This isn't entirely on ocean currents, but related. The site I originally set up, the Stevens Ocean Observatory, shows tidal waters off New York City. It plays currents as a movie of 48 frames interactively, and you can see the salinity and temperature changes at the mouth of the river. You can see Coriolis as the plume curves to the right, and that Coriolis even makes the New York side of the ...

The book was awe inspiring, and sad as you see what has been culturally lost.
