WebIsopycnal mixing is when surface waters moving into the interior of the ocean typically run horizontally, along the isopycnal layers, settling into their correct density-dependent layer (Talley, 67). This process is important for ventilating the ocean with oxygen. Diapycnal mixing is the movement of water by either upwelling or downwelling. WebUpwelling and downwelling describe mass movements of the ocean, which affect both surface and deep currents. These movements are essential in stirring the ocean, delivering oxygen to depth, distributing heat, and …
