    • Acoustic Propagation Underneath the Arctic Sea-ice 

      Hope, Gaute (Doctoral thesis, 2018-10-04)
      The main objective of this project is to study the effect of sea-ice on underwater acoustic wave propagation. Three main parameters define how acoustic waves react to the presence of seaice: (i) the roughness of the underside ...

    • A dataset of direct observations of sea ice drift and waves in ice 

      Rabault, Jean; Müller, Malte; Voermans, Joey; Brazhnikov, Dmitry; Turnbull, Ian; Marchenko, Aleksey; Biuw, Martin; Nose, Takehiko; Waseda, Takuji; Johansson, Malin; Breivik, Øyvind; Sutherland, Graig; Hole, Lars Robert; Johnson, Mark; Jensen, Atle; Gundersen, Olav; Kristoffersen, Yngve; Babanin, Alexander; Tedesco, Paulina Souza; Christensen, Kai Håkon; Kristiansen, Martin; Hope, Gaute; Kodaira, Tsubasa; Martins de Aguiar, Victor Cesar; Taelman, Catherine Cecilia A; Quigley, Cornelius Patrick; Filchuk, Kirill; Mahoney, Andrew R. (Journal article; Peer reviewed, 2023)
      Variability in sea ice conditions, combined with strong couplings to the atmosphere and the ocean, lead to a broad range of complex sea ice dynamics. More in-situ measurements are needed to better identify the phenomena ...

    • Exploring the Microseismicity of the Gakkel Ridge from Arctic Sea Ice 

      Hope, Gaute (Master thesis, 2013-06-03)
      Monitoring of microseismicity is an important tool to understand the magmatism, tectonics and hydrothermal circulation of a mid-oceanic ridge. In the presence of sea ice, use of ocean bottom seismometers is not practical, ...

    • Identification and quantification of soundscape components in the Marginal Ice Zone 

      Geyer, Florian; Sagen, Hanne; Hope, Gaute; Babiker, Mohamed; Worcester, Peter F. (Peer reviewed; Journal article, 2016)
      Acoustic experiments using an integrated ice station were carried out during August 2012 and September 2013 in the Marginal Ice Zone (MIZ) of Fram Strait. The two experiments lasted four days each and collected under-ice ...

    • Measured and modeled acoustic propagation underneath the rough Arctic sea-ice 

      Hope, Gaute; Sagen, Hanne; Storheim, Espen; Hobæk, Halvor; Freitag, Lee (Peer reviewed; Journal article, 2017-09)
      A characteristic surface duct beneath the sea-ice in the Marginal Ice Zone causes acoustic waves to be trapped and continuously interact with the sea-ice. The reflectivity of the sea-ice depends on the thickness, the elastic ...
