Question 2 transcript:
"The focus of my research is very much the Gulf Stream and surrounging waters, no question about that. I have worked with other systems like the Agulhas current, which is a Gulf Stream-like system around South Africa, and so forth; but the Gulf Stream as it flows from the U.S. East coast all the way up to the Nordic Seas is what we have focused on mostly over the years. Why we have focused on that is, well, it's interesting. The technologies that we have developed to study ocean currents using drifters seem quite apropos, in other words, a good technique to apply to the Gulf Stream. We have indeed; we've learned an awful lot using the float technology in the Gulf Stream. We have learned how in shallow depths, for example, the Gulf Stream can act as a barrier between waters around it, so waters will go along the Gulf Stream. Where as in depth, the Gulf Stream, thanks to it's meandering, will actually act to stir up the waters on each side. And these are things that might have been rather difficult to understand with other techniques. But with the floats streaming through the Gulf Stream on different density surfaces or depths we can see the Gulf Stream is, I shouldn't use the word river, but acting like a river at shallow depths, separating the two sides, and as a mixer or blender at depth. There are many more aspects to that but maybe in a nutshell."
