To me personally, the field is fun because it gives me a perspective on all the processes which drives the weather and climate. I like watching the skies and the seas.

Scientifically the most exciting areas right would be:

• mixing efficiency: The ocean has a layered structure and it takes 1000s of years for the deep ocean to rise up. Many are trying to understand at what limits the turbulence in ocean currents drives the cold saline deep ocean to starts mixing with warmer fresher waters on the top more effectively. An important question in our changing climate.
• convection: a classic problem where the heated walls drive convective motion. People are still trying to understand different parameters and how it affects the kind of convection we get. Convection is everywhere: ocean currents transporting heat between the latitudes and, atmosphere which determine where the deserts and rainforests are etc.
