New research reveals that ocean mixing off the Amazon coast peaks not only near wave origins but also 230 km offshore, where different wave paths may intersect. This overlap likely forms strong solitary waves that intensify turbulence. Based on the AMAZOMIX-2021 cruise, which collected direct turbulence measurements alongside hydrographic data, the study quantifies dissipation and the relative contributions of tidal shear and large-scale shear. This mixing helps redistribute heat and nutrients, playing a key role in climate regulation and marine ecosystems.
