Toward regional characterizations of the oceanic internal wavefield

KL Polzin, YV Lvov - Reviews of geophysics, 2011 - Wiley Online Library
Many major oceanographic internal wave observational programs of the last 4 decades are
reanalyzed in order to characterize variability of the deep ocean internal wavefield. The …

Internal wave turbulence in a stratified fluid with and without eigenmodes of the experimental domain

N Lanchon, DO Mora, E Monsalve, PP Cortet - Physical Review Fluids, 2023 - APS
We present laboratory experiments on turbulence in a linearly stratified fluid driven by an
ensemble of internal gravity waves which approaches statistical homogeneity and …

Interacting internal waves explain global patterns of interior ocean mixing

G Dematteis, A Le Boyer, F Pollmann, KL Polzin… - Nature …, 2024 - nature.com
Across the stable density stratification of the abyssal ocean, deep dense water is slowly
propelled upward by sustained, though irregular, turbulent mixing. The resulting mean …
