sea surface temperature chart

Hi everyone, I am in the process of purchasing a 32 foot Albemarle Express
sport fishing boat. I am looking for a web site that shows sea surface
temperatures. I'm interested in fishing the gulfstream off of the Carolina
coast.

Does anyone regularly use these and if so can you recommend a site? I'm
looking for one that I can also obtain lat / long info from so that I could
actually locate the eddies and fingers on the edges of the gulfstream.

A free site would be great, since I'm pretty broke right now after buying
this boat, and I need lots of new gear as well, but I'd entertain a
reasonably inexpensive site as well.

Thanks!

Gary
