Yeah, but the surface circulation on the Atlantic coast is southerly; it turns northerly (the Gulf Stream) farther out on the shelf. In the heat of the summer you want to go to Atlantic beaches in a westerly breeze, causes upwelling and makes the water cooler. In the Pacific there is near-constant upwelling controlled by the current regime, disrupted only by El NoNo. Got very little shelf in the Pacific, especially in northern CA.

I really love oceanographic stuff.

Yah. That's one of the drivers. Combine that with cooling of water made saline in the tropics, then transported to subpolar regions - and you get this huge slow oceanic conveyor belt of water, draped around our rock like seams on a softball.

They think that if this conveyor snags or shifts, we get sudden and violent climatic change. One of the Global Warming questions is how much "tension" is on the conveyor, and how much can it take. Biiig questions.
