiff hole

Somebody got an F in physics, I see.

ColOman said...

why you saying that Skeptic

Skeptic Al said...

Coloman, the poster claims that the new seabottom produces heat.

I'd like to know by which chemical or physical mechanism this heat is produced.

Skeptic, the concept of heat gain and loss is relative, I think what the poster meant is that when the heat conveyed by the sun rays don't get absorbed through the sand at the sea bottom, it ends up reflected to the water. That means you have a heat gain (i.e. heat produced)...

The cement must be laid by the experts (after careful study) to protect the coral etc.!
After all we have to care for the environment.

Without getting into the specifics of this case, it is possible for human construction to change the temperature locally, creating an "urbanheat island". Something like that might be what Col Oman's friend was talking about.

Hallo Coloman, sense of heat on your skin is quiet subjective. And you have to accept, that the region of Persian Gulf is one of the hottest worldwide. But I suggest, examine the issue first with a thermometer, comparing temperature of this region concreted over and a region still left in natural state. And when you find out something suspicious, you become activist at Greenpeace. PS. I wish to have warmer a bit water here in Europe.

Ok, I should have added this to matters into prospective, when we went out in the open water, right after that the water was a lot cooler, and I was not the only who felt it.

Interesting.

ColOman said...

so there you go Skeptic.

Skeptic Al said...

Where do I go, Coloman?

If you said that the water felt warmer because of a hard, shallow bottom and lack of circulation, I would have no complaint.

The claim that the new sea bottom produces heat was, is, and shall forever be false, unless there is very shallow geothermal activity below the surface.

skeptic al,
coloman is possibly referring to the heat of hydration.If there was asphalt or more specifically concrete on the bed, it is possible that the area would be warmer because of the heat released by concrete as it hardens.

my heart bleeds for you and your small yacht.. :)

wondering if it is heat that can be harnassed for energy generation purposes..

jomster.... Well said. That's what I was referring to.

I haven't swum in summer for the past couple of years, but the water really is bath hot, isn't it? Now if that could be combined with cool summer breezes (rather than hot humid ones) this really would be an earthly paradise ;)
