On the spatial statistics of free-surface turbulence and the complementarity of 'dimples' and 'scars'
Daniel R. Kjellevold, Jørgen R. Aarnes, Omer M. Babiker +2
The air--water interface governs the exchange of heat and gas between natural water bodies and their surrounding environment. Turbulence beneath the free surface imprints character…

Experimental investigation relating free-surface features to sub-surface turbulence
Omer M. Babiker, Jørgen R. Aarnes, Ali Semati +4
Turbulent flows beneath a free surface play a central role in the Earth system, yet their coupling to observable surface features remains incompletely understood. Recent studies us…

Mapping surface height dynamics to subsurface flow physics in free-surface turbulent flow using a shallow recurrent decoder
Kristoffer S. Moen, Jørgen R. Aarnes, Jørgen R. Aarnes +3
Near-surface turbulent flows beneath a free surface are reconstructed from sparse measurements of the surface height variation, by a neural network algorithm known as the SHallow R…
