    • 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 ...
