Current shear and turbulence during a near-inertial wave
Röhrs, Johannes; Halsne, Trygve; Sutherland, Graig; Dagestad, Knut-Frode; Hole, Lars Robert; Brostrøm, Gøran; Christensen, Kai Håkon (Journal article; Peer reviewed, 2023-04-11)Surface currents and turbulent mixing were observed during a near-inertial wave (NIW) using an accousting doppler current profiler (ADCP) and satellite-tracked drifters. Drifter trajectories sampled at three depth levels ... -
Ocean wave tracing v.1: a numerical solver of the wave ray equations for ocean waves on variable currents at arbitrary depths
Halsne, Trygve; Christensen, Kai Håkon; Hope, Gaute; Breivik, Øyvind (Journal article; Peer reviewed, 2023)Lateral changes in the group velocity of waves propagating in oceanic or coastal waters cause a deflection in their propagation path. Such refractive effects can be computed given knowledge of the ambient current field ... -
On the short-term response of entrained air bubbles in the upper ocean: a case study in the north Adriatic Sea
Benetazzo, Alvise; Halsne, Trygve; Breivik, Øyvind; Strand, Kjersti Opstad; Callaghan, Adrian H.; Barbariol, Francesco; Davison, Silvio; Bergamasco, Filippo; Molina, Cristobal; Bastianini, Mauro (Journal article; Peer reviewed, 2024)Air bubbles in the upper ocean are generated mainly by waves breaking at the air–sea interface. As such, after the waves break, entrained air bubbles evolve in the form of plumes in the turbulent flow, exchange gas with ... -
Resolving regions known for intense wave–current interaction using spectral wave models: A case study in the energetic flow fields of Northern Norway
Halsne, Trygve; Bohlinger, Patrik; Christensen, Kai Håkon; Carrasco, Ana; Breivik, Øyvind (Journal article; Peer reviewed, 2022)Oceanic current forcing in spectral wave models have recently been demonstrated to have a large impact on wave heights at scales between one and up to several hundred kilometers. Here we investigate the impact of such ... -
Wave modulation by strong currents: A study in the Lofoten Maelstrom and surrounding areas
Halsne, Trygve (Doctoral thesis, 2024-06-07)Bølger og strøm – allestedsnærværende trekk ved havet – er i en konstant tilstand av gjensidig vekselvirkning. Disse prosessene forårsaker sterkt inhomogene sjøtilstander. Samspillet dem imellom regulerer utvekslingsprosesser ... -
Wave Modulation in a Strong Tidal Current and Its Impact on Extreme Waves
Halsne, Trygve; Benetazzo, Alvise; Barbariol, Francesco; Christensen, Kai Håkon; Carrasco, Ana; Breivik, Øyvind (Journal article; Peer reviewed, 2024)Accurate estimates of extreme waves are central for maritime activities, and stochastic wave models are the best option available for practical applications. However, the way currents influence the statistics of space–time ...
