Question 3 transcript:
"There are many angles to that; one of the earlier ones that was particularly exciting was the discovery of the 'Meddy' or Mediterranean Eddy. These are circular discs of water that spin around in the horizontal. They tend to be quite thin, not much more than a sheet of paper, that is, if they're one kilometer this way (vertical) and more than a hundred kilometers in diameter. These lens are very long lived and the one that we first found, the original discovery was the one off the Bahamas in 1976, and that was so warm and salty, that 'Meddy', that we were convinced it came from the Mediterranean outflow. And indeed, when people started looking in the East Atlantic they found these things, so that seemed like a wonderful confirmation. Twenty years later we are convinced that that was not actually from the Mediterranean but came from much farther North in the North Atlantic by a different pathway, but much more rapidly. And it is one of the stronger tales that we have, how you can be quite convinced of a certain answer to begin with and than many years later, or later on, discover that what you were so convinced of, we (now) think turns out to be wrong. So, science is very much an evolving process."
