Think of your picture as a picture of climate....very average, never right in detail for any specific place or time.Yes, yes, I am confident that more knowledgeable members like yourself and the SAR have better understandings of the currents than I. Your post #176 is impressive, but beyond my comprehension, so I offered the simplistic view - knowing from experience that some don't even know about the north Atlantic gyre.
And after Cameron is found, rescued, treated for the effects of floating so long, and gets back online here - we are going to discuss PLBs & dive canisters. He posted about maybe getting one a few years back. I just packed mine up this morning to send off for it's 5½ year battery service. I'd be embarrassed to ever have to use my ACR 2881, but confident that the company will replace it for free if I ever need to.
Think of mine as today's weather map....as accurate as the data and models can make it. The BIG difference is the Loop Current, which is the dominating current in the region right now.....and it is heading north....not northwest or east or northeast.
