September 11 - First Ocean Current Charts Created (1785)
Today in 1785
the first Gulf Stream
charts were created.
At sea off Massachusetts, oceanography sleuth Benjamin Franklin, nearly 80 years old, during his last voyage from Europe to the United States, conducts temperature and vegetation studies on the Gulf Stream.
Beginning when Benjamin Franklin was the colonial Deputy Postmaster, he tried to explain why mail was slower when coming from Europe than going the other way. Franklin's study produced a wealth of information on the physical and biological properties of the Gulf Stream, including its first charting, which was one of the first charts of any of the world's ocean currents.
