Diapycnal Mixing and Along Isopycnal Spreading at the Southern Rim of the Guinea Upwelling Region: A Tracer Release Experiment


The objective of A3 was to estimate integral horizontal spreading and vertical mixing rates by conducting a deliberate trace release experiment in the Guinea Dome open ocean upwelling regime (GUTRE). The observed mixing and spreading was used to benchmark SFB 754 models (A1, A2 and B1) and allowed for estimation of the exchange of oxygen between the ambient water and the Eastern Tropical North Atlantic oxygen minimum.
