Question: In the ocean, isnt T/dt really one parameter, not two independent ones?

In the slide, dt is the amount of "simulated" time between two time physics time steps. T is meant to be the total duration of the physics simulation (careful: it's the simulated time, not the wall-clock time to actually run the simulation on a machine), so the total number of time steps is T/dT. An alternative, but equally expressive two-parameter set up would be dt and num_timesteps.
You need two parameters because num_timesteps time steps each of length dt is a different simulation than the same number of time steps, but with double the time (increased dT) per time step.
