    • Estimating waves via measured ship responses 

      Nielsen, Ulrik Dam; Bingham, Harry B.; Brodtkorb, Astrid H.; Iseki, Toshio; Jensen, Jørgen Juncher; Mittendorf, Malte; Mounet, Raphaël Emile Gilbert; Shao, Yanlin; Storhaug, Gaute; Sørensen, Asgeir Johan; Takami, Tomoki (Peer reviewed; Journal article, 2023)
      Optimisation of energy efficiency and operational performance as well as assessment of safety levels and emissions of marine operations require detailed information about the acting wave system. It is possible—with an ...

    • Extra Strain Rates in an unsteady spilling breaking wave 

      Lucarelli, Alessia; Lugni, Claudio; Falchi, Massimo; Felli, Mario; Brocchini, Maurizio (Journal article; Peer reviewed, 2018)
      We analyze the extra strain rates that characterize a curved, thin mixing layer induced at an unsteady spilling breaker. We focus on the flow curvature, which induces some extra rates of strain that should be accounted for ...

    • The fish ability to accelerate and suddenly turn in fast maneuvers 

      Paniccia, Damiano; Graziani, Giorgio; Lugni, Claudio; Piva, Renzo (Peer reviewed; Journal article, 2022)
      Velocity burst and quick turning are performed by fish during fast maneuvers which might be essential to their survival along pray–predator encounters. The parameters to evaluate these truly unsteady motions are totally ...

    • The sinking of the El Faro: predicting real world rogue waves during Hurricane Joaquin 

      Fedele, Francesco; Lugni, Claudio; Chawla, Arun (Journal article; Peer reviewed, 2017)
      We present a study on the prediction of rogue waves during the 1-hour sea state of Hurricane Joaquin when the Merchant Vessel El Faro sank east of the Bahamas on October 1, 2015. High-resolution hindcast of hurricane-generated ...

    • Underwater hyperspectral imaging as an in situ taxonomic tool for deep-sea megafauna 

      Dumke, Ines; Purser, Autun; Marcon, Yann; Nornes, Stein Melvær; Johnsen, Geir; Ludvigsen, Martin; Søreide, Fredrik (Journal article; Peer reviewed, 2018)
      Identification of benthic megafauna is commonly based on analysis of physical samples or imagery acquired by cameras mounted on underwater platforms. Physical collection of samples is difficult, particularly from the deep ...

    • Wave dispersion in moderate channel turbulence 

      Pilloton, Chiara; Lugni, Claudio; Graziani, Giorgio; Fedele, Francesco (Peer reviewed; Journal article, 2023)
      We study channel turbulence by interpreting its vorticity as a random sea of ocean wave packet analogues. In particular, we investigate the ocean-like properties of vortical packets applying stochastic methods developed ...
