" Cortez was perhaps the first to send large numbers of ships from Mexico northward through the Florida Straits, then eastward following the clockwise motion of the Gulf Strea…m to return to Spain. A visit with any of the shipwreck museums will reveal the results of the unsuccessful voyages. A notation in the Herrera's summary of the log of Ponce de Leon's voyage log, on April 22, 1513, noted, "A current such that, although they had great wind, they could not proceed forward, but backward and it seems that they were proceeding well; at the end it was known that the current was more powerful than the wind." This is probably the first written evidence of the Gulf Stream and Ponce de Leon is considered its discoverer. It was not until six years later that one Anton de Alaminos set sail for Spain from Vera Cruz, Mexico following the Florida coastline northward before turning eastward to Europe. This same Anton de Alaminos was the chief pilot aboard Ponce de Leon's ship on his earlier trip and had also sailed with Columbus on his last voyage. Some historians credit Alaminos with the discovery of the Gulf Stream, since he was the first to take advantage of it."
