Ocean energetics relates to the flow of energy between different scales of motion down to the scale of turbulent dissipation and mixing. The ocean is a vast thermodynamic machine, powered by the sun, the winds, and the tides. There is no concept more fundamental to the ocean than energy; it characterizes the flow of waters and the transfer of heat between warm and cold regions. The flow of energy in the ocean system, together with the flow of energy in the atmosphere, controls the climate state of the Earth.
My studies focus on the transfer of energy from large- and mesoscale oceanic flows to smaller dissipative scales. Internal waves are central to this process, as they are perhaps the only mechanism that acts in the range of scales between the mesoscale (eddies) and the turbulent processes that lead mixing and diffusion.
